IEEE802.1x of protocol analysis and improvement

Wireless local area network (WLAN) is more and more received people's favor by some superiority, for example, fast deployment, speed higher and so on. With the development of wireless WLAN, its network security issues become more attention. Security problem is still insufficient in the current IEEE802.1x series of standard; it has become an important research topic that how to ensure the security of WLAN. This paper proposes the improved program of protocol for IEEE802.1x protocol's flaw that it suffers the denial of server (DOS) attack and Man-in-the-Middle (MITM) Attack.
