PORTABLE TERMINAL DEVICE AUTHENTICATION SYSTEM, AND ON-VEHICLE DEVICE
PROBLEM TO BE SOLVED: To provide a portable terminal device authentication system and an on-vehicle device that improve security of authentication by adjusting the strength of an authentication signal to be transmitted.SOLUTION: A portable terminal device authentication system includes an on-vehicle side control unit that generates a plurality of instruction signals having different duty ratios and supplies the instruction signals to an on-vehicle side transmission unit correspondingly to a request signal. The on-vehicle side transmission unit generates authentication signals having signal strength corresponding to the duty ratios of the supplied plurality of instruction signals and transmits the request signal including the authentication signals to a portable terminal device. The on-vehicle side control unit or a portable side control unit, on the basis of a processing result of the portable side control unit, determines the validity of an on-vehicle device or the portable terminal device.SELECTED DRAWING: Figure 1
【課題】送信する認証用信号の強度を調整して、認証のセキュリティ性を向上させる携帯端末装置認証システム、および車載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の前記車載側制御部は、デューティ比が異なる複数の指示信号を生成し、前記生成した指示信号を前記リクエスト信号に対応させて前記車載側送信部に供給し、前記車載側送信部は、前記供給された複数の指示信号の前記デューティ比に対応する信号強度の認証用信号を生成し、前記認証用信号を含む前記リクエスト信号を携帯端末装置に送信する、前記車載側制御部又は前記携帯側制御部は、前記携帯側制御部の処理結果に基づいて、前記車載装置または前記携帯端末装置の正当性を判定する。【選択図】図１
