0引言近年来,无线网络技术的快速发展使其应用门槛逐步降低,同时电子元件的更新与降价,也使得其被大众所接受。无线网络具有布线简便,接入方式灵活的优点。但是,无线网络利用无线电波在空中传送数据,其发送方式是开放的、广播式的,这就给所传送数据带来了一定安全隐患。由于每个人都可以接收无线信号,无线网络的安全可能会遭到以下几种威胁:信息泄露攻击、搜索攻击、无线身份验证欺骗攻击、拒绝服务攻击、网络接管与篡改等。因此,
0 Introduction In recent years, the rapid development of wireless network technology to gradually reduce the threshold of its application, while the electronic components of the update and price cuts, but also makes it popular with the public. Wireless networks have the advantages of easy wiring and flexible access methods. However, the wireless network uses radio waves to transmit data over the air. The sending method is open and broadcast, which brings a potential security risk to the transmitted data. As everyone can receive wireless signals, the security of the wireless network may suffer from the following threats: information leakage attacks, search attacks, wireless authentication spoofing attacks, denial of service attacks, network takeover and tampering. therefore,
