基于802.1x协议的用户认证研究

校园网大量用户的接入带来了对接入用户的认证问题.IEEE 802.1x协议是一种基于端口的网络接入控制协议,能够对所接入的设备进行认证和控制.锐捷SAM系统运用基于802.1x协议,采用“入网即认证”的用户管理模式,实行用户访问任何资源（包括校园网资源）之前都需要认证的用户身份认证机制,从而确保满足对信息安全管理的需要,成功地实现了建造安全可靠的校园网的目的.

Research of supplicant authentication based on 802.1x protocol

With the development of the campus network, its security becomes important. A large number of users access has brought the problem of user＇s authentication. IEEE 802.1x protocol is a kind of network access control protocol which is based on port. It is able to authenticate and control the access devices. RJ- Sam system is based on 802.1x protocol, and uses a ＂network authentication＂ user management mode. Any user is required to certificate before accessing any resources （including campus network resources）. Therefore the information security are ensured. The goal of constructing a safe and reliable network environment is successively achieved.
