车载网中一种基于区块链的隐私保护数据聚合系统
A Blockchain-based Privacy-preserving Data Aggregation System for Vehicular Networks
摘要
Abstract
Aiming at the privacy risks and challenges of data aggregation in vehicular networks,this paper proposes a secure and anonymous data aggregation scheme based on blockchain in vehicular networks.The scheme integrates cloud computing with blockchain and designs a blockchain-based data aggregation system that enables efficient and secure data collection and analysis in vehicular networks.The solution uses key escrow resilience to ensure the security of the keys in the system,preventing the security issues previously caused by third-party key generation.Additionally,the scheme employs a two-stage data aggregation process to achieve fine-grained data aggregation,providing effective support for cloud service in vehicular networks.Security analysis and performance evaluations demonstrate that the proposed scheme is secure and offers higher computational and communication efficiency.关键词
