Embodiment Construction
[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0053] The verification method based on the vehicle-machine multi-operating system provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the first operating system 101 and the second operating system 102 interact on the same terminal 103 . Exemplarily, the first operating system and the second operating system are communicatively connected through a virtual machine monitor (Hypervisor) and run on the same processor. For example, the verification method provided in this application can allow the first operating syst...

The invention relates to a verification method and device based on multiple operating systems of a vehicle-mounted terminal. The multi-operating system comprises a first operating system and a second operating system, and the method comprises the steps that the first operating system is started, an encrypted mirror image and an original mirror image of the second operating system are obtained through the first operating system, and the original mirror image comprises one or more mirror image blocks; decrypting the encrypted mirror image to obtain a decrypted mirror image; operation is carried out based on the original mirror image, for any mirror image block in the one or more mirror image blocks, the mirror image block is split from the original mirror image, and corresponding mirror image block operation information is obtained after operation is carried out on the mirror image block; and performing comparison verification on the mirror image block operation information and the decrypted mirror image. The second operating system is efficiently verified through the first operating system, the second operating system is prevented from being tampered, the safety of the verified operating system is guaranteed, and the system verification efficiency, the vehicle safety and the user experience feeling are improved.
Description
technical field [0001] The present application relates to the technical field of vehicle safety, in particular to a verification method and device based on vehicle-machine multi-operating systems. Background technique [0002] With the rapid development of the automotive technology field, a large number of in-vehicle infotainment products are installed in the car to meet the diverse needs of users. Car machine refers to the abbreviation of in-vehicle infotainment products installed in the car, which can realize information communication between people and cars, and cars and the outside world. When the vehicle-machine system is updated, the vehicle system settings may be tampered with, resulting in changes to the vehicle's security mechanism, and the vehicle is threatened by security. Therefore, the safety of the vehicle-machine system is the basis of vehicle driving safety, and it is necessary to ensure that the vehicle-machine has not been tampered with before the vehicle ...
