Dual-system peripheral resource allocation method, terminal device and storage medium

Abstract

The invention discloses a dual-system peripheral resource allocation method, including that following steps of S0 carrying out the peripheral resource configuration file encryption, S1using the secureoperating system to decrypt the peripheral resource configuration file, 2 storing that peripheral resource configuration file in a secure storage area, S3 parsing the peripheral resource configuration file, obtaining a list of secure peripheral resources and a list of non-secure peripheral resources, S4 storing the list of non-secure peripheral resources in the memory sharing area, storing a listof secure peripheral resource in a secure storage zone, S5 enabling the secure operating system to access the secure storage zone, reading the list of secure peripheral resources, setting a peripheral resource to a security state according to its configuration information, and loading the device driver; S6 using the secure operating system to switch to the non-secure operating system; S7 using the non-secure operating system to read the non-secure peripheral resource list; and S8 loading or not loading the device driver according to the configuration information in the non-secure peripheral resource list.

Description

technical field [0001] The invention relates to the technical field of system security, in particular to a method for configuring peripheral resources of a dual system, a terminal device and a storage medium. Background technique [0002] With the continuous development of automotive intelligent network technology, nearly a hundred types of ECUs in the car are fully monitored and controlled through the internal vehicle network. Although this greatly improves the user experience, it has become a new target for hackers, making the car’s Security risks. In addition, the inherent lack of security protection in the internal system of the car will trigger a series of car attacks, such as remote hijacking of the car, intrusion into the car control system through the cloud, etc., causing the equipment on the car to generate wrong data, misleading and interfering with the driver, thus Causing serious consequences such as traffic accidents and car theft. [0003] Therefore, there is...
