随着无线网络的普及和应用,人们对无线网络的依赖程度越来越高。与此同时无线网络的安全性成为人们关注的焦点。由于无线网络传输媒体的开放性、无线终端的移动性和网络拓扑结构的动态性,以及无线终端计算能力和存储能力的局限性,使得有线网络环境下的许多安全方案和技术不能直接应用于无线网络,同时也给安全方案的实施增加许多限制。时下好多个人都用起无线路由器,默认状态下无线路由是用WEP加密的,但稍有常识的人都会知道WEP非常的不安全。针对现有无线加密算法的各种弊端,分析各种无线密码破解的手段和无线攻击手段,结合多方面的防护策略,构建一个适合各种场所的安全无线网络方案。
With the popularization and application of wireless networks, people rely more and more on wireless networks. At the same time, wireless network security has become the focus of attention. Due to the openness of the wireless network transmission media, the mobility of the wireless terminal and the dynamic of the network topology, as well as the limitation of the computing capability and the storage capability of the wireless terminal, many security solutions and technologies in the wired network environment can not be directly applied to the wireless Network, but also adds many restrictions to the implementation of security programs. Nowadays, many individuals use wireless routers. By default, wireless routes are encrypted with WEP, but a little common sense people know that WEP is very insecure. Aiming at various drawbacks of existing wireless encryption algorithms, various means of wireless password cracking and wireless attacking methods are analyzed, and a multi-layer protection strategy is combined to build a secure wireless network solution suitable for various places.
