A New Improved Secure Password Authentication Protocol to Resist Guessing Attack in Wireless Networks
Y. C. Lee, Yi-Pei Hsieh, Peng-Sheng You · 2008
Wireless communication is widely used today. It transmits information through an open network such that it always suffers by a variety of attacks. In 2006, Yoon et al. proposed a secure password authentication protocol for wireless networks to fix the drawback ofMa et al.' s protocol. In this article, we will show that the Yoon et al.' s protocol is vulnerable to both off-line password guessing attack and replay attack. We will present a new improved protocol to fix the flaw. As shown, the improved protocol is secure while the computation cost is quite low.
