Title (EN) SECURE COMMUNICATION SYSTEMS
(FR) SYSTÈMES DE COMMUNICATION SÉCURISÉS
Abstract:
(EN) A communication system includes a device that is capable of sending and receiving messages and is provided with a unit of Application Software that contains an encryption algorithm. The preferred types of algorithm are a rotary cipher algorithm and a stream cipher algorithm each capable of generating a crypt image using ASCII characters, and a stream cipher algorithm capable of generating a crypt image using printable characters.
(FR) Un système de communication comprend un dispositif qui est capable d'envoyer et de recevoir des messages et qui est pourvu d'une unité de logiciel d'application qui contient un algorithme de chiffrement. Les types d'algorithme préférés sont un algorithme de chiffrement rotatif et un algorithme de chiffrement de flux qui sont chacun aptes à générer une image chiffrée à l'aide de caractères ASCII, et un algorithme de chiffrement de flux apte à générer une image chiffrée à l'aide de caractères imprimables.
