Intelligent vehicle mounted device and secure communication method based on Internet of Vehicles

Abstract

The invention relates to the field of intelligent vehicle and information security, in particular to an intelligent vehicle mounted device and a secure communication method based on Internet of Vehicles. The intelligent vehicle mounted device comprises a microcomputer with large data mining capabilities based on the Linux system, a U shield, various vehicle mounted sensor modules, a communicationmodule, a extension motherboard, and an internal protection shell, and also comprises a matched communication authentication server and APP application; the microcomputer based on the Linux system isinserted with the U shield, and identity authentication operation is performed through the communication module and the communication authentication server. The authentication operation is performed by a cryptography standard signcryption scheme and a customizable signcryption scheme, therefore, the whole intelligent vehicle mounted device is in a highly secure communication environment, and the high security of the communication and data between the intelligent vehicle mounted device and the server is ensured.

Description

technical field [0001] The present invention relates to an intelligent vehicle-mounted device based on the Internet of Vehicles and the field of secure communication, in particular to a secure communication method and an intelligent vehicle-mounted device based on an information security signcryption protection mechanism in the data interaction process of the Internet of Vehicles. Background technique [0002] With the development of the urban transportation industry and technologies such as the Internet and artificial intelligence, motor vehicles, as an important means of transportation in modern society, are increasingly showing strong vitality. Among them, intelligent and networking technologies represented by assisted driving, automatic driving, and unmanned driving have become the hotspots of today's automotive technology innovation. With the rapid growth of the national economy, the number of motor vehicles is also increasing, which will inevitably lead to increasingly...

Problems solved by technology

At present, ordinary car models have 25 to 200 ECUs (Electronic Control Units, electronic control units). With the increase of car ECUs, hackers also increase the attack surface of cars. However, after being connected to the Internet, many of them are opened to the outside world. At the same time, due to the demand for intelligence, many sensors such as ultrasonic radar have been added to the car, which has increased the attack surface of the car.

[0003] At present, the black boxes of automobiles on the market generally use 8-bit or 16-bit single-chip microcomputers as processors, written in assembly language, and the program functions are relatively simple.

Although a few companies have developed the second-generation automotive black box with better functions, they do not use the operating system, so there are still defects in scalability, stability and security.

Moreover, the automotive devices on the market have not yet adopted the signcryption scheme of the data protection system of the cryptography standard model or the custom model, and various sensor data are still transmitted in plain text, which will expose the data collected by the automotive device, thereby Increase the safety hazard of driving
