Deploys The Security Wireless Campus Net

With the development of wireless network technology in recent years, the wirelessnetwork is applied widely for its flexibility, removability and expansibility. Theapplication is high valuable as the supplement or substitute to the wired network. Utilizingthe wireless technology to optimize the campus net is one of its applications. But thesecurity problem of wireless local area network already became the key question. So theresearch on security of the wireless campus net, which is the obstacle of networkpopularization, has great significance to impulse the evolution of wireless network.The paper firstly introduced the development and characteristics of the wireless localarea network, and pointed out the importance of the security of the wireless campus net.Secondly, safety mechanism of the wireless local area network is deeply analyzed. Thethesis construed the possible attack mean and limitation, existed in the wireless local areanetwork. Then the article provided the solution to the security problem based on the IPSecVPN, which settle the issue of the multi-area campus network. And 802.1X standard andthe Radius basic principle are presented. Finally, according to the demand of WuxiCommerce Institute, the paper proposed a wireless campus net safe solution, integratedwith VPN and 802.1 X technologies, to ravel out the problem of safety identification. Theresearch established the foundation of further study and application of wireless network.
