无线网络信息安全与对策

随着技术的迅猛发展,尤其是在Intel的迅驰发布以后,其强大的市场推动力导致无线网络技术的发展越来越快。然而,由于种种原因,无线网络信息存在着泄露的危险。本文从无线网络的扩频技术、用户验证、数据加密以及WEP加密配置等主要信息安全技术分析着手,剖析出无线网络中的安全漏洞:易被发现和入侵,网络未设置WEP或WEP设计存在缺陷,802.11无线局域网对数据帧不进行认证操作等;并从合理布局、采用先进加密技术、加强安全管理等方面提出了改进措施。

Information Safety and Countermeasure of Wireless Network

With the fast development of technical,the strong market motivation of Intel′s Centrino causes wireless network technique develop more and more fast.But as for some reason,the wireless network exists the danger to reveal information.In this paper,the technology of expand frequency,consumer verification,data encryption and allocation of WEP encrypt etc are analysed.The safe leak of wireless network: easy to be found and invaded,the network has not interposed WEP,defect of WEP designing existence,the wireless local area network 802.11 does not carry out attestation operation on data frame etc.The author has brought forward improvement measure and countermeasure from some fields such as rational layout,adopting the encrypted advanced technology,reinforce safety administration.
