Abstract: This paper proposes the wireless Man In Middle(MIM) framework, which actively proves the vulnerability of MIM by applying the MIM technique in WLAN environment, whose security is applied with 802.1X and Extensible Authentication Protocol(EAP). It describes the design of the required functions and modules, proposes that it is possible to collect WLAN authentication information of the unauthorized user by using the wireless MIM framework under the EAP-MD5 and EAP-TTLS environment.

Key words: 802.1X protocol, Extensible Authentication Protocol(EAP), Rouge AP, Man In Middle(MIM) attack
