Abstract

L'invention concerne un système électronique (300) comprenant un processeur hôte (305), un jeu de puces avec fonctions de chiffrement en masse (315), une mémoire principale (310), et une unité de chiffrement (335). Ce système électronique (300) comprend également un bus hôte (320), un bus à mémoire (325) et un bus (330). L'unité de chiffrement (335) comprend un ensemble de circuits destiné à commander et à gérer les opérations de chiffrement en masse qui sont réalisées par le jeu de puces (315) au moyen de clés secrètes et/ou de clés de session, au cours du processus de chiffrement.
