基于802.1x协议的认证系统的研究与改进

在以太网接入控制技术中，基于IEEE802.1x协议的认证系统有较大的优势，但在网络接入管理的实际中存在缺陷与不足。该文对基于802.1x协议的认证管理系统进行研究，介绍802.1x协议的体系结构，分析802.1X协同RADIUS协议应用于认证计费系统的工作原理、认证机制与流程，针对存在的问题给出一个改进的方案，通过增加网络流量作为新的认证元素，达到主动认证、高效控制的效果。

Research and Amelioration of Authentication System Based on 802.1x Protocol

The authentication system based on IEEE802.1x protocol has more advantages in LAN access, but it still has some problems and flaws based on the practice of network management. This paper gives a brief introduction to authentication architecture of the 802.1x protocol, the whole work theory, authentication mechanism and process of the system based on 802.1x and RADIUS protocol is discussed. An amelioration of the authentication system is presented. As a new element, the network flux is added to participate in its authentication. The project has advantages of automatic authentication and high efficiency in control.
