The Research And Application Of Access Authentication Based On 802.1x In WLAN

With the rapid development of computer technology, network application is being widely applied to daily life. The Wireless LAN takes the advantage of both wireless communication technology and wired network, and realized the wireless communication with network in a short distance. Because of its wireless characteristic, the security of the network is very important.This paper focuses on the access authentication period of WLAN, and analyzes the disadvantages and advantages of traditional ways. After that, the 802. 1x protocol is analyzed and then it uses the EAP-MD5 protocol as the authentication framework. A wireless access control server is constructed. It realizes the EAP-MD5 authentication way based on the 802.Ix protocol, it uses the way of ip address binding mac address to realize the way of controlling the ports. And it increases the security by the identification of the Authencticator and the authenticatation server. After this, puts forward a method to implement it.WLAN is in the period of rapidly increase, many standards and protocols are being improved to enhance securities. The discussion of the security on WLAN will be on.
