1. A non-transitory computer-readable medium storing instructions that, when executed by a host computing device, cause the host computing device to:
derive, from a direct anonymous attestation (DAA) credential, a base name point; provide, to a trusted platform module embedded on the host computing device, a message and the base name point, the trusted platform module including computer storage for protecting security of a public key value associated with the base name point; receive, from the trusted platform module, a version of the message signed by the trusted platform module using the base name point, wherein the version of the message includes the public key value; and determine, based on the version of the message signed by the trusted platform module and the base name point, whether the DAA credential is valid. |
