Abstract: Embodiments related to hardware configuration reporting and arbitration are disclosed herein. For example, an apparatus for hardware configuration reporting may include: a processing device having a trusted execution environment (TEE) and a non-trusted execution environment (non-TEE); request service logic, stored in the memory, to operate within the TEE to receive an indication of a request from arbiter logic, wherein the request represents a hardware configuration register; and reporting logic, stored in the memory, to operate within the TEE and to report an indicator of a value of the hardware configuration register represented by the request to the arbiter logic. Other embodiments may be disclosed and/or claimed.

Abstract: An embodiment includes an apparatus comprising: an out-of-band cryptoprocessor coupled to secure non-volatile storage; and at least one storage medium having firmware instructions stored thereon for causing, during runtime and after an operating system for the apparatus has booted, the cryptoprocessor to (a) store a key within the secure non-volatile storage, (b) sign an object with the key, while the key is within the cryptoprocessor, to produce a signature, and (c) verify the signature. Other embodiments are described herein.
