Abstract

Recently, Ku and Wang showed that Tseng’s modified authenticated key agreement protocol is vulnerable to two attacks and proposed an improvement to withstand these attacks. However, this letter will show that this improvement is still vulnerable to the modification attack, which is contrary to their claims. Additionally, we proposed an improvement to eliminate this security flaw.
