双区块链支持的隐私保护车联网数据分级共享方案
A Privacy-preserving and Dual Blockchain-enabled Hierarchical Data Sharing Scheme for Internet of Vehicles
摘要
Abstract
For the problems of single point of failure,low throughput,collusion attack and high computational cost in Internet of Vehicles(IoV)data sharing scenarios,a privacy-preserving and blockchain-based data sharing scheme for IoV(PBDSS)is proposed,and its core innovations are reflected in three areas:Firstly,blockchain is utilized to store data and manage key,which prevents data from being tampered and effectively resists collusion attack;Secondly,by outsourcing the complex decryption computation to the edge nodes,online/offline encryption is achieved,which reduces the computational cost of the vehicle;Finally,the design of a hierarchical data-sharing mechanism strikes a balance between security and efficiency.Security analysis and experimental results show that PBDSS has significant advantages in terms of security and performance compared with typical existing data sharing schemes for IoV.关键词
