基于智能合约信誉管理的VANET数据共享隐私保护方案
Privacy protection and reputation management scheme in VANET data sharing
摘要
Abstract
To address the privacy and security challenges in data sharing within VANET,this paper proposed a privacy pro-tection scheme based on reputation management.The scheme integrated distributed storage via IPFS and smart contracts to en-sure data traceability and immutability.By introducing a reputation mechanism and employing homomorphic encryption to pro-tect feedback ratings,the system enabled dynamic updates of user reputation scores,effectively mitigating privacy leakage risks caused by malicious behaviors.Leveraging a lightweight data processing mechanism,the proposed scheme was particular-ly suitable for resource-constrained VANET environments.Experimental results demonstrate that,while maintaining the same level of privacy protection,the scheme outperforms existing methods in terms of computational and communication overhead.关键词
