摘要
近年来,无线局域网技术和市场都有了突飞猛进的发展。而随着IEEE802.11无线局域网的普及,网络的安全性问题也正在变得日益严峻。WEP协议是IEEE802.11标准规定的数据加密机制。WEP虽然提供了64位和128位长度的密钥机制,但是它仍然存在许多缺陷。文中详细分析了WEP加密和解密的原理,从3个方面说明了WEP存在的安全隐患,并依次讨论了各安全隐患所对应的解决方案。
Recendy, the technology and market of wireless local area network have gained great development. With the popularization of IEEE 802.11 wireless local area network, the network security has become more and more important. WEP algorithm is the data encryption technology prescribed by IEEE802.11. Although WEP provides 64bit and 128bit key mechanism, it still has many limitations. This paper analyzes the encryption principle, deeryption principle of WEP, and narrates the secure hidden troubles of it from three aspects, then discusses the troubles＇ corresponding projects.
