Wep协议抗线性攻击缺陷分析及改进

Analysis of the Flaw Against Line Attack and Improvement of Wep Protocol

分析了目前WEP协议的主要加密算法中存在的几个主要问题:WEP加密机制、IV的重复使用、对ICV(in-tegrity check value)的攻击、对RC4算法的攻击。对这些问题产生的原因进行了比较详细的说明并给出了一个简单改进方案。

For lack of taking the security problems into consideration at the time when WEP is designed, some security flaws are left behind in WEP. In the paper, the analysis of security characters and security requirement of CR4. are given.
