Privacy-Preserving Authentication Protocols in Vanet

연구 분야: Networking

학회: SN Computer Science

Vehicular Ad hoc Network (VANET) is a versatile and ad hoc network, where the vehicles must be authenticated before sharing any critical information. During authentication, privacy of the users must be preserved. There are several surveys on privacy-preserving authentication schemes in VANET. However, none of them are focused on the ability of the schemes to address different security issues and their robustness against security attacks. In this paper, we present a review on various privacy-preserving authentication schemes in VANET. These schemes may be categorized into several types like symmetric/asymmetric key cryptography-based schemes, digital signature-based schemes, ID cryptography-based schemes, pseudonym-based schemes, homomorphic encryption-based schemes, and blockchain-based schemes. A comprehensive study of the prominent schemes, with regards to their effectiveness in addressing different security issues and their robustness against possible attacks, has been performed. Open issue and scope for future work are also highlighted.
