Abstract

Dans un procédé assurant des services de protection contre la copie sur un support mémoire, les emplacements où sont stockées les données, qui sont de préférence arrangées sous forme de blocs, sont sélectionnés par un dispositif de commande (lui-même intégré) sur une base aléatoire. Le fait d'utiliser une clé de chiffrement qui dépend nécessairement de la position des données sur le support mémoire rend virtuellement impossible le déchiffrement des données copiées.
