Abstract

Vehicular Ad-hoc Networks (VANETs) enable communications between vehicles and infrastructure and are a key part of future Intelligent Transportation Systems. Significant advancements have been made in ensuring anonymous and secure communication within VANETs; however, integrating privacy-preserving vehicle rentals in VANETS is an unsolved problem. Existing protocols do not address the unique challenges posed by vehicle sharing and rentals, particularly regarding vehicle owners’ and renters’ privacy. This paper proposes a novel rental protocol within VANETs. Our solution is based on delegatable anonymous credentials and Non-Interactive Zero-Knowledge (NIZK) proofs. It allows drivers to securely delegate credentials to vehicles. This approach ensures that each vehicle broadcasts authenticated messages, verified through NIZK proofs, while the identity of the actual driver is verifiably escrowed to an inspector that can lift driver privacy in case of abuse. The latter property implements accountability into the system. Our protocol addresses the trust issues inherent in previous systems by providing a robust mechanism for privacy-preserving, accountable vehicle rentals in VANETs, enhancing the overall security and functionality of these networks.
