CA 2509420
The communication terminal (2) of a communication system (1) comprises a virtual network switch (22) which can alter the destination of data being transmitted/received between the communication terminal (2) and a network (5) forcibly, wherein data is transmitted/received between the network (5) and the communication terminal (2) through a portable electronic device (3). Various functions, including a security function, can be supplemented by providing the function of software mounted on the portable electronic device (3) itself to the communication terminal (2). Even if a communication terminal connected directly with the network is not provided with such functions as VPN, firewall or virus check, high-safety communication can be ensured utilizing these security ensuring means mounted on the portable electronic device.
Le terminal de communication (2) d'un système de communication (1) comprend un commutateur de réseau virtuel (22) qui peut modifier sensiblement la destination des données transmises / reçues entre le terminal de communication (2) et un réseau (5), les données étant transmises / reçues entre le réseau (5) et le terminal de communication (2) via un dispositif électronique (3). Diverses fonctions, y compris une fonction de sécurité, peuvent être mises en oeuvre grâce à l'attribution d'une fonction logicielle installée dans le dispositif électronique (3) directement au terminal de communication (2). Même si un terminal de communication connecté directement au réseau n'est pas muni de fonctions telles que VPN, paroi coupe-feu ou antivirus, on assure une communication haute sécurité grâce à l'utilisation de ces moyens pour assurer la sécurité, installés dans le dispositif électronique portatif.
