WIRELESS COMMUNICATION AUTHENTICITY DETERMINATION SYSTEM
To provide a wireless communication authenticity determination system which can more accurately determine unauthorized wireless communication to be formed with the use of a repeater.SOLUTION: A wireless communication authenticity determination system performs a distance measuring communication using the same UWB electric waves between a UWB transceiver 13 of a vehicle 1 and a UWB transceiver 32 of an electric key 2. A measured distance value calculation section 41 of the vehicle 1 calculates a measured distance value on the basis of the UWB electric waves used by the distance measuring communication. A reception signal strength calculation section 42 of the vehicle 1 calculates reception signal strength on the basis of the UWB electric waves used by the distance measuring communication. A communication authenticity determination section 43 of the vehicle 1 executes correlative authentication on the basis of whether or not there is a correlation between the measured distance value and the reception signal strength. When the correlative authentication is not established, the wireless communication authenticity determination system re-measures the measured distance value and the reception signal strength, and re-executes (re-tries) the correlative authentication, after switching an antenna provided to the UWB transceiver 13 of the vehicle 1 between antennas 13a, 13b.SELECTED DRAWING: Figure 1
【課題】より的確に中継器を使用した無線通信の不正成立を判定できる無線通信正否判定システムを提供する。【解決手段】車両１のＵＷＢ送受信機１３と電子キー２のＵＷＢ送受信機３２との間を同一のＵＷＢ電波で測距通信する。車両１の測距値算出部４１は、測距通信で用いられたＵＷＢ電波に基づいて測距値を算出する。車両１の受信信号強度算出部４２は、測距通信で用いられたＵＷＢ電波に基づいて受信信号強度を算出する。車両１の通信正否判定部４３は、測距値と受信信号強度との相関があるか否かに基づいて相関認証を実行する。相関認証が不成立である場合、車両１のＵＷＢ送受信機１３に設けられたアンテナを、アンテナ１３ａ，１３ｂの間で切り替えた後、測距値および受信信号強度を再度測定し、相関認証を再度実行（リトライ）する。【選択図】図１
