| 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!... |
