摘要

Recently, Lee and Lee showed that Hsu et al.’s authenticated key agreement scheme is vulnerable to the modification attack and then proposed an improved scheme. In this paper, we argue that the Lee and Lee’s scheme cannot withstand the password guessing attack. Hence, we propose an improved scheme to solve this problem.
