To provide a tire condition monitoring system which can secure security of measurement data even when one-way low-speed wireless communication is applied between a sensor unit and an on-vehicle communication device, and an on-vehicle communication device.SOLUTION: An on-vehicle communication device 120 receives measurement data in which security is secured using a security key from a sensor unit 110. The on-vehicle communication device 120 relays the measurement data to a cloud server 300. The on-vehicle communication device 120 receives a result of security processing executed using a corresponding key corresponding to the security key by the cloud server 300 from the cloud server 300, and outputs the measurement data on the basis of the result of the security processing.SELECTED DRAWING: Figure 2

    【課題】センサユニットと車載通信装置との間において片方向の低速な無線通信が適用される場合などでも、測定データのセキュリティを確保し得るタイヤ状態監視システム及び車載通信装置を提供する。【解決手段】車載通信装置120は、セキュリティ鍵を用いてセキュリティが確保された測定データをセンサユニット110から受信する。車載通信装置120は、測定データをクラウドサーバ300に中継する。また、車載通信装置120は、クラウドサーバ300がセキュリティ鍵に対応する対応鍵を用いて実行したセキュリティ処理の結果をクラウドサーバ300から受信し、セキュリティ処理の結果に基づいて測定データを出力する。【選択図】図2
