<p><P>PROBLEM TO BE SOLVED: To provide an authentication system capable of also coping with terminal authentication of a radio LAN without depending on a sort of a tunneling communication system, having high user's operability and capable of improving security strength. <P>SOLUTION: The authentication system includes: a call control means; an authentication permission information provision means for call-connecting with a telephone terminal operated by a registered user by call control of the call control means, receiving a request from the telephone terminal, generating authentication permission information necessary for the authentication of an access destination, and providing the generated authentication permission information to the telephone terminal and an access control means; the access control means for determining whether authentication permission information acquired from a user terminal requesting connection to the access destination coincides with the generated authentication permission information or not; and an authentication means for authenticating the access destination by the user terminal. The telephone terminal inputs the authentication permission information to the user terminal as sound information, and the user terminal provides the authentication permission information input from the telephone terminal as the sound information to the access control means. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
