Security has always been a major concern in the development of Wireless Local Area Networks (WLAN) as they are based on wireless technology, i.e. no physical connections exist. One of the major problems in WLAN security is authentication.
EAP (Extensible Authentication Protocol) is an authentication framework that uses several authentication techniques such as TLS, TTLS, PEAP and LEAP. EAP-TLS (EAP- Transport Layer Security Protocol) is widely used in WLAN (Wi- Fi /802.11 and Wi-MAX/802.16) as a solution to the authentication problem. This paper presents EAP-TLS security in details, explores its weaknesses and provides detailed EAP-TLS assessment. As a solution to the presented flaws, we present in details the proposed Moderate EAP- TLS for overcoming such shortages. Finally, we present a security assessment to our proposed protocol compared to EAP-TLS.
