Abstract:

The theory and authentication process of IEEE 802.1X protocol was analyzed and introduced. According to the requirements of authentication and port control of switch in Ethernet application environment, to solve the questions of port control, selection of authentication scheme, compatibility and security of authentication server, an extended scheme of 802.1X was given. It was implemented on a 100M switch, and tested in Ethernet environment.

Key words: 802.1X protocol, switch, Ethernet, security, authentication

摘要：

对IEEE802.1X协议的原理和认证流程进行了分析和介绍。根据交换机在以太网应用环境中对认证和端口控制的实际需求，结合端口控制和认证机制的选择，以及认证服务器的兼容性和安全性等问题，提出了一种802.1X协议的扩展方案。该方案在百兆交换机上予以实现，并在以太网环境中进行了认证测试。
