COMMUNICATION FRAUD ENACTMENT PREVENTION SYSTEM
PROBLEM TO BE SOLVED: To provide a communication fraud enactment prevention system capable of accurately detecting fraud communication.SOLUTION: A transmission radio wave Sa is transmitted from a vehicle 1, and an electronic key 2 transmits a response radio wave Sb. The authenticity of the communication is determined by measuring delay time in the transmission and reception of the radio wave. The authenticity of the communication is determined while considering whether the communication uses altered carrier frequency by changing the carrier frequency of the radio wave at irregular timing when transmitting and receiving the radio wave for delay time estimation.SELECTED DRAWING: Figure 1
【課題】不正通信を精度よく検出することができる通信不正成立防止システムを提供する。【解決手段】車両１から送信電波Ｓａを送信して、電子キー２にその返信電波Ｓｂを送信させ、このときの電波の送受信に要した遅延時間を測定して、通信の正否を判定する。また、遅延時間推定用の電波の送受信時に、不規則なタイミングで電波の搬送波周波数を変更し、通信が搬送波周波数の切り替えも踏まえたものであるか否かも要素に加えて、通信の正否を判定する。【選択図】図１
