Abstract

See full text

Systems and methods provide validation of hardware components of an IHS (Information Handling System). An attestation certificate stored to the IHS specifies authenticated instructions for operation of a hardware component of the IHS. This attestation certificate is endorsed by a self-signed root attestation certificate. An identity certificate, also stored to the IHS, specifies an identity of the hardware component and is endorsed using an embedded keypair of the hardware component. The root attestation certificate is validated to ensure it corresponds to the hardware component specified in the identity certificate, where this validation confirms that a public key included in the identity certificate is identical to a public key included in the attestation certificate. Through use of the same public key by both certificates, the attestation certificate can be validated as corresponding to the identity certificate without accessing the embedded keypair of the hardware component used to sign the identity certificate.
