无线局域网WLAN应用的关键在于保证数据通信的安全性,由于无线通信固有的开放性,导致无线通信存在易被窃听、截获、篡改等弱点。IEEE802.11b中定义的有线网等同安全协议WEP,但研究与应用表明其存在极大的弱点,无法真正提供健壮的安全保障。为此,Wi-Fi提出了兼容WEP改善机制WAP(
The key of wireless LAN WLAN application is to ensure the security of data communication. Due to the inherent openness of wireless communication, wireless communication is vulnerable to eavesdropping, interception and tampering. IEEE802.11b defined wired network equivalent security protocol WEP, but research and application shows that there is a great weakness, can not really provide robust security. To this end, Wi-Fi proposed WEP improvement mechanism WAP (
