Abstract

The present invention relates to a vehicle-mounted operating system and its implementation method. The system includes a user space and a kernel space. The user space includes an application program module, a whitelist management module, a configuration management module, and an audit log generation module. The kernel space includes a system Call layer, autonomous access control module, mandatory access control module, trusted measurement module, application program loading module and policy cache management module, the white list management module is connected with the application program module and configuration management module, and the trusted measurement module It is used to measure the credibility of the application program file, so that the kernel space can judge whether the application program can continue to be loaded. The invention realizes the measurement of the boot program and the boot file in the system startup process, and enhances the security of system resources.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a vehicle-mounted operating system and a method for using the same. Background technique [0002] The vehicle operating system is the interface between the user and the vehicle hardware, as well as the interface between the vehicle hardware and the upper-layer software. The functions of the vehicle operating system include managing the hardware, software and data resources of the vehicle system, controlling the operation of applications, improving the man-machine interface, providing support for the upper software, allowing the resources of the vehicle system, and receiving data, signals, audio, Video plays its role to the maximum, providing various forms of user interface (UI), enabling drivers to have a good driving environment, and effectively providing assisted driving, semi-autonomous driving, and even autonomous driving. [0003] With the rapid development of technologie...
