SYSTEM AND METHOD FOR POLICY DRIVEN PROTECTION OF REMOTE COMPUTING ENVIRONMENTS
A system that incorporates teachings of the subject disclosure may include, for example, determining examination results based on sensory information obtained from sensors operating in a deployed environment, wherein the sensory information includes a combination of more than one of temperature, position, motion, and mission status. Software agents conduct reviews of examination results based on sensory ranges. Encryption key fragments are generated in response to the reviews of the examination results. The encryption key fragments are combined, to obtain a cryptographic session key. A clear-text version of encrypted sensitive information is obtained via the cryptographic session key responsive to the examination results falling within the sensory ranges. Decryption of the encrypted sensitive information is prevented responsive at least one of the examination results falling outside the sensory ranges. Other embodiments are disclosed.

FIELD OF THE DISCLOSUREThe subject disclosure relates to a system and method for policy driven protection of remote computing environments.
BACKGROUNDRemote installation of software is common in the context of commercial computing. For example, it is a routine matter for software and system vendors, such as Microsoft®, Adobe® and Apple® to remotely install updates, sometimes referred to as “patches” for their products running on consumer platforms, such as personal computers, workstations, tablet computers and smart phones. Some devices, such as smart phones routinely recharge their batteries when placed in a cradle, allowing software vendors to install software upgrades while the smart phone is resting in the cradle, even when the device is not in use.
In some instances, such software upgrades can occur automatically, e.g., without user interaction or approval. For example, a user may pre-authorize software updates from one or more authorized software vendors for certain applications, e.g., operating systems or security software. In other instances, the availability of such updates can be determined and presented to a user without updating the software automatically. Rather, installation of any of the available software upgrades can be accomplished in response to user authorization, which can be provided, e.g., on a case-by-case basis.
Anyone with a smart phone or personal computer running any of the popular operating systems or security software is accustomed to the frequent occurrence of such software updates. It would not be unusual to expect several software updates per week, e.g., for a smartphone hosting a modest number of applications. In order to make such software updates minimally invasive or otherwise unnoticeable to a user, a user's data files are typically not removed or otherwise modified. For example, a user configuration file, data files, and the like, will remain substantially unchanged on the device being updated. Such frequent software upgrades are less common in sensitive applications, such as in a military applications due to security concerns. Namely, each modification to software and/or data on a sensitive platform poses an opportunity for the introduction of malware, spyware, and the like.
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The subject disclosure describes, among other things, illustrative embodiments of policy driven protection of remotely operated computing environments. Other embodiments are included in the subject disclosure.
One embodiment of the subject disclosure includes a process that includes receiving, by a system including a processor, multiple software agents, and configuring, by the system, a network of the multiple software agents according to a predetermined policy. The process further includes facilitating, by the system, secure communications among software agents of the network of the multiple software agents according to the predetermined policy, and determining, by the system, a state of one of the system, a system environment within which the system operates, or a combination thereof, based on the secure communications among the software agents of the network of the multiple software agents. A computing environment is facilitated by the system to support a mission application. The facilitating of the computing environment is conditional on the state of the one of the system, the system environment, or the combination thereof, according to the predetermined policy.
Another embodiment of the subject disclosure includes a system, including a memory to store instructions and a processor in communication with the memory. The processor, responsive to executing the instructions, performs operations including receiving multiple software agents and configuring a network of the multiple software agents according to a predetermined policy. The processor further performs operations including facilitating secure communications among software agents of the network of the multiple software agents, and determining a state of one of the system, a system environment within which the system operates, or a combination thereof, based on the secure communications among the software agents of the network of the multiple software agents according to the predetermined policy. A computing environment is facilitated to support a mission application. The facilitating of the computing environment is conditional on the state of the one of the system, the system environment, or the combination thereof, according to the predetermined policy.
Yet another embodiment of the subject disclosure includes a process, including implementing a predetermined policy and sending, by a system including a processor, multiple software agents to a first device. The multiple software agents, when installed upon the first device according to the predetermined policy, cause the first device to perform operations. The operations performed by the first device include configuring a network of the multiple software agents according to the predetermined policy, and facilitating secure communications among software agents of the network of the multiple software agents according to the predetermined policy. The operations performed by the first device further include determining a state of one of the first device, an environment within which the first device operates, or a combination thereof, based on the secure communications among the software agents of the plurality of software agents and facilitating a computing environment to support a mission application. The facilitating of the computing environment is conditional on the state of one of the first device, the respective environment, or a combination thereof, according to the predetermined policy.
The techniques disclosed herein relate generally to the protection of computing environments and more particularly to the protection of remote computing environments that include a controllable platform and a controller to remotely control the controllable platform. One or more of the controllable platform, the controller or a combined control system of the controlled platform and the controller, include one or more applications, sometimes referred to herein as mission applications. The applications can include communication between one or more elements or components, such as circuit boards, modules, processes or combinations thereof of the controllable platform, the controller or the combined control system that communicate with the control module. By way of non-limiting example, such control systems can include industrial processes, e.g., in association with manufacturing and/or supply chain applications, e-commerce applications, and control systems in which the controllable platform is a mobile platform. Some examples of mobile platforms include robots, automobiles, which can be controlled remotely, piloted aircraft which communicate with remote controllers, and unpiloted aircraft (drones), both military and civilian, which communicate with remote controllers. More generally, the techniques disclosed herein apply to securable remote computing environments in which elements communicate with one another over one or more communication channels, e.g., in which network connections of such communication channels can be predefined.
In operation, the system configuration server 102 obtains policy information from the policy definition file 104 and configuration information from the configuration file 106. Policy information can also be included in one or more files of functions, which are run on the system 100 by installed software agents. The policy information causes the installed software agents to examine the system and in at least some instances, to provide cryptographic material based the results of their examinations. The system configuration server 102 sends information to the first device 110a to cause generation of a network of software agents, at least some of which can reside on the first device 110a. In the illustrative example, the configuration server 102 sends information causing the generation of a first networked group of software agents 124a, including a first software agent 126a and a second software agent 126b. The first networked group of software agents 124a is configured to support secure communications between the first and second software agents 126a, 126b. The first networked group of software agents 124a can be configured to perform one or more tasks, such as determining an encryption key, e.g., for decrypting sensitive information. The sensitive information can represent one or more of the operating system 118, the application programs 120 or the data structures 122. The sensitive information can originally reside in the memory 116 prior to generation of the first networked group of software agents 124a, or be provided from another source, such as the configuration server 102 before, after, or at the time of generation of the first networked group of software agents 124.
The software agents are computer programs configured to achieve one or more objectives. The software agents that can include one or more attributes of artificial intelligence, e.g., exhibiting some aspects of learning and/or reasoning. Alternatively or in addition, the software agents are computer programs that can include one or more attributes of autonomy, e.g., capable of modifying a manner in which they achieve their objectives. The software agents can be distributed, e.g., being executed on one or more of the same processor, different processors of the same computer, and/or physically distinct computers or processors. In at least some of the embodiments disclosed herein the software agents are configured in multi-agent systems, including distributed agents that do not necessarily have capabilities to achieve an objective alone. Such distributed agents can be arranged into the networks of software agents disclosed herein to facilitate communication among two or more software agents of the networks of software agents.
In at least some embodiment, one or more of the software agents 126a, 126b receives sensor information from one or more of the sensors 114a, 114b. The sensor information can provide information obtained from or otherwise indicative of the first device 110a. Alternatively or in addition, the sensor information can provide information obtained from or otherwise indicative of an environment within which the first device 110a is operating. According to one or more of the policy definition file 104 and the configuration file 106, one or more of the software agents 126a, 126b implements a respective function 105 based upon at least a portion of the sensor information. By way of illustration, a system designer can determine an authorized environment within which the first device 110a is authorized to operate. The authorized environment can have one or more aspects that are detectable by way of sensory information obtained by one or more of the sensors 114a, 114b. The system designer determines which sensor information from one or more of the sensors 114a, 114b is suitable for arriving at a determination that the first device 110a is operating in an authorized environment and what values or range of values represent positive results indicative of the authorized environment. The one or more functions 105 implemented by the software agents 126a, 126b can provide a result indicative of an authorized environment in response to sensor data indicative of the authorized environment. Such a successful determination can be used to allow one or more of the software agents 126a, 126b to perform one or more other functions.
In an illustrative example, the software agents 126a, 126b include functionality to produce a decryption key to allow for decryption of encrypted sensitive information. Alternatively or in addition, the software agents 126a, 126b install one or more of the operating system 118, the application programs 120 and the data structures 122. By way of illustrative example, the software agents 126a, 126b allow for an installation process, e.g., an application program 120 running on the first device 110a, and/or a similar process running on the configuration server 102. The installation process can re-image the 1st device, e.g., by re-imaging at least a first operating system 118. The operating system 118 can include operating system function(s) and supporting file structure sufficient to proceed with normal operations, or a simplified version, e.g., a kernel, requiring further enhancements before normal operations are possible.
According to the policy information file 104 and configuration information from the configuration file 106 and various functions 105, the system configuration server 102 sends further information to the first device 110a to cause generation of a second network of software agents 124b, including a first software agent 128a and a second software agent 128b. The second networked group of software agents 124b can also be configured to support secure communications between the first and second software agents 128a, 128b. The second networked group of software agents 124b can be configured to perform one or more of determining another encryption key, e.g., for decrypting further sensitive information. The further sensitive information can represent one or more of enhancements to the operating system 118 installed or otherwise configured by way of the first group of software agents 124a, the application programs 120 and/or the data structures 122. Alternatively or in addition, the further sensitive information can represent one or more of application programs 120. In at least some embodiments, the process can be repeated again, e.g., producing a third networked group of software agents 124c, including a first software agent 130a and a second software agent 130b. In some embodiments the first networked group of software agents 124a can be removed or otherwise rendered inoperable before installing the second networked group of software agents 124b, and the second networked group of software agents 124b can be removed or otherwise rendered inoperable before installing the third networked group of software agents 124c. Thus, only one of the networked groups of software agents is operable at any given time. Alternatively, the first networked group of software agents 124a is not removed of otherwise rendered inoperable before installing the second and/or third networked groups of software agents 124b, 124c, such that more than one of the networked group of software agents 124a, 124b, 124c can be operable at the same time.
In at least some of the embodiments, one or more of the first, second and third networked groups of software agents 124a, 124b, 124c can be configured, e.g., according to the policy, to periodically monitor the sensor data. The expected sensor data, as identified in one or more of the policy file 104 or the configuration file 106 can include expected environmental conditions that vary, e.g., according to a particular mission. Thus, it is conceivable that appropriate environmental conditions may vary over the course of a particular mission. The groups of software agents 124a, 124b, 124c can be configured to periodically monitor sensors and take action conditionally in response to the updated sensor data.
A characteristic configuration of the networked software agents 124a, 124b, 124c is that the first device 110a, e.g., a controllable platform or process, such as a vehicle, has an embedded operating system 118 that receives input from one or more sensors 114, as shown an described above. The sensors 114 can also be embedded within the first device 110a and otherwise adapted to receive information from one or more of the process, e.g., the device 110a itself, and from a local environment of the device 110a, referred to generally as a surrounding environment.
In at least some embodiments, the controllable platform or process of the first device 110a is capable of communicating with another remote device, such as a remote server. The remote server can be configured as a remote monitor, e.g., adapted to send instructions to the controllable platform or process and/or to monitor processing and/or mission progress of the first device 110a.
One or more of a controller or the controllable platform or process of the first device 110a can be adapted to contain sensitive information, referred to generally as sensitive technology. It is understood that such sensitive technology should remain confidential, even if one or more of the controller or the controllable platform or process were to fall into the hands of an unintended recipient. Thus, the sensitive technology should not be maintained in an unprotected state for any substantial period of time. In at least some embodiments, such sensitive information is encrypted or otherwise obfuscated until needed, in preparation for, during, or after completion of a mission.
A particular challenge addressed by the techniques disclosed herein is that the controllable platform or process of the first device 110a can communicate with a second device 110b, such as the remote monitor before, during or after a given mission. In at least some embodiments, the second device 110b is configured similar to the first device 110b, understanding that one or more of the operating system, application programs or data structures may differ from the first device 110a, as a matter of course.
Communications between a controllable platform or process of the first device 110a and one or more of the remote monitor or a remote controller of the second device 110b can occur on any suitable communication mode, such as the communication channel 108 of
Any of these communication modes can be used alone or in combination with others. It is understood that one or more components of such communication channels 108 or modes can be unguarded, e.g., public, thereby introducing a risk that the controllable platform or process can be monitored or even taken over by unintended entities or individuals. Under such circumstances, it is likely that any sensitive technology embedded in one or more of the controllable platform or process or the remote controller or monitor can be accessed without proper authorization or otherwise stolen. Such a compromise would likely jeopardize a mission. Even worse, a capture of the controllable platform or process might allow it to be used by an adversary, a competitor, or a disturbing party for nefarious purposes, such as an attack on one's business, or physical premises, including targets both military and civilian.
According to the policy-driven techniques disclosed herein to protect such computing environments from compromise, any embedded sensitive technology as might otherwise be obtained by capture and reverse engineering can be protected. One such approach includes installation of one or more of the operating system 118 and software 120 nearly simultaneously on both the controllable platform or process and the controller. Such operating system and other software can be provided from a remote source prior to start of mission. In particular, such remote provisioning of operating systems and other software can be accomplished just-in-time with respect to a mission.
Anticipating missions with multiple phases, it is understood that one or more of the operating systems 118 and other software 120 can be installed on one or more of the controllable platform or process of the first device 110a, or the controller of the second device 110b prior to, e.g., just-in-time, with respect to a particular phase of a mission. Thus, a control system including a mission profile having a preliminary phase and a terminal phase may load one or more of the operating system 118 and other software 120 related to the initial phase just prior to the initial phase, without necessarily loading one or more of the operating system 118 and other software 120 related to the terminal phase. In the illustrative example, one or more of the operating system and the other software related to the terminal phase can be loaded during execution of, and/or after completion of the initial phase.
At least some of the techniques disclosed herein include the use of agent technology. Such agent technology can be used, e.g., to examine a controllable platform or process and a remote controller before installation of protection software and application software. In at least some embodiments, such agent technology can be used to provide continued examination of one or more of the controllable platform or process of the first device 110a or the remote controller of the second device 110b, while one or more mission applications on one or more of the controllable platform or process of the first device 110a, or the remote controller of the second device 110b are executing.
In some cases, the intelligent software agents operate entirely at the software level. In other cases, the intelligent software agents interact with hardware, such as physical sensors. Examples of sensors include, without limitation, one or more of environmental sensors, biological sensors, and more generally physical sensors and/or software sensors or monitors used to monitor application. The software or sensors that can detection values from the mission scenario, software and sensors that can detect unique characteristics of the hardware environment to prevent software from being executed in a falsified virtual environment, Environmental sensors include, without limitation, temperature sensors, humidity sensors, light sensors, position sensors, orientation sensors, altitude sensors, and motion sensors including one or more of speed or acceleration. Biological sensors include, without limitation, blood pressure sensors, blood oximeter sensors, electrical conductivity sensors, pulse rate sensors, image sensors, retinal scan sensors, finger print sensors, and the like. The system of installed software agents also is able to detect attacks and unauthorized activity. The software agents can be configured to check on one another. For example, one agent can determine if another agent is slow in responding or otherwise not available. Such indications might indicate unauthorized activity such as the presence of a debugger or an attempt to execute the software in an unauthorized environment or an attempt to execute individual software agents when the entire network of software agents is not running.
In at least some embodiments, intelligent software agents can be configured to perform collaborative tasks, e.g., by functioning in, so-called, “chains.”
In a chain, multiple intelligent software agents work together to perform a specific task. Examples of such chains are disclosed, e.g., in commonly owned U.S. Pat. No. 7,841,009, entitled “System and Method for Defending Against Reverse Engineering of Software, Firmware and Hardware,” the entire contents of which are incorporated herein by reference in its entirety. In the present disclosure, the chains of intelligent software agents are configured to include one or more functions 105 in
Sensitive technologies, sometimes referred to as sensitive or critical technologies, e.g., depending upon a particular mission or application, can be-made very difficult to obtain by encryption with appropriate algorithms and keys. Policy can be embedded in one or more elements of the control system to examine one or more of the mission application and local environments, while the applications executes. A so-called “safe” environment can be identified by policy, such that sensitive information related to a mission or application can be conditioned upon a belief or conclusion of the environment is safe. Thus, if the examination reveals that the application is operating in a safe environment, the sensitive technology can be decrypted and executed; otherwise, the critical technology is not decrypted. If a system safety state changes from safe to unsafe as defined by the embedded policy, any unencrypted, e.g., “clear text” instances of the sensitive technology are deleted and/or otherwise destroyed. In at least some embodiments, a penalty can be imposed, e.g., in response to a determination that the system state is unsafe, so that the sensitive technology can never be decrypted. In some embodiments, this penalty can be covertly imposed, so that an adversary attempting to reverse engineer the system does not immediately realize that the task of obtaining a correct key has been rendered impossible.
The control system 200 includes a control station 208 including at least one workstation or personal computer (PC). In the illustrative example, the control station 208 includes a first PC 210a and a second PC 210b. Each of the PCs 210a, 210b includes a respective embedded operating system 212a, 212b. The first PC 210a includes at least one software agent. In the illustrative example, the first PC 210a includes a first software agent 214a and a second software agent 214b. Likewise, the second PC 210b includes a first software agent 214c and a second software agent 214d.
The control system 200 also includes a controllable platform or process 216 including a first board or module 218a and a second board or module 218b. Each of the modules 218a, 218b includes a respective embedded operating system 220a, 220b. The first module 218a includes a first software agent 214e and a second software agent 214f. Likewise, the second module 218b includes a first software agent 214g and a second software agent 214h. In the illustrative embodiment a secure environment 206 including the configuration server 204 also includes a software agent 214i, and a remote server 222 includes yet another software agent 214j.
A series of thick arrows marked Install extend from the configuration server to each of the PCs 210a, 210b of the control station 208, each of the modules or boards 218a, 218b of the controllable platform 216 and the server 222 These arrows identify that, during installation of the software agent network that protects the controlled process the configuration server 204 installs all of the software to the control station 208, the controllable platform 216 and the server 222, including the operating systems 212a, 212b, 220a, 220b and the software to implement functionality of the controllable platform 216 and the control station 208.
As with installation of all operating systems, the installation process can proceed through multiple stages, starting with installation of a temporary small operating system and proceeding through using small operating system to install the complete operating system and applications that run on it. However, the installation process depends on the hardware and the circumstances and the policy as to whether everything should be installed.
As with installation of operating systems, installation of networks of software agents can also proceed through several stages, which involve initial examination of the respective environment (e.g., each of the control station environment and the controllable platform environment), running a special software agent network designed to develop cryptographic keys according to sensory information obtained from the respective environments and mission scenario (e.g., speed and/or location of the controllable platform during each phase of the mission). In the illustrative example, a network of software agents 214a, 214b, 214c, 214d, 214e, 214f, 214g, 214h, 214i, 214j (generally 214) is installed and configured along with operating systems 212a, 212b, 220a, 220b and application software for the respective target environments.
In the illustrative example, the second software agent network 254 can be used to initialize or otherwise install software 256a on the first PC 210a, software 256b on the second PC 210b, software 258a on the first module 218a and software 258b on the second module 218b. Installation of the software, according to the techniques disclosed herein can include one or more of generation of encryption keys, or installation and/or execution of the software by way of the software agent network 254 according to the predetermined policy and/or configuration information.
The area of applicability concerns policy-driven protection of computing environments which consist of a controlled process and a controller. Such environments can include industrial processes and their controllers, automobile and remote controllers that communicate with the automobiles over the Internet; modern piloted airplane software that communicates with a remote controller, and military and civilian unpiloted aircraft.
Generally speaking, the techniques disclosed herein refer to a generic design for a network of software agents in which some software agents are installed on a platform (e.g., drone, automobile, aircraft) or a controlled process; whereas, some are installed on a controller used in control of the platform. In at least some embodiments such installation occurs within a relatively short period of time, referred to as a time delay threshold. An example time delay threshold can be measured in seconds, or perhaps minutes, but generally not more than a few hours. In at least some embodiments, the software agents are installed automatically, and “right before” or “just in time” before” a “mission,” that is an occasion when the controller will be used to control the controllable platform or process.
According to the techniques disclosed herein, the agent technology can be used in various commercial and military scenarios to provide frequent software installation in a manner that would provide a very powerful level of security that is otherwise unobtainable. By way of example, the Android® operating system user community admits that completely reinstalling all software on a device provides very powerful security. See, e.g., online information available at www.windowsreinstallguide.com and www.droidlessons.com/how-to-factory-reset-your-android-device.
However, the commercial community in its software installation activities often operates under several severely restrictive conditions that might not be present in a certain commercial contexts and military contexts. In the commercial community, at least in the consumer electronics community, there is a requirement to preserve a customer's personal data, which is the reason that a complete reinstallation is an infrequent and cumbersome occurrence. The customer generally backs up his or her data before a reinstallation—a tedious procedure that subjects the customer to a significant inconvenience. A remote re-installer that attempts a backup of customer data, would require the re-installer to distinguish between legitimate customer data and hidden malware, which is very difficult. It would also defeat a major purpose of the reinstallation, which is to remove, with a high level of certain, all hidden malware.
In a military context, a drone might have surveillance data that was gathered during a mission, which will be removed after a mission (or communicated to the monitor during the course of the mission in many cases) and analyzed. But the drone has no “personal” data apart from its known mission data. Consequently, a drone could be reimaged after a mission, assuming that the equipment and procedures were available to do so, and that proper security procedures were available. Thus, the personal data protection restriction does not apply. Similarly, many industrial processes can transfer their important data to a remote server and afterward have no personal data that cannot be overwritten. These processes can be wiped clean and reimaged. Thus, software, e.g., including operating systems, can be re-installed or otherwise re-imaged on a periodic basis, e.g., daily or weekly.
If just-in-time installation is feasible in a particular context, the techniques disclosed herein can be used to install a network of software agents throughout the system, while at the same time reinstalling all or some of the operational software for the underlying system.
Consequently, a generic system, such as shown in
The software agents 214, 254 initialize secure communication channels with one another and check out the environments in which they have been installed, both during the installation process and when the controller and controlled process are operating. The software agents 214, 254 also communicate with the underlying application software 256a, 256b, 258a, 258b and provide sensitive technology to the underlying software applications if the environment and the scenario are determined to be “safe”, e.g., as defined in the policy developed by the system design team and installed in the network of software agents 214, 254.
It is envisioned that the entire procedure that could be accomplished in perhaps an hour or two, or less, depending on the complexity of the target controller and controlled process.
At least some advantages of the techniques disclosed herein include that the controlled process and the controller contain only software provided from the development environment, just-in-time for this mission. All software agents 214, 254 (and other elements that communicate over the network) could have cryptographic keys to communicate with one another that have just been installed, so that initial communication would not require any sort of asymmetric key exchange.
Inappropriate software that might have been downloaded, e.g., from the Internet by one or more of the control station 208 and the controllable platform 216, would be removed. Malware and root kits that might have loaded onto the control station 208 and the controllable platform 216 would necessarily be removed. The installation would occur automatically from the development environment based on a network definition file, so there would be minimal opportunity for malicious interference or careless error.
Depending on the circumstances, the network of software agents 214, 254 could be deleted after installation. In this use, the network of software agents 214, 254 would assure a secure complete reimaging of the target system. Alternatively or in addition, the network of software agents 214, 254 could be used as an anti-tamper system and provide protection of the sensitive technology located on the system by making available the sensitive technology when required if the system 200 is in a “safe” state, “safe” being defined by the file definition used to create the network. Additionally, the network of software agents 214, 254 can be configured to destroy the sensitive technology if the environment changes, e.g., from a “safe” state to an “unsafe” state. Alternatively or in addition, the network of software agents 214, 254 can be configured to effectively “poison” the system so that the sensitive technology can never be recovered if the environment becomes unsafe. Still further, the techniques disclosed herein can be used to defend the sensitive technology in circumstances in which the controllable platform 216 has lost communication with the control station 208 (e.g., is operating autonomously) and the environment then becomes “unsafe.”
In at least some embodiments, remote installation of an operating system, a network of software agents, and additional software, uses standard installation methods supplemented by additional procedures disclosed herein. Standard installation methods for installation of operating system kernels such as are found in Linux® and VxWorks® and supporting file systems are readily available and can be accomplished over the wire, although they are complex. A slightly different approach available in at least some embodiments is to use one or more of an existing kernel and an existing file system already resident or otherwise available on the target platform or media.
Whether an entirely new kernel and file system are installed, or existing file system and kernel are used, the installation can be configured to verify that the kernel and the file system are authentic and genuine. For example, the elements of the target installation can be examined by using procedures to hash appropriate software and to examine hardware elements such as hardware IDs, the bios, and the disk IDs. The installation procedure can be secured further if the installing programs know in advance the correct hashes of one or more of the kernel and the file system and the hardware IDs on the target media. Confirmation of by way of such hash comparisons can provide at least some measure of assurance that the kernel and file system as well as the hardware IDs on the target media have not been tampered with.
If a controlled process is running VxWorks, and the software is written in kernel mode, all software for the controllable platform would be installed according to the system illustrated in
Referring again to
The network definition file 232 implies that the software agent network 214 to be installed, and the characteristics of the target environment, including the IP addresses, are known in advance, and that the network to be built matches this definition. An option is to build another preliminary agent network to examine the target system 208, 216, to then use the information collected by the software agents to construct the network definition file 232, and then use the network definition file 232 to build the installed agent network 214.
One or more of the software agent network disclosed herein can be implemented in a chained configuration. A chained software agent network includes several software agents collaborating to conduct a common function. While information is traversing the software agents of a chain, the software agents in the chain can be configured to run various functions to examine the system. Examination of the system can include examination of sensory input, process status, and status of one or more of the software agents themselves. In at least some embodiments, chains of software agents are used to generate encryption and/or decryption key material, e.g., resulting from examinations conducted by software agents of the chain. For example, respective fragments of key material determined by each software agent of the chain can be combined to produce a key. If the examinations performed by the software agents fall within a predetermined or otherwise established range, the resulting key can be used decrypt its target object; otherwise, despite the key being generated, the resulting key will not decrypt the target object. The target object can be sensitive technology embedded within an installed artifact or it can be a target object designed to test whether the system is in certain state.
It is understood that multiple chains can be created to perform different cryptographic or examination functions in a cooperative manner in order to obtain a key. Such cooperative approaches can include logical combinations of one or more individual chains, such that a desired result, e.g., generation of a successful key, is obtained only when each of the chains produces a respective result that when combined according to the logic results in the desired result.
Thus, functions can be written by system designer following appropriate format rules or written by programmers to achieve certain objectives. The ranges of successful performance of the functions are specified by the system designers. The functions, the chains, the software agents which composed the chains, and the functions a specific agent executes within a specific chain can all defined or identified by the network definition file 232.
The design of a software agent network can be different for each system and can also depend on one or more of the functionality of the target system or the decisions of the system designer with respect to sensitive technology protection and the functions that the network of software agents is to perform. Using the techniques disclosed herein, it is possible to design a network of software agents that will make the sensitive technology available in an unencrypted fashion only if the system is in a predefined state as pre-chosen by the system designer during a design phase, generally conducted in a secure environment 202.
Using the techniques disclosed herein, it is also possible to continue to examine the control system and to destroy the unprotected instances of the sensitive technology should the system state change from a safe state to an unsafe state.
The procedure described in
Multiple instances of sensitive technology can be protected in this fashion using multiple chains which will produce different keys for each instance. It is also possible to produce functions or code fragments which can be passed from agent to agent so that the function or fragment is sent from one agent and executes on another agent. This technique can be used to examine a target execution environment by running software on the target that has never before appeared on the target. This technique can be used to examine the target during the installation process when the sending agent would be the agent 214j on the server 222 (
The network of software agents 214, 254 can conduct examinations of the system state and optionally, at the request of the system designer, can impose a penalty so that the critical technology can never be decrypted. If the change in system state is discovered before an adversary has been able to copy the entire system to a virtualized environment, the penalty can be imposed on cryptographic material that is stored in a non-volatile medium on the system hardware. If the adversary has successfully copied the system to another medium, the penalty can be imposed within the copied artifacts. The penalty should be imposed covertly so that the adversary will not realize that the penalty has been imposed and will continue to experiment with the abstracted system rather than refreshing it. The strategy of always producing a key, even if the key does not correctly decrypt, hides from the adversary whether a penalty has already been imposed and hopefully will require the adversary to engage in months or years of fruitless reverse engineering effort.
The network definition file can be utilized to define blocks of data, such as randomly generated data that are installed into artifacts that make up the network of angels that will run on the target system. These blocks of data can be used to provide session keys that are used for initial communications among the angels and also to produce longer keys that can be used to encrypt communications among the angels. Any of the keys produced according to the techniques disclosed herein could be used to perturb blocks of installed random data so as to produce longer keys to encrypt and decrypt the critical technology.
In at least some embodiments, a determination is made at 318 whether a system update should be determined. In response to concluding that a system update should be determined, the process is directed to 310, in which an updated state of the system and/or environment is determined at 310, and so forth.
Alternatively or in addition, a determination can be made at 320 whether the software agents of the initialized network of software agents should be updated. To the extent that it is determined to update the software agents, the process 300 is directed to 304, in which new and/or updated software agents are received. The process continues from 304 as described above, instead using the new and/or updated software agents.
In at least some embodiments, a determination is made at 518 (shown in phantom) whether a system update should be determined. In response to concluding that a system update should be determined, the process is directed to 510, in which an updated state of the system and/or environment is determined at 510, and so forth.
Alternatively or in addition, a determination can be made at 520 (also shown in phantom) whether the software agents of the initialized network of software agents should be updated. To the extent that it is determined to update the software agents, the process 500 is directed to 502, in which the policy is implemented. The process continues from 502 as described above, instead using the new and/or updated software agents.
The machine may comprise a server computer, a client user computer, a personal computer (PC), a tablet PC, a smart phone, a laptop computer, a desktop computer, a control system, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. It will be understood that a communication device of the subject disclosure includes broadly any electronic device that provides voice, video or data communication. Further, while a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methods discussed herein.
The computer system 600 may include a processor (or controller) 602 (e.g., a central processing unit (CPU), a graphics processing unit (GPU, or both), a main memory 604 and a static memory 606, which communicate with each other via a bus 608. The computer system 600 may further include a display unit 610 (e.g., a liquid crystal display (LCD), a flat panel, or a solid state display. The computer system 600 may include an input device 612 (e.g., a keyboard), a cursor control device 614 (e.g., a mouse), a disk drive unit 616, a signal generation device 618 (e.g., a speaker or remote control) and a network interface device 620. In distributed environments, the embodiments described in the subject disclosure can be adapted to utilize multiple display units 610 controlled by two or more computer systems 600. In this configuration, presentations described by the subject disclosure may in part be shown in a first of the display units 610, while the remaining portion is presented in a second of the display units 610.
The disk drive unit 616 may include a tangible computer-readable storage medium 622 on which is stored one or more sets of instructions (e.g., software 624) embodying any one or more of the methods or functions described herein, including those methods illustrated above. The instructions 624 may also reside, completely or at least partially, within the main memory 604, the static memory 606, and/or within the processor 602 during execution thereof by the computer system 600. The main memory 604 and the processor 602 also may constitute tangible computer-readable storage media.
There are several exemplary scenarios in which the technology may be implemented. In a first scenario, a wireless device or devices (i.e., “remote nodes”) may be attached to or embedded in shipping containers. The remote nodes may couple by wired or wireless means to various detectors configured, for example, to detect weapons of mass destruction. The detectors can be located inside the container and distributed as needed to adequately perform their surveillance functions. The detectors can be packaged with remote nodes or external to the remote nodes. The remote nodes are queried by appropriate external monitor systems to determine if the nodes and detectors have sensed weapons of mass destruction or other contraband. One issue to be confronted in such a scenario is that an enemy might attempt to sabotage or reverse engineer the nodes so that they falsely report a safe status, so that the container would pass query by authorities. This scenario is referred to as the shipping container scenario.
In another scenario, wireless remote nodes may be attached to soldiers so that these nodes can be queried on the battlefield to determine whether a person is friend or foe. One issue here is that an enemy might capture the soldiers or the equipment and reverse engineer the wireless remote node, thereby allowing the enemy to masquerade as a friend. Conversely, friendly forces might mistakenly consider a soldier on the battlefield who cannot be authenticated to be the enemy and open fire. This scenario is referred to as the soldier scenario.
In yet another scenario, wireless remote nodes may be attached to equipment such as tanks or airplanes. In such a case, the remote nodes can be queried on the battlefield to determine whether the vehicle is friend or foe. This scenario is referred to as the vehicle scenario.
In still another scenario, wireless remote nodes may be attached to individuals so that the individuals can gain authorized access to a building or an event. An issue to be confronted is that an enemy may capture an authorized individual, reverse engineer the remote node, and gain unauthorized admission. This scenario is referred to as the pass holder scenario.
In each scenario above, the wireless remote node passes through the following stages:
(1) A secure stage or stages, where the wireless remote node will be securely provided with cryptographic material.
(2) An insecure stage, where the wireless remote node will be subject to attack by an enemy.
(3) A stage where the wireless remote node will be able to detect an attack by an enemy.
(4) A stage where the wireless remote node will be queried by an external responsible agent (e.g., military or civilian authorities).
Provided in accordance with one aspect of the technology, is the ability to detect in stage (4) if an enemy attack has occurred in stage (3). This goal could be achieved by providing in stage (4) a measure of the probability that an attack has or has not occurred in stage (3). An additional goal in the soldier and vehicle scenarios is to positively identify an unknown person or vehicle as friend or foe. Table 1 shows, for each scenario, a set of secure stages and a corresponding set of attack detection approaches, as examples.
Shipping Container Scenario. Each shipping container would contain one or more wireless remote nodes that is configured to communicate internally with one another and externally with other nodes. The remote nodes would include an interface to facilitate coupling to various sensors disposed to detect the presence of illegal conditions within the container. Such detectors could, for example, be embedded in or attached to the container, as could be the remote nodes. In addition to sensing the presence of illegal conditions, the sensors could be configured to detect access to the container, whether authorized or unauthorized. Illegal conditions could be the presence of anyone or more of dangerous chemicals, biological agents or radioactive materials, explosives, drugs, or the like.
The shipping container will at various times be in facilities that are relatively secure, such as the manufacturing plant or a US Port or US controlled facility. At these times, the remote nodes can be securely provided with cryptographic materials via the Secure Network.
The wireless devices would detect an attack when they sensed prohibited substances or when an individual device sensed that it was being attacked. Several remote nodes could also continually monitor one another inside the container. Adjacent containers could also monitor one another.
Soldier Scenario. The soldier will have a wireless device connected to a body sensor. An attack will be sensed when reports from the body sensor indicate that something is amiss or when the body sensor is removed. A soldier can include a soldier, an airman or any person that formally participates in military missions. Prevention of friendly fire instances is an important goal of the soldier wireless device.
The soldier is in a relatively secure environment in the squad room before leaving for a mission and on the battlefield in the visual presence of other soldiers. At these times, the soldier can be provided with cryptographic material using Secure Network methodologies.
Military Vehicle or Airplane Scenario. The number of friendly fire instances in the Iraq war indicates the need for methods of securely identifying unknown vehicles and aircraft.
The technique in the present disclosure involves remotely auditing the remote vehicle by executing code on the remote vehicle that has been introduced over the communication channel just before execution.
This technique also can be applied to remote computing environments that are not located in vehicles.
The process that manages a node can do other things. For example, database servers can be nodes. A process that runs a browser can be a node. Intermediary routers that are used in a massive Secure Network can be nodes, including a massively scalable secure network, e.g., having 27 different nodes, with each node having a different number.
The above described techniques can be implemented in a distributed computing system that includes a back-end component. The back-end component can, for example, be a data server, a middleware component, and/or an application server. The above described techniques can be implemented in a distributing computing system that includes a front-end component. The front-end component can, for example, be a client computer having a graphical user interface, a Web browser through which a user can interact with an example implementation, and/or other graphical user interfaces for a transmitting device. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (LAN), a wide area network (WAN), the Internet, wired networks, and/or wireless networks.
The system can include clients and servers. A client and a server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
Packet-based networks can include, for example, the Internet, a carrier internet protocol (IP) network (e.g., local area network (LAN), wide area network (WAN), campus area network (CAN), metropolitan area network (MAN), home area network (HAN)), a private IP network, an IP private branch exchange (IPBX), a wireless network (e.g., radio access network (RAN), 802.11 network, 802.16 network, general packet radio service (GPRS) network, HiperLAN), and/or other packet-based networks. Circuit-based networks can include, for example, the public switched telephone network (PSTN), a private branch exchange (PBX), a wireless network (e.g., RAN, Bluetooth, code-division multiple access (CDMA) network, time division multiple access (TD MA) network, global system for mobile communications (GSM) network), and/or other circuit-based networks.
The transmitting device can include, for example, a computer, a computer with a browser device, a telephone, an IP phone, a mobile device (e.g., cellular phone, personal digital assistant (PDA) device, laptop computer, electronic mail device), and/or other communication devices. The browser device includes, for example, a computer (e.g., desktop computer, laptop computer) with a World Wide Web browser (e.g., Microsoft® Internet Explorer® available from Microsoft Corporation, Mozilla® Firefox available from Mozilla Corporation). The mobile computing device includes, for example, a Blackberry®.

It is further noted that a computing device such as a processor, a controller, a state machine or other suitable device for executing instructions to perform operations on a controllable device may perform such operations on the controllable device directly or indirectly by way of an intermediate device directed by the computing device.
While the tangible computer-readable storage medium 622 is shown in an example embodiment to be a single medium, the term “tangible computer-readable storage medium” should be taken to include a single medium, or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions.
