To provide an illicit communication prevention system and an illicit communication prevention method that can prevent unneeded interference from other communication machines during communication for checking position relation that is performed between a terminal and a communication machine.SOLUTION: A measuring unit 22b of a terminal 2 transmits a UWB distance measurement signal Sa to a communication machine 13 during distance measuring communication with the communication machine 13. At this time, a notification unit 26 notifies the communication machine 13 of authentication information Did that is registered in the terminal 2. The authentication information Did is, for example, a unique ID for a vehicle 1. When receiving a distance measurement signal Sa, an operation unit 27 of the communication machine 13 compares the authentication information Did that is registered therein with the authentication information Did that is received from the terminal 2. When these types of authentication information Did match, a measuring unit 22a of the communication machine 13 returns a UWB distance measurement signal Sb to the terminal 2.SELECTED DRAWING: Figure 1
【課題】端末及び通信機の間で行われる位置関係を確認する通信の際に、他の通信機からの不要な干渉を抑制可能にした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】端末２の測定部２２ｂは、通信機１３との測距通信の際、ＵＷＢ帯の測距信号Ｓａを通信機１３に送信する。このとき、通知部２６は、端末２に登録されている認証情報Ｄidを通信機１３に通知する。認証情報Ｄidは、例えば車両１の個別ＩＤである。通信機１３の作動部２７は、測距信号Ｓａを受信すると、端末２から受信した認証情報Ｄidを、自身に登録されている認証情報Ｄidと比較する。通信機１３の測定部２２ａは、これら認証情報Ｄidが一致する場合に、ＵＷＢ帯の測距信号Ｓｂを端末２に返信する。【選択図】図１
