ABSTRACT:
The present invention provides an authentication method and apparatus for authenticating an identity of a subscriber attached to a network. According to the invention, in a network terminal, a subscriber identity module is used so that a response is obtained as a result of a challenge given to the identity module as input. A special security server in the network is also used so that when a terminal attaches to the network, a message of a new user is transmitted to the security server. Subscriber authentication information corresponding to the new user is fetched from the mobile communications system to the network, wherein the authentication information includes at least a challenge and a response. Authentication is performed based on the authentication information obtained from the mobile communications system by transmitting the challenge to the terminal through the network, by checking at the terminal that the challenging is unique from challenges used in previous authentication exchanges, by generating, if the challenge is unique, a response from the challenge in the identity module of the terminal and by comparing the generated response with the response received from the mobile communications system.
