The invention provides a vehicle-mounted operating system security detection method and device based on a virtualization technology. The method comprises the following steps: acquiring a heartbeat signal sent by a preset safety island system and a response signal sent by a corresponding vehicle-mounted operating system; wherein the safety island system is established based on a virtualization management program technology, and the heartbeat signal and the response signal both have a check code, a serial number, a timestamp, a CPU load and a memory occupancy rate; performing security detection on the vehicle-mounted operating system based on the heartbeat signal and the response signal to obtain a detection result; wherein the security detection comprises detection of a fault state and detection of a health state, the fault state is determined according to check code comparison, serial number comparison and timestamp comparison which are performed in sequence, and the health state is determined according to a CPU load rate and a memory occupancy rate of a response signal; and determining a selection scheme of the vehicle-mounted operating system based on a detection result. According to the scheme, the safety of the vehicle-mounted operation system can be effectively ensured.
本发明提供了一种基于虚拟化技术的车载操作系统安全检测方法及装置,其中方法包括:获取预设的安全岛系统发送的心跳信号和对应的车载操作系统发送的响应信号;其中,安全岛系统是基于虚拟化管理程序技术建立的,心跳信号和响应信号均具有校验码、序列号、时间戳、CPU负载和内存占用率;基于心跳信号和响应信号对车载操作系统进行安全检测,得到检测结果;其中,安全检测包括故障状态的检测和健康状态的检测,故障状态是根据依次进行的校验码对比、序列号对比和时间戳对比确定的,健康状态是通过响应信号的CPU负载率和内存占用率确定的;基于检测结果,确定车载操作系统的选用方案。本方案能够有效保证车载操作系统的安全性。
