Abstract:
An apparatus to facilitate permissions at a computing system platform is disclosed. The apparatus includes a plurality of agents, each including a non-volatile memory storing firmware executed to perform a function associated with the agent and attestation hardware to detect an update at the computing system platform, generate a cryptographic key associated with each of the plurality of agents, perform an attestation with a relying party using the generated cryptographic keys and receive a tuple associated with each of the plurality of agents, wherein a tuple includes one or more permissions indicating platform resources an agent is permitted to access.
