Link-Layer Protection in 802.11i WLANs With Dummy Authentication
The current 802.11i standard can provide data confidentiality, integrity and mutual authentication in enterprise Wireless Local Area Networks (WLANs). However, secure communication can only be provided after successful authentication and a robust security network association is established. In general, the wireless link layer is not protected by the current standard in WLANs, which leads to many possible attacks, especially in public open-access wireless networks. The authors argue that regardless of the type of network under consideration, link-layer protection and data confidentiality are of great importance in wireless applications. This paper first identifies and analyzes the security issues ignored by the current 802.11 security standard.
