无线局域网的安全技术分析及比较

Analysis and comparison of WLAN security technology

随着无线局域网的应用领域不断拓宽,无线局域网的安全越来越受到重视,无线局域网的安全技术也随之得到了迅速应用和发展,为了选择合适的无线局域网安全技术,根据在无线局域网网络产品中广泛应用的IEEE802.llb标准下提供的安全服务,从无线局域网的数据加密和安全认证两大主要安全方面出发,对目前广泛应用的安全技术进行了简要介绍,并分析了各个安全技术的优势和缺陷,最后对无线局域网的安全技术进行了综合比较,并做出结论如何选择合适的无线局域网安全技术,对于无线局域网安全技术的发展具有一定的积极意义。

With the constant increasing of WLAN application field,security of WLAN is more and more emphasized, and the security technology of WLAN gets applied and developed as well. In order to choose the proper WLAN security technology,this paper bases on the WLAN security service provided by IEEE802.11b standard which is applied widely in WLAN network product ,from aspects of data encryption and security certification which are major WLAN security services, briefly introduced the major security technology at present, analyzed the advantages and disadvantages of the security technology,and drew a synthetical comparison between WLAN security technology. Finally the conclusion how to choose the proper WLAN security technology was given. It makes sense for the development of WLAN security technology.
