Abstract:
An exemplary apparatus includes one or more processors; memory; circuitry configured to hash a value associated with core root of trust measurement code and system management code; store the hash in a secure register; load an operating system; validate a certificate associated with the core root of trust measurement code and validate a certificate associated with the system management code; based on the validated certificates, provide an expected hash associated with the core root of trust measurement code and the system management code; decide if the expected hash matches the hash stored in the register; and, if the expected hash matches the hash stored in the register, commence a dynamic root of trust measurement session. Various other apparatuses, systems, methods, etc., are also disclosed.
