The invention discloses a controller safety management method and device, a vehicle and a storage medium, the method is applied to a control system, the control system comprises a controller and a hardware encryption management module, a memory of the controller comprises a first partition and a second partition, and the method comprises the steps that when it is detected that the controller is powered on and started for the first time, the hardware encryption management module is started; calling a security starting function to store the first region verification key and the second region verification key to a hardware encryption management module; determining a starting function signature according to the secure starting function and the first region verification key, and storing the starting function signature to a hardware encryption management module; the application function is called according to the safe starting function in combination with the second area verification key and the application function signature control, so that safe starting of the controller is achieved, the problem that function safety cannot be guaranteed in the controller starting process is solved, the first partition is set to be a one-time programmable area, data tampering is avoided, and the safety of the controller is improved. Functions are prevented from being invaded, tampered and illegally injected by malicious software, and the equipment safety is ensured.
本发明公开了一种控制器安全管理方法、装置、车辆及存储介质,该方法应用于控制系统,控制系统包括控制器和硬件加密管理模块,控制器的存储器包括第一分区和第二分区,方法包括:当检测到控制器第一次上电启动时,调用安全启动函数将第一区域校验密钥和第二区域校验密钥存储至硬件加密管理模块;根据安全启动函数和第一区域校验密钥确定启动函数签名,并存储至硬件加密管理模块;根据安全启动函数结合第二区域校验密钥和应用函数签名控对应用函数进行调用,以实现控制器安全启动,解决了控制器启动过程中函数安全无法保证的问题,第一分区设置为一次性可编程区域,避免数据被篡改,避免函数被恶意软件侵入、篡改和非法注入等,保证设备安全。
