Implementation of Extensible Authentication Protocol in OPNET Modeller

As wireless technology is becoming more and more prevalent; security in such networks is becoming a challenging issue and is in great demand. One of the most powerful tools in this area which helps to simulate and evaluate the behaviour of networks and protocols is OPtimised Network Engineering Tool (OPNET). Although OPNET has covered a wide range of models and a variety of protocols, there is no implementation of security in it. In this paper we implement and simulate Extensible Authentication Protocol (EAP) using discrete event simulator OPNET modeller. EAP is an authentication framework which is compatible with IEEE 802.1x the security framework for IEEE 802 family. Keywords-WLAN; Security; Authentication; EAP; OPNET;
