With the rapid development of wireless mobile communication, an authenticated key agreement protocol for mobile devices is an important issue in secure communication. Due to limitations in power consumption, bandwidth and computation, an efficient authenticated key agreement protocol can be used in the wireless mobile networks. In 2005, Sui et al. proposed an Elliptic Curve based Password Authenticated Key Agreement (EC-PAKA) protocol. Elliptic curve cryptography, is more efficient in terms of computation than other authentication key agreement protocols. But, Sui et al.'s EC-PAKA protocol cannot resist the off-line password guessing attack.
