METHOD AND SYSTEM FOR CLIENT AUTHENTICATION

A method by authorizing the access of a client by performing an anonymous Diffie-Hellman exchange that can produce authentication material (secret key) between the client and the server, and binding the key to the service-oriented state information asserted by the client. The secret key can be used in the future to prove the ownership of resources as outlined in the state information. This method enables resource ownership-dependent service authorization without requiring initial identity authentication.
