Abstract

The invention discloses a reinstalling prevention method, device and system, relates to the technical field of intelligent terminals and mainly aims to prevent illegal users from reinstalling an operating system so as to ensure normal use of a vehicle. The main technical scheme comprises the steps that after a to-be-verified bootloader is loaded, encryption calculation is performed on the to-be-verified bootloader, and the encrypted to-be-verified bootloader is verified; if verification succeeds, the to-be-verified bootloader is started, so that the to-be-verified bootloader continues to verify the legality of the operating system; and the to-be-verified bootloader verifies a digital certificate corresponding to the operating system and determines whether to start the operating system according to the verification result of the digital certificate.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a method, device and system for preventing flashing. Background technique [0002] With the development of social economy, the automobile industry has also developed rapidly, and has become an indispensable means of transportation in modern society China. At present, the car is equipped with an on-board operating system and has a fully open platform to provide users with various functional services, such as navigation and multimedia services. [0003] The inventor found that in the prior art, in order to obtain more operating rights in the operating system, users often take the method of forcibly flashing the machine. However, once the car machine system is forced to flash, the operating system will not work normally, which will seriously affect the safety of the car. Normal use. Therefore, preventing the user from forcing the operating system to flash is ...
