摘　　要：提出了一种基于地址解析协议(ARP)的局域网访问控制方案。通过实时捕获、分析了网络数据报发现登录局域网络的非法主机,采用ARP协议机制杜绝其对局域网内合法主机的非法访问;利用服务器对网络主机IP地址、MAC地址和其他辅助信息的多重认证,以及网络主机客户端ARP缓存机制实现网内合法主机之间的限制访问,从而有效地保护局域网资源。The access control of local area network is a common security problem which involved the resource protection of local area network. In this paper, a project of access control of local area network based on ARP protocol is presented. It can be used to detect and refuse the illegal computers that try to log on and access the local area network by capturing and analyzing the network packets. On the other hand, through the authentication of the local area network server and based on the ARP buffer principle, it can be also used to control the access between the legal computers of the local area network. So that it is an effective way to protect the resource of local area network. The project is convenient and useful.
