To provide an unauthorized communication prevention system and unauthorized communication prevention method that are capable of improving the security against unauthorized communication using a relay device.SOLUTION: An unauthorized communication prevention system 23 is used for an authentication function (authentication system 5) in which the operation of a device 4 of a subject 2 is permitted or executed when a terminal 1 is authenticated by a first communication between the terminal 1 and the subject 2. A monitoring section 29 monitors a second communication conducted between the terminal 1 and a router 25 as a difference communication from the first communication. A restricting section 30 restricts the operation of the subject 2 by the terminal 1 when the user has no intention to operate the subject 2 based on the monitoring results of the monitoring section 29.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を提供する。【解決手段】不正通信防止システム23は、端末1と被操作体2との第1通信によって端末1が認証された場合に被操作体2の機器4の作動が許可又は実行される認証機能(認証システム5)に用いられる。監視部29は、第1通信とは別の通信として端末1及びルータ25との間で実行される第2通信を監視する。制限部30は、監視部29の監視結果から、ユーザに被操作体2の操作意思がない場合に、端末1による被操作体2の操作を制限する。【選択図】図1
