A Privacy-Preserving Approach to Vehicle Renting and Driver Accountability in VANETs

Vehicular Ad Hoc Networks (VANETs) play a crucial role in the evolution of Intelligent Transportation Systems. The problems of renting and drivers’ accountability still need to be answered in VANETs. Existing proposals do not consider renting vehicles, and there is no distinction between renters and owners. This paper proposes privacy-preserving rental and accountability protocols to address these problems. The proposed rental protocol outputs an agreement between an owner and a renter, which allows the renter to unlock and drive the vehicle. The privacy-preserving accountability protocol offers a robust solution for detecting and mitigating malicious behavior in VANETs. It provides a platform for holding entities accountable for their actions without violating their privacy. The paper demonstrates that our solution successfully meets the pre-set security and privacy requirements in VANETs. These findings suggest promising potential for improving future vehicular networks’ safety, efficiency, and performance.
