Abstract
This application discloses a supply chain security technique that enrolls an integrated circuit with a security server and subsequently utilizes the enrollment to authenticate the integrated circuit. The integrated circuit can include security circuitry to enroll the integrated circuit with the security server by generating an enrollment message—including a fingerprint code having an encoded version of a private value generated by the security circuitry—for transmission to the security server. The security circuitry can authenticate the integrated circuit by replying to a request to verify authentication of the integrated circuit from the security server. The response can confirm to the security server that the integrated circuit includes the private value, which can authenticate the integrated circuit.
