Abstract
Systems and methods for secure modular hardware binding in a Data Center Modular Hardware System (DC-SCM) environment are described herein. According to one embodiment, an Information Handling System (IHS) includes multiple Complex Programmable Logic Devices (CPLDs), and computer-executable logic to, for each of the CPLDs: store an encrypted secret key in a platform Root-of-Trust (RoT) and the CPLD, and receive, by the platform RoT, a request to authenticate a firmware stack installed on the CPLD. The logic may then present, by the CPLD, an encrypted secret key to the platform RoT, authenticate, by the platform RoT, the firmware stack by comparing the encrypted secret key received from the CPLD with its stored version of the encrypted secret key, and allow operation of the CPLD based on the authentication.
