In this paper, the author supplies an overview of wireless network protocols, and then, introduces several main wireless safety techniques, for the weakness of RCA algorithm, advances a better solution-using the latest AES algorithm to re- place RC4.

• 本文首先对无线局域网进行了概述,然后介绍了目前无线局域网中几种主要的安全技术,最后重点针对WEP(有线对等保密)技术中采用的RC4算法存在的问题,提出了用AES(高级加密标准)替代RC4算法的解决方案。
