  • Multi-function printing device
    Patent number: 7890772
    Abstract: A document processing device configured to communicate with a first device and a user input device. The document processing device includes a controller having memory. The controller is operable to receive a first communication from the first device. The first communication includes a job to be processed by the printing device and a first shortcut access code associated with the job. The first shortcut access code is stored in the memory of the controller. The controller is also operable to receive a second communication from the user input device. The second communication includes a second shortcut access code. The controller holds the job to be processed until the controller receives the second communication and verifies the second shortcut access code matches the first shortcut access code.

  • Abstracting security policy from, and transforming to, native representations of access check mechanisms
    Patent number: 7882539
    Abstract: Abstracting access control policy from access check mechanisms allows for richer expression of policy, using a declarative model with semantics, than what is permitted by the access check mechanisms. Further, abstracting access control policy allows for uniform expression of policy across multiple access check mechanisms. Proof-like reasons for any access query are provided, such as who has access to what resource, built from the policy statements themselves, independent of the access check mechanism that provide access. Access is audited and policy-based reasons for access are provided based on the access control policy.

  • Method and apparatus for dynamic, seamless security in communication protocols
    Patent number: 7865717
    Abstract: Communication nodes, acting as intermediate routers for communication packets transmitted between a source node and a destination node, are provided with different access rights to the fields of the routed communication packets. Routes of intermediate routers between the source node and the destination node are discovered and the identities of intermediate routers on the discovered routes are collected. The aggregate trust levels of the intermediate routers are computed allowing the most trusted route to be selected. Encryption keys are securely distributed to intermediate routers on the most trusted route based on the trust level of the intermediate routers and fields of the communication packets are encrypted with encryption keys corresponding to the assigned trust level. Intermediated nodes are thereby prevented from accessing selected fields of the communication packets.

  • Authenticating computed results in a public distributed computing environment
    Patent number: 7827596
    Abstract: An apparatus and method authenticate computed results in a public distributed computing environment without the need for fully recomputing the results. The work unit is operated on by client code that computes one or more partial results along with the completed result. When the results are returned to the server, the server may decide to have a trusted computer system process the same work unit to compute the partial result according to a defined acceptance policy. In addition, the work unit name, user identity and current date are encrypted using a time-sensitive key. Should the server detect a problem with the results (e.g., decrypted work unit name does not match, recomputed partial result does not match), the results may be rejected according to a defined rejection policy. In this manner, it becomes very difficult to fool a server into thinking a work unit has been processed when it has not.

  • Methods and systems for network traffic security
    Patent number: 7818805
    Abstract: The present invention is directed to methods of and systems for adaptive networking that monitors a network resource of a network. The method monitors an application performance. The method categorizes a first subset of traffic of the network. The categories for the first subset include trusted, known to be bad, and suspect. The method determines an action for a second subset of traffic based on the category for the first subset of traffic. Some embodiments provide a system for adaptive networking that includes a first device and traffic that has a first subset and a second subset. The system also includes a first resource and a second resource for the transmission of the traffic. The first device receives the traffic and categorizes the traffic into the first and second subsets. The first device assigns the first subset to the first resource.

  • Method and apparatus for generating cryptographic key using biometric data
    Patent number: 7802105
    Abstract: A method of securely storing and authenticating biometric data against attacks of a third party includes encoding input biometric data, and applying a one-way function to the encoded biometric data. A first exclusive OR operation is performed to the result of the one-way function and a selected secret key. The result of the first exclusive OR operation is encoded, and a second exclusive OR operation is performed to the encoded result of the first exclusive OR operation and the encoded biometric data. The result of the second exclusive OR operation is stored. In the same manner, the biometric data is authenticated. Accordingly, the biometric data can be securely stored against the attacks of a third party by processing and storing the biometric data according to a predetermined procedure.

  • Leak-resistant cryptographic payment smartcard
    Patent number: 7792287
    Abstract: We disclose methods and apparatuses for securing cryptographic devices against attacks involving external monitoring and analysis. A “self-healing” property is introduced, enabling security to be continually re-established following partial compromises. In addition to producing useful cryptographic results, a typical leak-resistant cryptographic operation modifies or updates secret key material in a manner designed to render useless any information about the secrets that may have previously leaked from the system. Exemplary leak-proof and leak-resistant implementations are shown for symmetric authentication, certified Diffie-Hellman (when either one or both users have certificates), RSA, ElGamal public key decryption.

  • System and method for securely sharing electronic documents
    Patent number: 7784087
    Abstract: A system and method for the selective sharing of an electronic document. The method enables a user to share access to an electronic document stored on a repository on a document management system. A user, via a document processing services network, generates a password and token corresponding to the document to be shared. The token provides information regarding the electronic document to be shared and the way the shared document will be made available to other users. The user then gives the token along with the password to the other users desiring to have access to the shared document. The other users are then able to retrieve the electronic document via email, viewing on a web browser, or printing at a multifunction peripheral device.

  • One time password integration with Kerberos
    Patent number: 7757275
    Abstract: A domain controller (DC) side plugin supports one time passwords natively in Kerberos, Part of the key material is static and the other part is dynamic, thereby leveraging properties unique to each to securely support one time passwords in an operating system. The user is permitted to type in the one time passcode into a logon user interface. Rather than calling the SAM APIs to get the static passwords, vendors may register callbacks on the DC to plugin their algorithm. These callback functions will return the dynamically calculated passcodes for the user at a specific point in time. This passcode will then be treated as a normal password by the DC.
