融合区块链技术的隐私保护车联网数据共享方案
Blockchain-based privacy-preserving internet of vehicles data sharing scheme
摘要
Abstract
The internet of vehicles(IoV)continuously generates various types of data,including vehicle performance and information transmission data.Sharing these data among vehicles can enhance driving safety and improve the quality of intel-ligent transportation services.However,IoV data sharing faces numerous challenges,such as data tampering,central sys-tem failures,and privacy protection.To address these security concerns,this paper proposes a blockchain-based privacy-preserving data sharing scheme for IoV.A weighted threshold secret-sharing method is introduced to assign attribute values to vehicle members.Based on non-interactive zero-knowledge proof technology,a lightweight identity authentication protocol using attribute values is designed.This protocol pre-validates the identity of data requesters,preventing unauthorized access and safeguarding the privacy of vehicle members.Encrypted shared resources are stored using the distributed inter planetary file system(IPFS),with only storage addresses recorded on the blockchain,thereby reducing blockchain storage overhead.Experimental results demonstrate that the proposed scheme effectively addresses the limitations of existing solutions in terms of authentication,privacy protection,and flexible access control.It exhibits excellent performance and strong feasibility.关键词
