The invention discloses a vehicle-mounted system safety starting method and a vehicle-mounted system. The method comprises the steps that after a bootstrap program is started to run, the bootstrap program is started to transmit a preset partition mirror image file to a hardware security unit; the hardware security unit performs legality verification on a preset partition mirror image file transmitted by the startup bootstrap program; and if the verification is illegal, the system starting is interrupted. According to the scheme, before the system kernel is started, firstly, a preset partitionmirror image file is transmitted to a hardware security unit by a starting bootstrap program, the legality of the mirror image file is determined by the hardware security unit, and the system startingis interrupted under the condition that the mirror image file is determined to be illegal, so that the safety protection before the vehicle-mounted system is started can be realized, and the safety starting of the vehicle-mounted system is guaranteed; moreover, the implementation process of the scheme is simple and feasible, the protection execution efficiency is high, and large-scale applicationand implementation are facilitated.
本发明公开了一种车载系统安全启动方法及车载系统。其中,方法包括:启动引导程序运行后,启动引导程序将预设分区镜像文件传递至硬件安全单元;所述硬件安全单元对启动引导程序传递的预设分区镜像文件进行合法性验证;若验证不合法,则中断系统启动。本方案在系统内核启动之前,首先由启动引导程序将预设分区镜像文件传递至硬件安全单元,由硬件安全单元确定该镜像文件的合法性,在确定不合法的情况下中断系统启动,从而可实现对车载系统启动前的安全防护,保障车载系统的安全启动;并且,本方案实施过程简单易行,防护执行效率高,易于大规模应用与实施。
