  • Patent number: 9313030
    Abstract: Various disclosed embodiments include methods, devices and systems establishing secure discovery and secure communication in an ad hoc information-centric network (ICN). An application in a consumer device sends a discovery interest including an associated service name or prefix encrypted by an encryption key using the ICN. A producer device publishing and discovery protocol (SPDP) on an ICN stack of the producer device receives the discovery interest and verifies the consumer device using the encryption key. The producer device SPDP returns a data protocol data unit (PDU) to the consumer device configured to enable the consumer device to access the published service, and the consumer device establishes routing with the producer device and receives the local published service.

  • Patent number: 9252942
    Abstract: One embodiment of the present invention provides a system for performing secure multiparty cloud computation. During operation, the system receives multiple encrypted datasets from multiple clients. An encrypted dataset associated with a client is encrypted from a corresponding plaintext dataset using a unique, client-specific encryption key. The system re-encrypts the multiple encrypted datasets to a target format, evaluates a function based on the re-encrypted multiple datasets to produce an evaluation outcome, and sends the evaluation outcome to the multiple clients, which are configured to cooperatively decrypt the evaluation outcome to obtain a plaintext evaluation outcome.

  • Patent number: 9246803
    Abstract: Various disclosed embodiments include methods, systems, and computer-readable media for named data network (NDN) inter/intra-domain mobility. A complete de-coupling of identity and addressing space is established. This provides separation of control and forwarding allowing rich policy based routing, using SDN principles, as well as policy based global resolution. In one embodiment, the de-coupling of identity from location is achieved by a changeable forwarding label field in a header that can have nodal/domain/global scope. This disclosure provides content routing/mobility to be handled with a high degree of flexibility. This disclosure also provides mobility as a service for a component of a name space.

  • Patent number: 9052958
    Abstract: Techniques for extending the capabilities of computing environments and/or systems are disclosed. A scalable and dynamic external computing resource can be used in order to effectively extend the internal computing capabilities of a computing environment or system. The scalable and dynamic external computing resource can provide computing resources that far exceed the internal computing resources, and provide the services as needed, and in a dynamic manner at execution time. As a result, a computing device may function with relatively limited and/or reduced computing resources (e.g., processing power, memory) but have the ability to effectively provide as much computing services as may be needed, and provide the services when needed, on demand, and dynamically during the execution time.

  • Patent number: 8924987
    Abstract: In an integrated approach, an integrated application and operating system (IAOS) component integrates at least one computer application program with at least one operating system (OS) function. The IAOS component is an upper level system relative to a lower level system. The lower level system includes an OS operable to perform a reduced set of OS functions. The OS may be optimized for the IAOS component. For example, the OS may be optimized for Web-based and/or Browser-based applications of the IAOS component. In a flat approach, at least one component is an adjacent component in an upper level system, thereby allowing extension of the upper level system to accommodate various needs. An adjacent component can include at least one OS component and/or function not provided by the OS, serve as an interface to another layer and/or the OS, or provide Real-Time Operating System.
