Problems solved by technology

The traditional centralized structure has given great power to the certificate authority, and cannot guarantee the security of the data center. Attackers use certain attack methods to steal and forge users' private information, and tamper with messages at will, which is easy to cause a single point of failure, namely: trusted Security issues such as the authorization center being breached and unable to work normally

Abstract

The invention provides an Internet of Vehicles data exchange model based on a block chain. The model is based on an alliance chain and a relay chain (Relay-Chain), wherein each node in the model comprises a roadside infrastructure unit (RSU) and a vehicle unit (Onboard Unit), and each node in the model participates in the road side infrastructure unit (RSU) and the vehicle unit (RSU). By designingattribute access strategy matching between the nodes, unnecessary block generation is reduced, and the block chain overhead is reduced. The alliance chain and the cross-chain technology are combinedto realize message transmission between different alliances. And the realization process of the model is standard and easy to operate.

Description

technical field [0001] The invention belongs to the field of computer science and technology, in particular to a block chain-based data exchange model for the Internet of Vehicles. Background technique [0002] With the development of the city, people's demand for transportation is getting higher and higher, and the number of vehicles in the city is also increasing. The intelligent transportation system is playing an increasingly important role in improving the operation efficiency of the transportation system. Among them, Vehicle Networking (Vehicular Ad-hoc Network, VANET) is the core component of Intelligent Transportation System (Intelligent Transportation System, ITS). The Internet of Vehicles is a new self-organizing network composed of mobile vehicles with perception, computing, storage and wireless communication capabilities driving on traffic roads and basic communication facilities on the roads. It can intelligently control the whole process of traffic, effectivel...
