Abstract
A message authentication and communication method for a communication network system comprises: the access control device receiving a communication establishment request sent by the first mobile apparatus; the access control device sending a communication mutual authentication request to the authentication server in response to the communication establishment request; the access control device receiving a mutual authentication response message sent by the authentication server in response to the communication mutual authentication request; the access control device authenticating the mutual authentication response message; when the mutual authentication response message is authenticated successfully, the access control device sending a mutual authentication message to the first mobile apparatus. And the hash chain mechanism and the access control device are used in conjunction with the authentication server to implement the distribution and decentralization of authentication functions, thereby reducing the load of the authentication server and improving the efficiency of authentication.
