PDRU: A Privacy-Preserving Dual Reputation Updating Scheme With Multi-Dimensional Feedback Scores in Vehicle Platoon

Summary

This paper proposes PDRU, a privacy-preserving dual reputation updating scheme for vehicle platoons. It uses a dual reputation model to resist single reputation attacks, and a multi-dimensional evaluation framework where following vehicles score the leading vehicle with weighted-average feedback. The authors report, through theoretical analysis and simulation, a strong balance between robustness, privacy, security, and efficiency, with lower computation and communication overhead on the Trusted Authority side.
