发明名称 CRYPTOGRAPHIC IDENTITY VERIFICATION METHOD AND APPARATUS
摘要 A prover possessing public information and related secret information sends the public information and an initial message to a verifier. The verifier sends back a random message and an enquiry generated from the initial message and random message. The prover confirms that the enquiry has been correctly generated, then sends the verifier a response created from the enquiry and the secret information and related to the initial message. Using the initial message and public information, the verifier checks whether the response is a valid response to the enquiry. If it is, the verifier stores the public information, initial message, random message, and response as a transcript. If necessary, the transcript can be submitted to an arbitrator to establish that verification has taken place.
