如何保证无线局域网的安全性是使无线局域网更好的为人们服务的首要问题,本文针对现有无线局域网的主要几种安全技术进行了分析,提出了安全技术的原理、优点和不足之处。综述了当今无线局域网的安全隐患,和针对这类安全隐患的解决办法。并根据OSI的层次对无线局域网的安全性进行了分层讨论,总结了如何在现有安全技术的基础上更好的保障无线局域网安全。本文主要包括以下几个方面的工作:
一、本文介绍了无线局域网的组成、原理、无线局域网的类型以及运作方式。
二、介绍了无线局域网主流的几种安全机制,有线等效加密(WEP)、端口访问控制技术(IEEE802.1x)、WPA (Wi-Fi Protected Access)。包括它们的技术原理、所能解决的问题以及不足之处。并简单介绍了两种重要的加密协议TKIP与CCMP。
三、本文根据OSI的层次结构对无线局域网的安全性进行了逐层的分析,其中包括每层的安全机制和安全漏洞,以及针对这些漏洞的攻击手段。最后提出了相应的解决办法。
四、总结了采用什么方法保障无线局域网的安全。其中包括逻辑上的架构,以及安全性的架构。针对不同规模、不同安全性要求的无线局域网,采用不同的机制保障无线网络安全。

People have never stopped to facilitate the pursuit of life, and to meet the various needs of this technology is also constantly promote the development of the. In the past few years, gradually moving the whole of the world. Traditional wired networks have been unable to meet the requirements of the new way of life, therefore, wireless networks have emerged. Wireless LAN is easy to install, the use of flexible, economical, easy to expand, and other cable networks can not match the advantages of wireless LAN are therefore more widely used. However, due to open wireless LAN access features, making the attacker can easily carry out the wiretapping, edit and transmit malicious, security hinders the development of wireless LAN the most important factor.
How to guarantee the security of wireless LAN is to make a better wireless LAN service for people the most important issue, the paper against the major existing wireless LAN technologies for the security of several of the security t
