Apparatus and method for provisioning an endorsement key certificate for a firmware trusted platform module
Abstract:
Disclosed is a method for provisioning an endorsement key (EK) certificate for a firmware trusted platform module (fTPM). In the method, the fTPM receives a derived key (DK) from a hardware trusted platform (HWTP). The fTPM is implemented in the HWTP, the DK is derived from a hardware key (HWK) securely stored in the HWTP, the HWK is unique to the HWTP, and the HWK is not available to the fTPM. The fTPM generates an endorsement primary seed (EPS) based on the DK, and generates a hashed endorsement primary seed (HEPS) based on a hash of the EPS. The fTPM forwards the HEPS to a provisioning station, and receives, from the provisioning station, an EK certificate corresponding to the HEPS.
