A blockchain-based trust management method for Internet of Vehicles

Abstract

The invention discloses a blockchain-based trust management method for Internet of Vehicles, which firstly calculates the received vehicle information credibility about events, uses the vehicle information credibility to judge the occurrence probability for each event, and generates information for sending information. Rating, upload the vehicle information rating to the nearby RSU; RSU calls the reputation value update method in the smart contract deployed on the blockchain to calculate the vehicle reputation value, and packs the calculated vehicle reputation value and the collected rating information into the district In the block; through the consensus mechanism combining PoW and PoS, it is guaranteed that the RSU with a greater change in vehicle reputation value will act as a miner node and release the block; Calculation, if the calculation results of most nodes are consistent with the data in the release block, the release block will be published to the blockchain to realize the trust management of the Internet of Vehicles. The invention ensures data security and improves the accuracy of event judgment in the Internet of Vehicles.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a blockchain-based trust management method for the Internet of Vehicles. Background technique [0002] The Internet of Vehicles mainly refers to the on-board sensors on the vehicle to transmit the dynamic information of the vehicle through wireless communication, and use the effective information in the calculation to provide different functional services for the vehicle, such as providing road information, weather information, traffic accident information, etc. With the steady increase in the quantity and quality of cars and the rapid development of computers, the process of vehicle automation has been greatly advanced. Due to the distributed network architecture of the Internet of Vehicles, the high mobility and universality of vehicles, the communication information of vehicles is more vulnerable to malicious attacks and errors, and the network secur...
