Network connection automobile information security system based on blockchain

Abstract

The invention relates to a blockchain-based networked automobile information security system, and the system comprises a region edge cloud sub-platform, a vehicle-mounted mobile terminal and a cloud control security platform; the vehicle-mounted mobile terminal is used for acquiring abnormal driving data of an automobile and sending the abnormal driving data to the corresponding region edge cloud sub-platform; the area edge cloud sub-platform is used for obtaining target abnormal driving data, sending the target abnormal driving data to a cloud control safety platform, and storing the abnormal driving data; the cloud control safety platform is used for obtaining a target safety event corresponding to the target abnormal driving data, generating a target defense instruction corresponding to the target security event, and sending the target defense instruction to the area edge cloud sub-platform. According to the invention, the regional edge cloud sub-platform carries out distributed storage on abnormal driving data through blockchain storage, and the cloud control security platform carries out centralized analysis, early warning and defense, so the information security of networked automobiles can be timely and effectively ensured.

Description

technical field [0001] This application relates to the field of automotive intelligent network technology, in particular to a blockchain-based networked vehicle information security system. Background technique [0002] Intelligent networked vehicles are vehicles that sense the surrounding environment and realize autonomous cruise without the driver's control or a small amount of control. In the future, smart transportation and smart cities will use more and more connected and autonomous vehicles. [0003] With the continuous improvement of functions such as automatic driving and audio-visual entertainment of intelligent networked vehicles, more and more parts are accumulated in the car and a huge amount of data is generated, including: car control data, car usage data, car performance data, User data, environment data, working condition data, etc. At present, vehicle manufacturers usually introduce remote terminal equipment to transmit vehicle safety data to the networked ...

AI Technical Summary

Problems solved by technology

However, most networked data platforms can only query historical information after a security incident or a failure event, and reverse derivation and tracking to find the cause of the security incident or failure event, and cannot achieve real-time early warning.

On the other hand, due to the rapid development of Internet of Vehicles technology, it is foreseeable that when millions or tens of millions of vehicles are connected to the Internet of Things platform, a large amount of data will be stored in the Internet of Things platform, which will inevitably bring about the Internet of Things data platform. storage redundancy, which will bring new challenges to the effective storage of networked data and the information security of driving data
