Access point device and method for supporting multiple authentication policies

An AP(Access Point) device and a method for supporting multiple authentication polices is provided to prevent a network element from being overlapped by supporting an authentication service for a plurality of terminals using various authentication policies through one connection node. An AP device for supporting multiple authentication polices includes a high frequency process unit(410), an authentication policy selection device(450), an authentication unit(470), and an authentication server selection unit(490). The high frequency process unit(410) processes the high frequency signal transmitted and received through an antenna. The authentication policy selection device(450) selects a corresponding authentication module(470) according to authentication method information outputted from an authentication method mapping unit(430). The authentication unit(470) includes a plurality of authentication modules. The authentication server selection unit(490) performs an authentication process through the authentication server selected by using a signal outputted through the selected authentication module.
