Abstract
A process includes accessing by a management controller of a computer platform, a platform certificate that is stored in a secure memory. The platform certificate includes data representing a reference inventory for the computer platform. The platform certificate includes data representing information designated to bind the platform certificate to a security processor. The security processor is accessible by the management controller. The security processor is inaccessible by an operating system of the computer platform. The process includes verifying the platform certificate. Verifying the platform certificate includes validating, by the management controller, a signature of the platform certificate; and validating, by the management controller, the information designated to bind the platform certificate to the security processor. Verifying the platform certificate includes comparing, by the management controller, a second inventory of the computer platform to the reference inventory.
