Research with OPNET: Security overhead in wireless LANs

After initial negligence on security in IEEE 802.11-based wireless LANs (WLANs), Wi-Fi and IEEE have worked diligently to bring strong protection in the form of Wi-Fi protected access (WPA) and now IEEE 802.11i. The later, that is IEEE 802.11i, provides strong protection, but its effect on lowering through and increased delay is unknown. In this paper, we will present the results of initial studies on parts of this architecture. Our focus will be on authentication using IEEE 802.1X and key management using temporal key integrity protocol (TKIP). We will study delays and throughput overhead.
