A Wireless Local Area Network (WLAN) is a flexible data communication system implemented as an extension to or as an alternative for a wired Local Area Network (LAN). However, anyone can eavesdrop on information so that WLAN has the hidden security trouble such as leaking of electromagnetic wave or eavesdropping of data because WLAN adopts common electromagnetic wave as media to transmit data. Therefore, the security of WLAN is very important and outstanding. In IEEE 802.11, there are three security technologies used to ensure the data security in WLAN-SSID (Service Set IDentifier), MAC (Media Access Control) and WEP (Wired Equivalent Privacy).
