<p>PROBLEM TO BE SOLVED: To prevent illegal access (non-permitted invasion) from being performed by anybody by destroying a certification mechanism based on a user ID and password of a remote access server. SOLUTION: A user ID and a password are sent from a remote access terminal 5, and after the access enable certification is provided, a remote access server 1 which receives these data sends an IP address to inhibit access to a network as an IP address to be used, or sends the proper IP address through code conversion, while the remote access terminal 5, which receives this address, uses the IP address to enable access to a computer network set to the present terminal while ignoring the IP address, or performs access by decoding the received IP address to the proper IP address through code conversion.</p> |
