Security analysis of the generalized key agreement and password authentication protocol
Her‐Tyan Yeh, Hung–Min Sun, Tzonelih Hwang · IEEE Communications Letters · 2001
We show that the enhanced version of the generalized key agreement and password authentication protocol, proposed by Kwon and Song (see IEICE Trans. Commun., vol.E83-B, no.9, p.2044-50, Sept. 2000), is insecure against off-line password guessing attacks.
