| 摘 要： | 无线局域网的802.11标准采用WEP(有线等价保密协议),用来保护链路层的通信不被窃听和其他攻击。该文首先分析了WEP协议中使用的RC4加密算法,然后给出该算法里在密钥时序安排里的两种安全漏洞,这些安全漏洞导致了针对无线局域网的可行的攻击手段存在。最后根据RC4加密算法存在的相关密钥漏洞对无线局域网进行攻击并成功获取密钥,并给出一些改进攻击手段的设想。

| Abstract: | The802.11standard for wireless networks includes a Wired Equivalent Privacy(WEP)protocol,used to protect link-layer communications from eavesdropping and other attacks.In this paper,we present analysis of the RC4encryption algorithm which is used in widely deployed WEP.And give two weaknesses in the key scheduling algorithm of RC4.The flaws lead to a number of practical attacks.Finally we make a practical related-key attack experiment based on known IV weakness and crack the key successfully.Some improvements for our WLAN attack are also available. |
