Abstract

L'invention concerne les télécommunications et plus particulièrement des procédés et dispositifs cryptographiques destinés à la protection des informations transmises via des réseaux de télécommunications. L'invention permet d'augmenter la résistance à la crypto-analyse différentielle et la vitesse de chiffrage. Selon l'invention, un bloc de données numériques (BDN) est divisé en N ≥ 2 sous-blocs de données numériques (SBDN) et on effectue dans chaque sous-bloc un replacement opérationnel dirigé, réalisé par S cycles effectués en séquence. Chaque cycle comprend la réalisation de Z replacements opérationnels dirigés et une permutation opérationnelle fixe. Le replacement opérationnel dirigé se fait a moyen d'un vecteur de direction préalablement formé au moyen d'un SBDN ou d'un SBDN et d'une clé secrète. On cite des exemples de réalisation du procédé fixant une transformation cryptographique à sens unique et de chiffrage.
