A block chain-based information sharing incentive method for Internet of Vehicles

Abstract

The present invention proposes a block chain-based information sharing incentive method for the Internet of Vehicles, using block chain technology to encourage more vehicle nodes to participate in the information sharing process and share real and effective information, thereby improving the timeliness of information shared by the Internet of Vehicles. Correctness: The group signature algorithm can be used to trace the malicious nodes that share false information while protecting the privacy of the vehicle nodes participating in the information sharing process, and improve the credibility of the shared information. The present invention can encourage the nodes to actively participate in the information sharing process and provide valuable information when selfish nodes are unwilling to share information and malicious nodes provide false information in the Internet of Vehicles, thereby improving the quality of information services.

Description

technical field [0001] The invention relates to a block chain-based incentive method for information sharing in the Internet of Vehicles, specifically relates to a group signature algorithm and block chain technology, provides an incentive method for information sharing in the Internet of Vehicles, promotes smooth information communication, and belongs to the field of information security technology . Background technique [0002] Information sharing in the Internet of Vehicles can provide users with real-time road safety information and satisfactory and comfortable information services during vehicle driving. However, selfish nodes and malicious nodes in the Internet of Vehicles will refuse to share information or share false information for their own interests. Seriously affect the performance of the Internet of Vehicles and reduce the quality of information services. Due to the lack of infrastructure, when the long-distance transmission exceeds the range of vehicle commu...

In the paper "Dual Incentive Data Forwarding Mechanism of Internet of Vehicles Based on Game Theory" published by Yang Shuxue et al. in "Computer Science and Exploration" in 2015, a dual incentive mechanism combining reputation reconstruction mechanism and game theory model was proposed. Promote selfish nodes to participate in the process of forwarding information. However, the method based on game theory needs to be based on strong assumptions, and its practical applicability needs to be considered

The paper "A Privacy-Preserving Blockchain Based Incentive Announcement Network for Communications of Smart Vehicles" published by Li, Lun and others in "Institute of Electrical and Electronics Engineers" proposed a blockchain-based incentive mechanism, which is based on blockchain technology and The ring signature algorithm is used to motivate vehicles to participate in the communication process, but this method is relatively complex, and the traceability process requires the participation of RSU or public transportation, and the high cost of deploying RSU has certain limitations, and this method does not consider users Active sharing of information
