Abstract

The invention discloses a blockchain-based Internet of Vehicles architecture and a working method thereof. The Internet of Vehicles architecture includes interconnected vehicle entities, vehicle on-board units (OBUs), roadside units (RSUs), core networks, and blockchain networks. With the typical characteristics of decentralization, distribution, collective maintenance, and non-tampering, it can effectively solve the problems of centralization of the traditional Internet of Vehicles architecture and mutual distrust between entities. At the same time, it provides an undirected graph generation method, an identity privacy protection method and a location privacy protection method when the vehicle uploads beacon information, which solves the identity and location privacy leakage problem of the blockchain-based Internet of Vehicles architecture.

Description

technical field [0001] The invention belongs to the technical field of vehicle networking architecture, and in particular relates to a blockchain-based vehicle networking framework and a working method thereof. Background technique [0002] According to the latest research report by Counterpoint IoT Server, the global connected car market is expected to increase by 270% by 2022. As the number of vehicles increases exponentially, while bringing convenience to people's lives, it also raises new problems, such as traffic safety, environmental protection, privacy and security, etc. Therefore, the Internet of Vehicles has become a popular research content in the field of transportation, and it is expected to be able to change the problems existing in the existing transportation system and realize intelligent traffic management. In the vehicle network, through the summary and non-stop exchange of beacon information (Safety Beacon Message, SBM), to ensure that all vehicles in the ...
