    Abstract: A computing device that implements a secure and transparent firmware update process is provided. The computing device includes a secure memory area and a secure device that separately executes firmware updates in parallel with other processes executed by a CPU. The secure memory area may be allocated by the CPU and/or a memory controller using any of a variety of memory protection techniques. System software executed by the CPU receives update firmware requests from a trusted source, stores a firmware payload included in these requests in the secure memory area, and executes the next scheduled process. Firmware executed by the secure device retrieves the firmware payload from the secure memory area, authenticates the firmware payload, and applies the firmware payload to a firmware storage device. The secure device performs these acts transparently from the point of view of the CPU, these avoiding consumption of resources of the CPU.

    Abstract: Technologies to enable, disable and control hardware subscription features. Computing devices communicate over a network to a subscription server to provide hardware platform information for each of the computing devices. As the subscription server receives hardware platform information, the subscription server determines the hardware features that are enabled, and further determines what hardware subscription options are available for each of the computing devices. When a hardware subscription option is selected/purchased by a computing device, subscription server provides a pre-boot update mechanism, such as a Unified Extensible Firmware Interface (UEFI) capsule, to act as a boot level program that enables hardware features on the computing device. Hardware subscription features are also securely protected using cryptographic engine modules.

    Abstract: In an embodiment, a computing device may include a memory device that may be rendered unusable after a certain number of operations are performed on the memory device. The computing device may incorporate one or more techniques for protecting the memory device. Processing logic contained in the computing device may be configured to implement the techniques. The techniques may include, for example, acquiring a request to write or erase information stored in a memory device contained in a first computing device, saving the request for execution after a user visible event has been generated on the first computing device, generating the user visible event on the first computing device, and executing the saved request after the user visible event has been generated. In addition, the techniques may include reporting the request. The request may be reported to, for example, an anti-malware agent.
