A system for setting security in a wireless network system using a cluster function. An access point stores a list of candidate terminals of each neighboring access point. When an arbitrary terminal sends an access request, the access point determines whether or not the terminal is authenticated using the stored list of candidate terminals, and transmits an authentication success message to the requesting terminal if the requesting terminal is authenticated. The terminal performs hand-over to the access point without performing authentication upon receiving the authentication success message from the access point in response to the access request. Thus, the hand-over time of a Wi-Fi phone is reduced in an environment based on Wi-Fi Protected Access (WPA) that is one of the strongest wireless LAN security policies, so that the safety and mobility of wireless LAN services can be improved at the same time. |
