In order to strengthen preventing functions of data leakage, falsifying, camouflage, approach and attack without changing a program of a higher rank application, encryption and decryption logic arrangement is carried out on the transmission side and on the reception side and this is offered to a new encryption system TCP2 applied to a payload of a protocol which corresponds to TCP or UDP existing in a transport layer. By employing this TCP2, a cryptograph process communication can be realized by dissolving various kinds of restrictions which a conventional IPsec or SSL possesses without receiving a restriction of a higher rank application and at the same time, by obtaining compatibility in an IP layer.

Selon l'invention, pour renforcer la fonction de prévention des fuites, altérations, mystifications, intrusions ou attaques se rapportant aux données, sans modification d'un programme d'application nodale supérieure, un nouveau système de chiffrement, appelé TCP2, est mis en oeuvre dans lequel une logique de chiffrement/déchiffrement est retenue par le côté émission et le côté réception et appliquée à la charge utile du protocole correspondant au protocole TCP ou UDP présent dans la couche transport. L'utilisation de TCP2 permet d'éliminer diverses restrictions liées aux protocoles IPsec ou SSL et d'établir une communication de gestion du chiffrement compatible dans la couche IP, sans être limité par l'application nodale supérieure.
