Abstract

A SIM card (6) for mobile telephony in a first stage is inserted into its memory with unique information including a unique identity in order to effect telephony with a mobile telephone. A memory on the SIM card in another stage is provided with partly the first (S-key) and second (O-key) encoding key and partly the encoding algorithm. - The first encoding key is secret and the second (O-key) is open. A system to which information is to be transmitted is provided with the second encoding key coupled to an identity in the SIM card. The mobile telephone receives information concerning the transmitter open encoding key and stores it in a memory on the SIM card when the mobile telephone is to receive encoded information from the transmitter. After inserting the SIM card in a mobile telephone and feeding in a PIN code on the mobile telephone (1) keyboard (2), a microprocessor (7) on the SIM card carries out an encoding of an information stored in a memory on the SIM card in accordance with a selected encoding key and the encoding algorithm.
