Abstract
Techniques are provided for provisioning multiple platform root of trust (PRoT) entities using role-based identity certificates. One method comprises obtaining a designation of a PRoT entity of a hardware device as a PRoT leader associated with a leader role; recording the leader role as a role attribute in an identity certificate; and providing the identity certificate to the hardware device during a provisioning of the hardware device, wherein the given PRoT entity assumes the leader role of the hardware device and initiates security actions of the PRoT leader upon an initiation of the hardware device. Leader responsibilities can be assigned to the PRoT leader and the one or more leader responsibilities of the PRoT leader may be recorded as a leader responsibility attribute in the identity certificate.
