Research And Design About Security Architecture Of Wireless Campus Network

As an important infrastructure construction of college education informatization, the development of wireless network in campus of China has passed through more than ten years. Compared with the traditional wired network of campus, the terminal wireless campus network is advanced in using wireless transmission mode for accessing, no matter whenever or wherever, it can allow people to be flexible and convenient to access to cyber source, and will no longer be subject to geographical constraints. On the one hand, with the rate of wireless rapidly increased, more and more people expect wireless can replace the original cable. But on the other hand, due to the use of the wireless transmission, the security of user access becomes worse, more vulnerable to attack or destroy. So we need a wireless campus network to solve this security problem.At present, the wireless campus network is rapidly developed toward high-speed, large-scale and centralized management. In order to meet the need of such large-scale centralized management, network architecture decentralized from the early "fat" AP structure to the development of current centralized "thin" AP+AC structure. Along with the change of network architecture, security architecture for wireless network changes, centralized security management from decentralized safety management development to development, from safety management to safety management of wireless access network and wired access converged, security solutions are increasingly being proposed, how to choose a security architecture to meet the wireless the campus network security needs to be a process of wireless campus network design and construction of content must be considered. Wireless campus network architecture, the main work of this paper is through the study of different, the wireless LAN security technology mature, comprehensive design a universal wireless campus network security architecture.This paper firstly introduces the idea and method to design a security architecture of wireless and the main technologies about network security, begin with the study of different wireless campus network construction, it gives security scheme suitable for different network architecture through the analysis of the characteristics of different network architecture. Design and network security function testing scheme was given a suitable for medium scale universities complete wireless campus network security architecture, to comprehensively discusses how to design the whole process of building a wireless campus network security architecture. The design scheme can meet the security needs of the construction of university campus wireless network, provides the design reference complete network engineering practice.
