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

Abstract

The invention discloses a vehicle secure communication method, a device, a vehicle multimedia system and a vehicle; the vehicle comprises an open system, a safety chip and a closed system; the open system and the closed system are connected through the safety chip; the method is applied to the safety chip, and comprises the following steps: receiving a first vehicle data order from the closed system, wherein the first vehicle data order comprises original vehicle data; encrypting the original vehicle data so as to obtain the corresponding encrypted vehicle data; replacing the original vehicle data in the first vehicle data order with the encrypted vehicle data, thus forming a second vehicle data order, and sending the second vehicle data order to the open system. The method and device can improve the vehicle networking communication safety.

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

Once maliciously intruded, criminals may obtain vehicle-related data information, resulting in vehicle data leakage, so it is necessary to carry out necessary information security guarantees when vehicle-mounted multimedia is connected to the Internet
