An Approach for Prevention of MitM Attack Based on Rogue AP in Wireless Network

Abstract

With the rapid development of WLAN, more and more schools and businesses have begun to provide the WLAN for users. However, WLAN is considerably more susceptible to MitM (man- in-the-middle) attack. To overcome it, we propose a dynamic password technology named Two-way Dynamic Authentication Technology (TDAT). It uses two-factor during the initial authentication, and uses a two-way hash chain during the cross-domain authentication. TDAT effectively protects users' authentication credentials and improves users' experience. In an actual wireless network environment, we implement a MitM attack framework based on Rogue AP. Then we effectively prevent this MitM attack by using TDAT. Moreover we analyze the security of TDAT by using BAN logic.
