基于802.1X协议的局域网安全接入认证的设计与实现

Design and Implementation of Secure Access Authentication for Local Area Network Based on 802.1X Protocol

随着计算机网络的快速发展,网络安全成为个人、企业乃至国家关注的重点。802.1X协议作为局域网端口的接入控制机制在以太网中被广泛应用,主要解决了网内认证和安全方面的问题。基于此,笔者从802.1X协议原理、快速部署、冗余备份和逃生几个方面,分析了基于802.1X协议在局域网接入认证的设计与实现,探索出了一套针对企业局域网用户接入安全的解决方案。

With the rapid development of computer networks,network security has become the focus of attention of individuals,enterprises and countries.The 802.1X protocol,as an access control mechanism for LAN ports,is widely used in Ethernet,mainly solving the authentication and security problems in Ethernet.Based on this,the author analyzes the design and implementation of 802.1X protocol-based LAN access authentication from the aspects of 802.1X protocol principles,rapid deployment,redundant backup,and escape,and explores a set of solutions for enterprise LAN user access security.
