Abstract  Abstract

authentication method used to authenticate the mobile node to the packet data network wherein the common secret by mobile node and a telecommunications network authentication centre to configure a shared secret of the mobile node and the packet data network. In this method the mobile node transmits the user identity and the replay attack protection code to the packet data network. obtaining verification code and using them to form a session key and using the session key to obtain the packet data network query and encrypted verification back to the mobile node. the mobile node can then use the inquiry form the rest of the validation code and then form the session key. using the session key the mobile node can check the validity of the encryption verification. if the verification is correct the mobile node sending the encrypted response session key to the packet data code for verification itself to a packet data network.

Authentication method for authenticating a mobile node to a packet data network in which a shared secret for both the mobile node and the packet data network is arranged by using a shared secret of the mobile node and a telecommunications network authentication centre. In the method the mobile node sends its subscriber identity to the packet data network together with a replay attack protector. The packet data network obtains authentication triplets forms a session key using them and sends back to the mobile node challenges and a cryptographic authenticator made by using the session key. The mobile node can then form the rest of the authentication triplets using the challenges and then form the session key. With the session key the mobile node can check the validity of the cryptographic authenticator. If the authenticator is correct the mobile node sends a cryptographic response formed using the session key to the packet data network for authenticating itself to the packet data network.
