If the input performance of a password is requested from a user terminal(100), an authentication server(200) produces the new correspondence value set corresponding to unit values comprising password. An authentication server produces the matched value set corresponding to unit values comprising password. Business information for authenticating to the encrypted correspondence value and password is transmitted from the user terminal to the certificate server. The certificate server decodes the encrypted correspondence value. The authentication server performs the task according to the business information.
