Abstract: An apparatus includes a solid-state a solid-state non-volatile computer memory; and a controller coupled to the memory. The controller to: generate a data set including a tag that indicates that the data set is valid; write the data set into a block of the memory, wherein the block includes multiple addressable locations set to a common first binary value before the write; generate a subsequent data set including a tag that indicates that the subsequent data set is valid; update the tag of the written data set to indicate that the written data set is invalid, wherein the update includes setting an addressable location corresponding to the tag to second binary value different from the first binary value; write the subsequent data set to addressable locations in the block of memory other than the addressable locations of the invalid data set.

Abstract: Examples of computing devices are described herein. In some examples, a computing device may include a controller to generate a key upon boot of the computing device. In some examples, the computing device may include a kernel driver. In some examples, the kernel driver may be to receive the key from a basic input/output system (BIOS) during operating system (OS) boot. In some examples, the kernel driver may be to receive an action request for a BIOS action from an application. In some examples, the kernel driver may be to sign the action request with the key in response to determining that the application is authorized to request the BIOS action. In some examples, the computing device may include the BIOS to perform the BIOS action in response to receiving the signed action request.

Abstract: In an example, apparatus is described. The apparatus comprises a processor associated with a secure interface of the apparatus for managing communications with a communications interface communicatively coupled to the secure interface via a communication path. The apparatus further comprises a non-transitory machine-readable medium storing instructions readable and executable by the processor. The instructions cause the processor to receive, via the secure interface, a request generated by a requesting entity for the apparatus to provide information about a computing system associated with the apparatus. The instructions further cause the processor to, in response to the request, produce a message comprising the information, where the message comprises an indication that the apparatus produced the message.
