<p>A system is provided for electronic delivery of a PIN code in a secure, fast and efficient manner and compromising a server (3) provided with a reference code (2) for generating the PIN code. The server (3) is adapted to transmit a SMS message (9) containing an electronic signature (5) based on the reference code (2) to a SIM card (10) connected to a terminal (12). The SIM card (10) comprises means (11) for receiving and storing the SMS message (9), and means (17) for comparing the stored electronic signature (5) in the SMS message (9) with an electronic signature (20) generated from a reference code (15) entered by a user of the terminal (12). Encryption keys, generated by a triple DES data encryption algorithm having two keys, and encryption means are provided in the server (3) and in the SIM card (10).</p> |
