关于无线局域网的安全规范WPA的研究

Study on Wireless LAN Security Specification of WPA

无线局域网在经过一段时间的快速发展后,现在越来越多的被应用于现在的生活中,而安全问题也一直伴随着无线局域网,成为无线局域网发展的最大隐患,安全机制也随之不断的更新以保证无线局域网的通信安全,新的安全规范Wi-Fi保护接入(WPA)取代安全机制有线对等保密(WEP)成为新的安全标准。分几方面比较了WEP与WPA,对于WEP存在的问题进行了阐述,进而分析了WPA所采用的核心技术,并分别介绍了临时密钥完整性协议,信息完整性代码,及IEEE802.1X协议等WPA所应用的新技术。

With its rapid development for a period of time,WLAN is increasingly used in the actual life.However,the problem of security always accompanies WLAN and becomes the biggest hidden dangers.The security mechanism is continuously updated,thus to ensure the security of WLAN communication.WPA,instead of WEP,becomes the new security standard.This paper makes comparison of WPA and WEP,discusses the problems existed in WEP,analyzes the core technologies in WPA,and describes the protocols respectively,including TKIP,MIC,IEEE802.IX.
