Abstract

Un appareil de chiffrement comprend des premier et second dispositifs DES à N étages (140, 160) et des premier et second circuits d'entrée inverseurs (INV2, INV1). Le premier dispositif DES à N étages (140) effectue une conversion cryptographique d'un bloc de données d'entrée numérique (D) en un premier bloc de données de sortie numérique (C), sur la base d'un jeu de clés de chiffrement (K1-K16). Le second dispositif DES à N étages (160) effectue une conversion cryptographique du bloc de données d'entrée numérique inversé (D') en un second bloc de données de sortie numérique (C'), sur la base des clés de chiffrement inversées (K1'-K16'). Les deux dispositifs DES effectuent leurs processus de conversion en même temps, pour éviter que la configuration de consommation de courant ne révèle les clés de chiffrement utilisées.
