Abstract (in Japanese) (See Japanese page) 
(in English) In 2008, Nakano et al. proposed a password authentication method, which is secure against the stolen-verifier attack. However, Nakano et al. method is a problem in safety because it input the fixed password each time in the authentication session. In this paper, we propose a secure password authentication method against stolen-verifier attack and all other already-known attacks. The proposal method is secure because it generates the authentication information by using not the fixed password but the updated private key each session.
Keyword (in Japanese) (See Japanese page) 
(in English) authentication / one-time password / stolen-verifier attack / / / / /
