<p>A method for realizing an authentication center (AC) and an authentication system are disclosed. The method comprises: a UE sends an authentication request to an AC and applies for temporary authentication information, the AC assigns a first authentication random code to the UE, then the UE calculates a first response code and sends it to the AC, the AC assigns the temporary authentication information to the UE after authentication and authorization; the UE sends a login request to the application system (AS) which assigns a second authentication random code to the UE, and the UE uses it and the temporary authentication information to calculate a second response code, and sends this code to the AS; the AS sends the second response code to the AC for authentication and authorization; the AC returns the authentication result to the AS which in turn returns the authentication result to the UE. Since the temporary authentication information is featured with uniqueness and timeliness, it has enough security, thus the present invention can be widely applied in the field of authentication.</p> |
