  • MULTIPROCESSOR SYSTEM WITH INDEPENDENT DIRECT ACCESS TO BULK SOLID STATE MEMORY RESOURCES
    Publication number: 20190121553
    Abstract: A system has a collection of central processing units. Each central processing unit is connected to at least one other central processing unit and has a path into flash memory resources. A central processing unit supports a mapping from a data address space, to a flash memory virtual address space, to a flash memory virtual page number to a flash memory physical address space.
    Type: Application
    Filed: December 17, 2018
    Publication date: April 25, 2019

  • Attestation using a combined measurement and its constituent measurements
    Patent number: 9747450
    Abstract: An attestation system for asserting and verifying assertions of a known-good state of a computer system is provided. The attestation system allows a challenger and a prover to conduct an attestation so that the challenger can verify an assertion of the prover. To conduct the attestation, the prover sends, as an assertion of its state, a combined measurement of resources along with a constituent measurement of each resource to the challenger. The challenger verifies the assertion by verifying that the asserted constituent measurements represent known-good measurements and verifying that the asserted combined measurement can be generated from the asserted constituent measurements. To verify the asserted constituent measurements, the challenger determines whether each asserted constituent measurement for a resource is a known-good measurement for that resource.
