  • Patent number: 11775634
    Abstract: Computing platform security methods and apparatus are disclosed. An example apparatus includes a graphics processor; and a graphics driver to facilitate access to the graphics processor, the graphics driver including: an authenticator to establish a trusted channel between the graphics driver and an application driver via mutual authentication of the graphics driver and the application driver; an offloader to offload a computing task to the graphics processor via the trusted channel, the computing task associated with the application driver; and a hypervisor to monitor memory associated with the offloaded computing task for an unauthorized access attempt.

  • Patent number: 11003584
    Abstract: A data processing system includes support for sub-page granular memory tags. The data processing system comprises at least one core, a memory controller responsive to the core, random access memory (RAM) responsive to the memory controller, and a memory protection module in the memory controller. The memory protection module enables the memory controller to use a memory tag value supplied as part of a memory address to protect data stored at a location that is based on a location value supplied as another part of the memory address. The data processing system also comprises an operating system (OS) which, when executed in the data processing system, manages swapping a page of data out of the RAM to non-volatile storage (NVS) by using a memory tag map (MTM) to apply memory tags to respective subpages within the page being swapped out. Other embodiments are described and claimed.

  • Patent number: 7280471
    Abstract: A fully automated method of providing network services on demand is disclosed. The method includes receiving a request for download traffic from a user and beginning transmission of the download traffic to the user. The user is provided with the option of requesting better service level if required for an extra cost. If the user experiences poor service quality, the user then submits a service request by simply clicking a button. The NHCC then automatically identifies the customer traffic, determines the service parameters for the download traffic. With a global view of the existing network topology and conditions, the NHCC determines if the incoming service level request can be accommodated. If the network can be provisioned to accommodate the request, the NHCC sends traffic provisioning requests to Smart Nodes. The download traffic quality then improves thereby providing the customer with better quality of service.
