  • Patent number: 8434147
    Abstract: The present invention provides a computer-implemented method system and program product for remotely verifying (e.g., analytic) integrity of a system. Specifically, at startup of the system an access control policy that sets forth information flows within the system is read and a set of trusted subjects that interact with a target application in the system is determined. Based on the access information flows and the set of trusted subjects, an information flow graph of the system is constructed. At runtime of the target application, runtime information and program code loaded into the set of trusted subjects are measured. Measuring the program code that is loaded allows the remote party to verify that the program code is “expected” program code for the set of trusted subjects.

  • Patent number: 7809821
    Abstract: A solution for evaluating trust in a computer infrastructure is provided. In particular, a plurality of computing devices in the computer infrastructure evaluate one or more other computing devices in the computer infrastructure based on a set of device measurements for the other computing device(s) and a set of reference measurements. To this extent, each of the plurality of computing devices also provides a set of device measurements for processing by the other computing device(s) in the computer infrastructure.

  • Patent number: 7661033
    Abstract: A method, computer readable medium and computer system for repairing a failed network connection between a client system and a network is disclosed. In a first aspect, the method preferably includes collecting real time connectivity information by the client system and utilizing the real time connectivity information by the client system to establish a connection with the network. In a second aspect, a computer system coupled to a network includes at least one network adapter for monitoring and collecting real time connectivity information from the network, memory for storing the real time connectivity information, and a processor coupled to the memory and to the at least one network adapter, where the processor is configured to execute program instructions for utilizing the real time connectivity information to repair a failed network connection between the computer system and the network.
