  • Patent number: 8984316
    Abstract: Secure fast platform hibernation and resumption for computing systems. An embodiment of an apparatus includes a processor to operate according to an operating system, the processor to transition the apparatus to a first reduced power state in response to a request, the transition to the first reduced power state including the processor to store context data for the apparatus in a volatile system memory, and logic to transition the apparatus to a second reduced power state, the logic to write the context data from the volatile system memory to a nonvolatile memory for the transition to the second reduced power state, wherein the logic is to implement one or more security measures for the writing of the context data into the nonvolatile memory.

  • Patent number: 8156337
    Abstract: Pre-authentication information of devices is used to securely authenticate arbitrary peer-to-peer ad-hoc interactions. In one embodiment, public key cryptography is used in the main wireless link with location-limited channels being initially used to pre-authenticate devices. Use of public keys in the pre-authentication data allows for the broadening of types of media suitable for use as location-limited channels to include, for example, audio and infrared. Also, it allows a range of key exchange protocols which can be authenticated in this manner to include most public-key-based protocols. As a result, a large range of devices, protocols can be used in various applications. Further, an eavesdropper is forced to mount an active attack on the location-limited channel itself in order to access an ad-hoc exchange. However, this results in the discovery of the eavesdropper.

  • Patent number: 7904720
    Abstract: System and method for providing secure resource management. The system includes a first device that creates a secure, shared resource space and a corresponding root certificate for the shared space. The first device associates one or more resources that it can access with the shared space. The first device invites one or more other devices to join as members of the space, and establishes secure communication channels with the devices that accept this invitation. The first device generates a member certificate for each accepting device, and sends the root certificate and the generated member certificate to the device through the secure channel. These devices may then access resources associated with the shared space by presenting their member certificates. Further, members of the shared space may invite other device to join the space, and may create member certificates in the same manner as the first device.
