Problems solved by technology

In the application of the flashing function of the diagnostic instrument of most commercial vehicles, the clear text transmission of the diagnostic instrument communication data lacks an identity authentication link. The lack of this security scheme will lead to hackers illegally flashing the controller equipment in the car through the diagnostic instrument, affecting the vehicle. normal use, deciphering the use of functional permissions, obtaining illegal benefits, and even endangering the safety of vehicles

Abstract

The invention discloses a vehicle flashing method, an Internet of Vehicles box, a vehicle and a storage medium, the method is applied to the Internet of Vehicles box, and the method comprises the following steps: sending a flashing request of a user side to a server, and if the vehicle information is in authorized data of the server, enabling the server to send an issued encrypted file flashing message to a user side; enabling a user side to send a flashing instruction to a vehicle-mounted computer of a vehicle, wherein the flashing instruction comprises vehicle networking box information, and if the vehicle networking box passes safety certification of the vehicle-mounted computer, an operation authorization request generated by the vehicle-mounted computer according to the flashing instruction is sent to a server; and sending an authorization file fed back by the server according to the operation authorization request and the encrypted flash file to the vehicle-mounted computer for flash, wherein the authorization file is used for decrypting the encrypted flash file by the vehicle-mounted computer. According to the embodiment of the invention, the vehicle flashing function and the information security of vehicle communication are realized.

Description

technical field [0001] The embodiment of the present invention relates to the field of information security technology, and in particular to a method for flashing a vehicle, a car networking box, a vehicle and a storage medium. Background technique [0002] With the continuous development of the Internet of Vehicles technology, the number of connected cars is increasing, and the attack surface is gradually increasing. There are more and more electronic components and network units on the car, and the car information network is gradually changing from a separate, closed The characteristic network has become a network connected to the Internet, but at the same time, connecting the car to the Internet also breaks the original closed ecology of the car control system, and introduces the security risks of the Internet into the car network. A popular target for hackers. The exposed information security issues are also gradually emerging. [0003] At present, domestic commercial ...
