Methods and apparatus for generating endorsement credentials for software-based security coprocessors

摘要

A virtual manufacturer authority is launched in a protected portion of a processing system. A key for the virtual manufacturer authority is created. The key is protected by a security coprocessor of the processing system, such as a trusted platform module (TPM). Also, the key is bound to a current state of the virtual manufacturer authority. A virtual security coprocessor is created in the processing system. A delegation request is transmitted from the processing system to an external processing system, such as a certificate authority (CA). After transmission of the delegation request, the key is used to attest to trustworthiness of the virtual security coprocessor. Other embodiments are described and claimed.
