端口访问控制

本文以无线安全网关为基础，分析了当前无线局域网所面临的用户访问控制问题。根据网络端口访问控制标准IEEE802.1x的用户认证协议，提出了无线用户访问控制方案。

Based on the wireless security gateway , this paper analyzes the problems of user access control WLAN faces to at present , proposes the scheme of wireless user access control based on network port access control standard IEEE 802.1x user authentication protocol .

通过调用执行于内核态的Vxd设备驱动程序间接实现对端口的访问控制，提高端口访问的安全性。

It can indirectly access I / O ports by calling Vxd under kernel state to increase its safety .

主要分析研究了IEEE802.1x基于端口的访问控制协议、EAP可扩展认证协议、EAP／RADIUS协议和动态密钥管理协议，在此基础上提出了无线局域网的安全接入系统解决方案。
