1、精选优质文档-倾情为你奉上系统中常见的攻击与防范技术分析学号:018 学生姓名: 刘洋溯摘要 有线网络自诞生以来就不断接受安全专家与黑客的考验,有线网络的安全机制日趋完善。但是无线网络出现以后,因为其传输介质的开放性,使得其更容易收到黑客的攻击,安全性能较之无线网络有较大的差距。为了改善无线局域网的安全性能,IEEE制定了802.11i标准,该标准改进了WEP加密的安全机制,在认证和秘钥管理方面做出了改进,并引入了CCMP、四次握手秘钥协商等机制。本文主要总结分析对于802.11网络的常见攻击方式和基于802.11i基础上对其中一些攻击方式的防范。关键词 无线局域网 802.11 WEPABS
2、TRACT Since the beginning of the cable network, it has to accept the test of security experts and hackers. cable network has security mechanism improvement. But with the emergency of the wireless network and its the openness of the transmission medium, it can be easier to receive the hackers attack,
3、 there is a difference compared with the wireless network security performance. In order to improve the safety performance of the wireless local area network (wlan), IEEE setting the 802.11i standard to improve the security of WEP encryption mechanism. the standard has made the improvement in the ce
