Abstract

Toute portion d'un code programme destinée à être copiée dans la mémoire cache (120) d'un microprocesseur (1) transite chiffrée entre la mémoire vive (6) et le processeur (1) et le déchiffrement est effectué au niveau de la mémoire cache (120). Une somme de contrôle peut être insérée dans les lignes de cache pour permettre une vérification d'intégrité et cette somme de contrôle est alors remplacée par une instruction spécifique avant délivrance d'un mot d'instruction à l'unité centrale (11) du microprocesseur (1).
