A blockchain-based data security communication method for Internet of Vehicles nodes

Abstract

The present invention relates to a block chain-based data security communication method for Internet of Vehicles nodes, which divides the entire network into cellular areas of the same size, and designs the alliance chain of the Internet of Vehicles and the inter-area public chain in units of areas to ensure data traceability. Improve the efficiency of data consensus; in the process of vehicle data communication, use vehicle identity authentication to ensure mutual trust between nodes, and divide the data into ordinary data and emergency data according to the urgency of the data. Inter-area communication, different data classification adopts different block structures, which improves the efficiency of data consensus; at the same time, it also considers the movement of the nodes of the Internet of Vehicles, adopts an improved and practical Byzantine fault-tolerant consensus method, and realizes the data security communication of the nodes of the Internet of Vehicles. Protect against data security risks brought about by centralized data storage. The invention has fast consensus speed, can protect data security and information privacy, reduces data storage space, and has high communication efficiency.

Description

Technical field: [0001] The invention relates to the technical field of block chains, in particular to a block chain-based method for secure communication of vehicle network node data. Background technique: [0002] In recent years, intelligent vehicles have increasingly occupied an important position in the automotive market. The Internet of Vehicles is one of the core technologies of intelligent vehicles. Its development can promote intelligent transportation and provide convenient information services. However, it periodically broadcasts information such as its current location, speed, and acceleration to surrounding neighbors, which poses a potential threat to vehicle data security. The existing Internet of Vehicles architecture is centralized, relying on trusted third-party entities to centrally manage vehicle information. However, once the centralized entity is attacked, it will bring serious data security risks and cause privacy leakage such as identity, location, an...

AI Technical Summary

Problems solved by technology

However, these methods do not consider the classification of data, and it is difficult to use blockchain technology to efficiently process the data of large-scale nodes of the Internet of Vehicles in real time.

[0005] To sum up, the existing block chain-based vehicle networking node data security communication methods have problems such as storage and maintenance difficulties, low communication efficiency, real-time processing difficulties, and potential safety hazards.
