A method of transferring information between a subscriber identification model and a mobile terminal constituting a station of a radiocommunication system in which at least some of the information transferred between said module and said terminal is protected by encryption. The subscriber identification module and the mobile terminal include encryption means using a key defined at least in part by periodically-varying data specific to the system.

Method of transferring information between a subscriber identification module and a radiocommunication mobile terminal, and a corresponding subscriber identification module and mobile terminal

A method of adapting the operation of a subscriber identity module as a function of information received from a mobile radio communications terminal concerning one or more interfaces of the mobile radio communications terminal. The subscriber identity module transmits an interface information acquisition command to the communications terminal. Upon reception of the interface information acquisition command, the terminal executes the interface information acquisition command to generate a reply containing interface information which is transmitted to the subscriber identity module. Upon reception of the reply, the subscriber identity module adapts its operation as a function of the interface information contained in the reply.
