Digital Master Key

A person uses a single device, the Master Key, which aggregates all his digital forms of access tokens for entity authentication. The Master Key discovers and selects proper tokens for its owner. With an emphasis on usability, the Master Key secures authentication, protects privacy information from outsiders and insiders, and supports various claimant-verifier relations. The Master Key authentication protocols are highly efficient.
