Abstract

Procédé selon lequel des informations prédéterminées sont préalablement enregistrées dans des zones de cellules de mémoire situées dans la zone de mémoire d'un circuit intégré d'une carte à circuit intégré. Ces zones de cellules de mémoire sont lues et évaluées au début d'une opération nécessitant de la sécurité. Ce n'est que lorsqu'il a été constaté qu'aucune des données, c'est-à-dire des informations prédéterminées, n'a été modifiée que l'instruction ou l'opération nécessitant de la sécurité est effectuée.
