IEEE 802.11的WEP算法安全性浅析

Security Analysis of WEP Algorithm Used in IEEE 802.11

本文简要介绍了IEEE 80 2 .11无线局域网的安全保证算法———WEP算法 ,指出了该算法的安全性漏洞 ,并针对这些漏洞给出了对其实施攻击的方式。随后介绍了它的改进版本TKIP算法对WEP存在问题的对策。最后提出了一些现有设备使用中提高安全性的解决措施。

The WEP security algorithm used in IEEE 802.11 wireless LAN is introduced. Under the basis of a systematical analysis, flaws embedded in WEP are pointed out, and correspondingly, several attacking methods are provided to prove the weakness of WEP. The upgraded version of WEP algorithm-TKIP was also introduced and analyzed. At last, some potential solutions to the security problems are also proposed in using existing IEEE 802.11 equipments.
