【摘要】 随着计算机技术的快速发展，网络应用已经在全球得以推广。无线局域网结合了无线通信技术和计算机网络的优势，实现在短距离内的无线网络通信。因为其无线的特点，网络的安全就成为一个非常重要的课题。 本文的研究主要针对无线局域网的接入认证过程，分析传统的无线局域网的安全处理方法存在的缺点和不足。然后在分析802.1x协议的基础上采用EAP-MD5协议作为其认证框架，构建无线接入控制点。在该无线接入控制点实现一种基于802.1x协议的EAP-MD5认证方式，通过IP地址绑定MAC地址的方式作为认证系统对端口控制的实现。在实现该认证方式的基础上，增加认证系统对认证服务器的身份验证提高整个认证流程的安全性。最终给出了一种无线局域网接入认证的实现。 无线局域网处于飞速发展的阶段，各种协议和标准都在不断完善中，对无线局域网的安全问题的探讨将会一直持续下去。更多还原

【Abstract】 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.更多还原
