Abstract: Both end-to-end security and traffic visibility may be achieved by a system using a controller that derives a cryptographic key that is different for each client based on a derivation key and a client identifier that is conveyed in each data packet. The controller distributes the derivation key to information technology monitoring devices and a server to provide traffic visibility. For large key sizes, the key may be derived using a derivation formula as follows: client_key_MSB=AES128(base_key_1,client_ID),??(1) client_key_LSB=AES128(base_key_2,client_ID+pad),and??(2) client_key=client_key_MSB?client_key_LSB, where (1) and (2) are executed in parallel. The client key and a client identifier may be used so that end-to-end security may be achieved.

Abstract: Systems and methods of conducting collaborative sessions between mobile devices may provide for determining a time delay associated with a set of participating mobile devices, and determining a command execution time based at least in part on a clock of a managing device and the time delay. One or more control messages may be transmitted to the participating mobile devices, wherein the control messages include the command and the command execution time. Upon receiving a control message, each participating mobile device may determine a local execution time based at least in part on the command execution time and an offset of the clock of the managing device relative to a local clock. Execution of the command can therefore be coordinated across the set of participating mobile devices.

Abstract: Methods for anonymous authentication and key exchange are presented. In one embodiment, a method includes initiating a two-way mutual authentication between a device and a remote entity. The device remains anonymous to the remote entity after performing the authentication. The method also includes establishing a mutually shared session key for use in secure communication, wherein the initiating and the establishing are in conjunction with direct anonymous attestation (DAA).

Abstract: In an embodiment a software application may include a “baseline trace” indicating proper application execution. The baseline trace may include counts for various types of instructions (e.g., how many times each of a LR instruction and a MV instruction occurs during an execution of code). The finished application includes the baseline trace. Upon execution the application randomly selects which of the various types of instructions to count during execution (e.g., LR or MV instruction) to produce a “real time trace”. The application executes and produces the real-time trace. The baseline trace is then compared to the real-time trace, which is specific to the randomly chosen type of instruction. If the traces are within a pre-determined range of each other the user has a level of assurance the software is operating correctly. Other embodiments are described herein.

Abstract: An embodiment provides a level of assurance regarding correct operation of software. An embodiment creates baseline and real-time measurements of software and compares the measurements to determine whether the software is operating correctly. An application provider may include “tracing elements” in target software application. While producing the application the trace elements are detected and provide trace events, which collectively provide a “baseline trace” indicating proper application execution. The provider supplies the application and the baseline trace to a user. The user operates the application in real-time to produce a “real-time trace” based on the application still having trace elements that produce trace events (which collectively form the “real-time” trace). A comparator compares the baseline and real-time traces. If the traces are within a pre-determined range of each other the user has a level of assurance the software is operating correctly. Other embodiments are included herein.

Abstract: In an embodiment of the invention an application provider may include “tracing elements” in a target software application. While working with the application the trace elements are detected and provide a “baseline trace” indicating proper application execution. The provider then supplies the application, which still includes the trace elements, and the baseline trace to a user. The user operates the application to produce a “real-time trace” based on the application still having trace elements that produce trace events. A comparator then compares the baseline and real-time traces. If the traces are within a pre-determined range of each other the user has a level of assurance the software is operating correctly. If the level of assurance is low, an embodiment may trigger a hardware interrupt or similar event to prevent further execution of software. Other embodiments are described herein.
