Off-line Password Guessing Attack on An Efficient Key Agreement Protocol for Secure Authentication
Rongxing Lu, Zhenfu Cao · International journal of network security · 2006
In 2004, Kim, Huh, Hwang and Lee proposed an efficient key agreement protocol for secure authentication. In this paper, we shall show that their proposed protocol cannot resist the off-line password guessing attack and therefore present a modified protocol to avoid this attack.
