Implement And Research Campus Network Authentication Based On IEEE802.1x

With the development of compus network, how, to carry out effective, moderate cost, and Security authentication is becoming the bottleneck of network construction. Tradetion authentication methods such as PPPOE WEB+DHCP cannot meet the need of users and ISP because of their expensive and complexity. Theirfore, authentication by way of IEEE 802.1x became a hotspot for its simple, effective Port based network access control makes use of the physical access characteristics of IEEE802.1x LAN infrastructures in order to provide a means of authenticating and authorizing devices attached to a LAN port that has point-to-point connection characteristics, and of preventing access to that port in cases where the authentication and authorization process fails!...
