Abstract
A computing system includes a baseboard management controller ('BMC') that receives a security token from a management system. The computing system also executes a firmware that collects measurements from components of the computing system. The measurements include data describing the components for use in attestation. The firmware provides the measurements to the BMC, which generates a digital signature of the measurements and the security token. The BMC provides the measurements and the digital signature to the management system, which attempts to verify the digital signature utilizing a public key associated with the BMC. If the management system can verify the digital signature, then the BMC utilized the correct security key to generate the digital signature and the measurements were not tampered with after collection by the firmware. The measurements can then be utilized to attest the computing system.
