论WLAN的安全标准及安全机制

无线局域网WLAN是现有的有线局域网的扩展,它使用无线电波来承载数据。利用WLAN进行通讯必须具有较高的通讯保密能力。本文分析了WLAN目前存在的主要安全问题,并根据WLAN的发展动态分别介绍了WLAN网络产品现行采用的IEEE802.11b标准、思科的LEAP协议和PEAP协议的安全技术原理及存在的主要问题,论述了我国提出WAPI新安全机制的工作原理及特点,指出随着技术及应用的发展和进步,WLAN的通讯安全能力会越来越强,而WAPI完全遵循国际标准化,体现了我国标准制定工作的公信力。

Safety Standard and Safety Mechanism of WLAN

WLAN is the expansion of existing wired local area network.It uses radio wave to bear the data.Higher communication security ability must be needed when using WLAN to implement communication.In this article we analyzed the main security issue that WLAN exists at present;introduced the safe technology principle and the major problem that exists in safety standard agreements such as IEEE802.11b's international standard that WLAN network production adopts at present,LEAP and PEAP protocol of Cisco,according to the development trend of WLAN.We also discussed the work theories and characteristics of the new WAPI security system,and pointed out that the communication security ability of WLAN will become more and more strong with the development and progress of the technology and the application.At the same time,because it follows the international standard,WAPI reflects the confidence of the standard establishment in our country.
