Vehicle safety communication method and device, vehicle multimedia system and vehicle

Abstract

The invention discloses a vehicle safety communication method and device, a vehicle multimedia system and a vehicle. The vehicle comprises an open system, a safety chip, and an enclosed system. The open system and the enclosed system are connected by the safety chip. The method applied to the safety chip includes: a first control instruction from the open system is received, wherein the first control instruction includes encryption control data; the encryption control data in the first control instruction are decrypted; when decryption is done successfully, decryption control data are obtained; the encryption control data in the first control instruction are converted into decryption control data to form a second control instruction and the second control instruction is sent to the enclosed system, so that the enclosed system controls a vehicle to execute a target operation based on the second control instruction. Therefore, security during vehicle networking communication can be improved.

Description

technical field [0001] The present invention relates to the field of Internet of Vehicles, in particular to a vehicle safety communication method and device, a vehicle multimedia system and a vehicle. Background technique [0002] With the development of large-screen in-vehicle multimedia and the popularity of Internet of Vehicles and 4G and WIFI hotspots, in-vehicle multimedia has gradually become another important mobile terminal system for car owners. More and more entertainment and multimedia needs. At present, many in-vehicle multimedia are equipped with 4G modules and WIFI modules, which can be connected to the Internet and allow customers to install their own preferred APP applications. In addition, with the development of big data and cloud services, the technology of remote control of vehicles has emerged. Vehicle-mounted multimedia is the carrier for cloud services, but this will bring great security risks to customers, because vehicle-mounted multimedia and other...

Problems solved by technology

In addition, with the development of big data and cloud services, the technology of remote control of vehicles has emerged. Vehicle-mounted multimedia is the carrier for cloud services, but this will bring great security risks to customers, because vehicle-mounted multimedia and other components of the vehicle There is communication and interconnection of components, and the car multimedia will send out many commands to control other parts of the vehicle. Once connected to the Internet, the car multimedia is just like a computer and mobile phone, which is vulnerable to the invasion of malicious programs. Criminals will remotely simulate the cloud server to send messages to the car. wrong command
