PROBLEM TO BE SOLVED: To enhance the security function of a wireless communication terminal. SOLUTION: A communication terminal 40 decodes the SSID (Service Set IDentification) and a MAC (Media Access Control) address of a base station 30 included in a received beacon and authenticates the base station 30 by discriminating whether the SSID obtained by decoding the beacon is coincident with the SSID stored in an SSID storage area 408a and whether the MAC address obtained by decoding the beacon is matched with any MAC address in a base station address storage table 408b. Further, the communication terminal 40 measures a radio wave reception strength of the beacon received from each base station 30 when the communication terminal 40 is present in an area wherein a plurality of basic service areas are overlapping and authenticates the base station 30 in the order of stronger radio wave reception strength.
