Abstract

An apparatus to verify firmware in a computing system, comprising a non-volatile memory, including firmware memory to store agent firmware associated with each of a plurality of interconnect protocol (IP) agents and version memory to store security version numbers (SVNs) included in the agent firmware, a security controller comprising verifier logic to verify an integrity of the version memory by applying a hash algorithm to contents of the version memory to generate a SVN hash, and a trusted platform module (TPM) to store the SVN hash.
