PORTABLE TERMINAL DEVICE AUTHENTICATION SYSTEM, ON-VEHICLE DEVICE, AND PORTABLE TERMINAL DEVICE
PROBLEM TO BE SOLVED: To provide a portable terminal authentication system, on-vehicle device, and portable terminal device that are capable of improving security of authentication.SOLUTION: A portable terminal device authentication system includes an on-vehicle device and a portable terminal device. The on-vehicle device transmits a request signal including a plurality of authentication signals having different degrees of signal strength. The portable terminal device receives the request signal; discriminates the plurality of authentication signals on the basis of the degrees of signal strength of the plurality of authentication signals included in the request signal; for each discriminated authentication signal, counts reception time of the authentication signal; and transmits an answer signal including information showing the counted reception time to the on-vehicle device. The on-vehicle device determines whether or not information showing reception time of an authentication signal is included in a received signal; and, when information showing reception time is included, determines whether or not the received signal is the answer signal from the portable terminal device on the basis of the information showing the reception time of the authentication signal.SELECTED DRAWING: Figure 1
【課題】認証のセキュリティ性を向上させることができる携帯端末装置認証システム、車載装置、および携帯端末装置を提供すること。【解決手段】携帯端末装置認証システムは、車載装置が、信号強度が異なる複数の認証用信号を含むリクエスト信号を送信し、携帯端末装置が、リクエスト信号を受信し、リクエスト信号に含まれる複数の認証用信号の信号強度に基づいて、複数の認証用信号を判別し、認証用信号の受信時間を、判別した認証用信号ごとに計時し、車載装置に対して、計時した受信時間を示す情報を含めたアンサー信号を送信し、車載装置が、受信した信号に認証用信号の受信時間を示す情報が含まれているか否かを判定し、受信時間を示す情報が含まれている場合に、認証用信号の受信時間を示す情報に基づいて、受信した信号が、携帯端末装置からのアンサー信号であるか否かを判定する。【選択図】図１
