Abstract
La présente invention concerne un dispositif de protection des clés d'une carte à puce, caractérisé en ce que:
- chaque clé est chiffrée, a l'aide d'une clé diversifiée;
- une information de protection, correspondant à une information dépendante de chaque clé chiffrée, générée et associée à chaque clé
chiffrée;
- un moyen de détection implanté sur la carte permet de vérifier l'intégrité
de la clé, en comparant l'information de protection avec une information de vérification générée à partir de la clé de la carte, par le moyen de détection de la carte;
- un moyen de blocage permet le blocage de tout calcul ultérieur sur la clé
dans le cas où l'information de vérification n'est pas identique à
l'information de protection.
