ABSTRACT:
The terminal and the user module are authenticated in a combined manner on the basis of an authentication key calculated on the one hand by the terminal and on the other hand by the network. A session key is firstly calculated by the user module on the basis of a secret user key, of a terminal identification parameter and of a first random number. Calculation of the authentication key by the terminal involves this session key calculated by the user module, a secret terminal identification key and a second random number. The network calculates in the same way the session key and the authentication key by retrieving the secret keys on the basis of the identification parameters transmitted by the terminal. The terminals can then be authenticated by the network independently of the associated user modules.
