摘要

针对VANETs中认证开销大与隐私泄露风险等问题，提出一种融合联盟链与私有链的双区块链隐私保护认证方案，并引入短签名与部分同态加密技术，以兼顾系统的安全性、效率与隐私保护。安全性分析表明，该方案具备良好的隐私防护能力和抵御多种攻击的能力。仿真结果也进一步验证了本方案在计算和通信损耗方面的低负载特性，并在认证延迟、数据丢失率和系统吞吐量等指标上优于现有方案。

Abstract

To address issues like high authentication costs and risks of privacy leakage in VANETs

this paper proposes a dual-blockchain privacy-preserving authentication scheme that integrates consortium and private blockchains. The scheme also incorporates short signature and somewhat homomorphic encryption techniques to balance security

efficiency

and privacy protection. Security analysis demonstrates that the proposed scheme offers strong privacy preservation and resilience against various attacks. Simulation results further confirm that the scheme imposes low computational and communication overhead

and outperforms existing solutions in terms of authentication delay

packet loss rate

and system throughput.
