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).

La présente invention concerne un système de délivrance électronique de code PIN d'une manière sûre, rapide et efficace. Ce système comprend un serveur (3) pourvu d'un code de référence (2) destiné à générer le code PIN. Ce serveur (3) est adapté de façon à transmettre à une carte SIM (10) connectée à un terminal (12) un message (9) de service de message court (SMS) contenant une signature (5) électronique fondée sur le code de référence (2). Cette carte SIM (10) comprend un organe destiné à recevoir et à mémoriser ce message (9) SMS, et un organe (17) destiné à comparer la signature (5) électronique mémorisée du message (9) SMS avec une signature (20) électronique générée par un code de référence (15) entré par un utilisateur du terminal (12). Des clés de cryptage générées par un algorithme de données DES triple à deux clés et un organe de cryptage sont présents dans le serveur (3) et dans la carte SIM (10).
