Abstract
In one embodiment, a method of attestation involves a special mode of operation. The method comprises storing an audit log within protected memory of a platform. The audit log is a listing of data representing one or more software modules loaded into the platform. The audit log is retrieved from the protected memory in response to receiving an attestation request. Then, the retrieved audit log is digitally signed to produce a digital signature in response to the attestation request.
