<p>Disclosed is an authentication system, wherein, when an SSO authentication server (30) successfully authenticates a user of a user terminal (20), an SSO login web server (10) uses an authentication key to register the user's permissions information and terminal identification information that permits connection using a prescribed virtual circuit in the memory unit (18) of an SSL relay server. Consequently, a user terminal that corresponds to the terminal identification information that is stored in the memory unit (18) may be considered an authenticated user terminal. Thus, when a connection request is received from the user terminal (20) that is connected to the Internet (50), it is possible to appropriately authenticate the user terminal by determining whether the terminal identification information of the user terminal that issued the connection request is registered in the memory unit (18).</p> |
