The invention discloses a vehicle-mounted terminal information security risk control method based on traffic scene security. The method comprises the following steps of 1, collecting motorcade information; 2, researching a detection mechanism of a corresponding vehicle-mounted terminal based on the traffic system model; step 3, acquiring a vehicle-mounted terminal information security risk monitoring threshold in a security communication scene as an initialization standard of security detection; 4, acquiring a state variable in an attack scene; 5, enabling the road side unit to integrate the vehicle data information detected in the above step and then transmit the information back to the vehicle; and 6, comparing the security risk monitoring function value with an information security riskmonitoring threshold to judge whether the system is attacked or not. According to the vehicle-mounted terminal information safety risk control method based on traffic scene safety, in the vehicle driving process, information is judged continuously, attack information can be further expanded effectively, the universality is high, and reliability and effectiveness are higher when information recovery is carried out on roadside equipment.
本发明公开了一种基于交通场景安全的车载终端信息安全风险控制方法，包括如下步骤：步骤一，采集车队信息；步骤二，基于交通系统模型研究相应的车载终端的检测机制；步骤三，获取安全通信场景下的车载端信息安全风险监测阈值作为安全检测的初始化标准；步骤四，在攻击场景下获取状态变量；步骤五，路侧单元把上述步骤中检测的车辆数据信息整合后的信息再传回车辆；步骤六，将安全风险监测函数值与信息安全风险监测阈值进行比较判断系统是否发生攻击。本发明的基于交通场景安全的车载终端信息安全风险控制方法，在车辆行驶过程中，持续性地对信息进行判定，能够有效地将攻击信息进一步扩大，普适性强，对于路侧设备进行信息恢复更具可靠性和有效性。
