Presented herein is hardware fingerprinting technology that provides the ability to detect tampered hardware using a trust anchor. During manufacturing of networking equipment (e.g., routers, switches, etc.), a manufacturer fingerprints the critical hardware elements of a platform/system, such as Central Processing Units (CPUs) and/or Application-Specific Integrated Circuits (ASICs). The fingerprint is stored in the tamper resistant trust anchor. This fingerprint is then examined at every power cycle (and possibly on-demand) to determine whether a critical component has been replaced.
