Authentication Mechanism Using One-Time Password for 802.11 Wireless LAN

Wireless local area networks (WLANs) are quickly becoming ubiquitous in our every day life. The increasing demand for ubiquitous services imposes more security threats to communications due to open mediums in wireless networks. The further widespread deployment of WLANs, however, depends on whether secure networking can be achieved. We propose a simple scheme for implementing authentication based on the One-Time Password (OTP) mechanism. The authentication protocol is proposed to solve the weak authentication and security flaw problem of the WEP in 802.11 WLAN. Further we have simulated the implementation of proposed scheme and EAP-OTP and analyzed the performance in terms of different performance metrics such as response time and authentication delay.
