Title (EN) METHODS, SOFTWARE, AND APPARATUS FOR SECURE COMMUNICATION OVER A COMPUTER NETWORK
(FR) PROCEDES, LOGICIEL ET APPAREIL DE COMMUNICATION SECURISEE SUR UN RESEAU INFORMATIQUE
Abstract:
(EN) A method for performing secure communication between a first user's computer and second remote computer over a computer network is described. According to one embodiment of this aspect, the data space of the first computer is partition into a first secure portion (204) and a second network interface portion (206). Communication is established between the first and a second computer, and redirection (214) and filter (216) mechanisms are initialized. An instruction is received by the first computer, analyzed by the redirection mechanism (214), and passed to the filter (216) if the instruction is a protected instruction. The protected instruction is verified by the filter (216) and processed if the verification is successful.
(FR) L'invention concerne un procédé de communication sécurisée entre un premier ordinateur utilisateur et un second ordinateur utilisateur via un réseau informatique. Selon un mode d'exécution, l'espace données du premier ordinateur est réparti en une première partie sécurisée (204) et une seconde partie interface réseau (206). Une fois que la liaison est établie entre les deux ordinateurs, on redirige (214) et filtre (216) les mécanismes. Le premier ordinateur reçoit une instruction qui est analysée par le mécanisme de redirection (214) et filtrée (216) si elle est protégée. L'instruction protégée est vérifiée par le filtre (216) et traitée si la vérification aboutit.
