Abstract

L'invention concerne des systèmes et des procédés qui utilisent un protocole de sécurité récursif destiné à la protection de données numériques. Ces systèmes et ces procédés peuvent inclure le chiffrement d'un flux de bits avec un premier algorithme de chiffrement et l'association d'un premier algorithme de déchiffrement du flux de bits chiffré. Le flux de bits résultant peut ensuite être chiffré avec un deuxième algorithme de chiffrement afin d'obtenir un deuxième flux de bits. Ce deuxième flux de bits est alors associé à un deuxième algorithme de déchiffrement. Ce deuxième flux de bits peut ensuite être déchiffré par un destinataire utilisant des clés associées.
