The embodiment of the invention provides a real-time GPS signal anti-spoofing detection alarm method, a vehicle-mounted TBOX and a system, and belongs to the technical field of vehicle-mounted information security. Based on physical consistency, a current predicted position of a vehicle is determined through a historical credible physical position and vehicle IMU data and speed data obtained by a vehicle-mounted TBOX in real time, and a physical distance between the current predicted position of the vehicle and a vehicle corresponding to a GPS signal and a current actual position is compared with a position offset threshold. And if so, carrying out GPS signal anti-cheating alarm. According to the embodiment of the invention, the computing power and data burden of the vehicle are reduced, whether the GPS signal is cheated or not can be effectively detected, the detection result is more accurate and comprehensive, the GPS signal of the vehicle is prevented from being cheated, people inside and outside the vehicle are warned, and the life and property safety of the people inside and outside the vehicle is protected.

    本申请实施例提供了一种实时GPS信号反欺骗检测告警方法、车载TBOX及系统,属于车载信息安全技术领域。基于物理一致性,通过历史可信物理位置以及车载TBOX实时获取到的车辆IMU数据及速度数据确定车辆当前预测位置,将车辆当前预测位置与GPS信号对应的车辆和当前实际位置的物理距离与位置偏移阈值相比较,若大于阈值则进行GPS信号反欺骗告警。通过本发明实施例,减小了车辆的算力与数据负担,可有效检测出GPS信号是否受到欺骗,检测结果更加准确全面,进而防止车辆GPS信号受到欺骗,对车内外人员进行告警,保护车内外人员的生命与财产安全。
