摘要
Password authentication is a type of authentication protocol for communications over an insecure network. Recently, Kim, Jeon, and Yoo gave an improvement of Yang-Shieh password authentication schemes to resist an existing forgery attack. However, in this paper, we construct a new forgery attack and show that Kim-Jeon-Yoo schemes are not secure under our attack.
