Abstract

Système de communication cryptographique pour la communication entre un noeud A et un noeud B via une passerelle de cryptage de communication sûre. Un noeud A compose un fichier à transférer au noeud B (50). Le fichier est crypté (53) au noeud A, à l'aide de l'algorithme et de la clé du noeud A. Le fichier crypté est envoyé à la passerelle de cryptage (54). A la passerelle de cryptage, l'expéditeur, le noeud A, est identifié (56) et le destinataire prévu, le noeud B, est identifié (58). Le fichier crypté est décrypté à l'aide de l'algorithme et de la clé (66) du noeud A et le fichier décrypté est recrypté à l'aide de l'algorithme et de la clé (68) du noeud B. La passerelle de cryptage envoie ensuite le fichier recrypté au noeud B. Le noeud B utilise son algorithme et sa clé de décryptage pour décrypter le fichier (74).
