An Improvement of a Simple Authenticated Key Agreement Algorithm

Eric Jui-Lin Lu and Min-Shiang Hwang

ABSTRACT

Soe and Sweeney’s Simple Authenticated Key Agreement (SAKA) algorithm, based on the Diffie-Hellman method, is a password-based key agreement algorithm which is simpler than other published methods and prevents the man-in-middle attacks. However, SAKA is vulnerable to guessing attacks if passwords are poorly chosen. In this article, we further improve the SAKA method, which is simpler than the SAKA algorithm and can defeat both the man-in-the-middle and guessing attacks.
