| Abstract: | IEEE 802.11 supports 802.1x to provide strong authentication mechanism for Wireless networks. 802.1x utilizes Extensible Authentication Protocol (EAP) as a framework for authentication, allowing for a number of authentication methods to be used. Unfortunately, 802.1x includes some unprotected EAP packets during authentication process which can be easily exploited by an attacker to start different types of denial of service (DoS) attacks over wireless networks. In this paper we developed an experimental framework to demonstrate and quantify possible flooding attacks using unprotected EAP frames against wireless communications. First we setup a testbed wireless network in order to demonstrate how EAP flooding attacks take very little effort to bring a protected wireless network to a complete halt. Then via measurements and analyses we evaluate the impact and consequence of these attacks against performance of wireless network in terms of network drop rate and throughput. Results show that such attacks can easily launch, and cause serious service disruption to compromise network availability.
