To provide an unauthorized communication prevention system and an unauthorized communication prevention method that can improve security against unauthorized communication that uses a repeater.SOLUTION: An unauthorized communication prevention system 19 is used for an authentication function (authentication system 5) for authenticating a terminal 1 by short-range wireless communication between a communication device 9 provided in an operated body 2 of the terminal 1 and the terminal 1. The unauthorized communication prevention system 19 is a system using a satellite radio wave Sa transmitted from a communication satellite 21. A comparison unit 27 compares first position information Da1 acquired by the terminal 1 with second position information Da2 acquired by the operated body 2 when the communication between the terminal 1 and the communication device 9 is established. A determination unit 28 determines whether to allow continuation of the established communication on the basis of a comparison result of the comparison unit 27.SELECTED DRAWING: Figure 1
【課題】中継器を用いた不正通信に対するセキュリティ性を向上できる不正通信防止システム及び不正通信防止方法。【解決手段】不正通信防止システム19は、端末1の被操作体2に設けられた通信機9と端末1との間の近距離無線通信によって端末1を認証する認証機能(認証システム5)に使用される。不正通信防止システム19は、通信衛星21から送信される衛星電波Saを用いたシステムである。比較部27は、端末1及び通信機9の通信が確立した場合に、端末1で取得された第1位置情報Da1と、被操作体2で取得された第2位置情報Da2とを比較する。判定部28は、比較部27の比較結果を基に、確立した通信の継続を許可すべきか否かを判定する。【選択図】図1
