Identity Authentication Scheme Using OTP in Wireless LAN
Xizhao Luo · Jisuanji gongcheng · 2008
This paper analyzes the identity authentication scheme using One-Time Password(OTP) for 802.11 wireless LAN, points out a design insufficiency in this scheme, and demonstrates three kinds of attack. In addition, an improved scheme without additional computational complication which can resist the man-in-middle attack, conspiracy attack and Denial-of-Service(DoS) attack is proposed. So the developed scheme is provided to avoid design insufficiency and has higher security compared with the original scheme.
