| Outline of Final Research Achievements |
Among service systems running in a network, many ones adopt authentication with passwords determined by the users. Even to enable OTP authentication to enhance security, it is quite hard to modify and reset the system keeping running. Thereby we suppose to extend existing password authentication systems to OTP authentication systems by adding a center which does possession (WYH) authentication.
First, we have shown how to enhance password authentication, in which the center switches the authentication on and then usual password authentication is possible when a user tries to log-in. After that, we have shown how to construct OTP two-factor authentication with keeping modification to the original password authentication system to a minimum.
