Extensible authentication protocol (EAP) and IEEE 802.1x: tutorial and empirical experience

This article presents the technical details of the Extensible Authentication Protocol (EAP) and IEEE 802.1x by using WIRE1x, an open-source implementation of IEEE 802.1x client (supplicant) and various EAP-based authentication mechanisms. By using a real implementation, 802.1x and EAP should be easily understood.
