A Novel Privacy‐Preserving Authentication Protocol Using Bilinear Pairings for the VANET Environment

Abstract

With the rapid development of communication and microelectronic technology, the vehicular ad hoc network (VANET) has received extensive attention. However, due to the open nature of wireless communication links, it will cause VANET to generate many network security issues such as data leakage, network hijacking, and eavesdropping. To solve the above problem, this paper proposes a new authentication protocol which uses bilinear pairings and temporary pseudonyms. The proposed authentication protocol can realize functions such as the identity authentication of the vehicle and the verification of the message sent by the vehicle. Moreover, the proposed authentication protocol is capable of preventing any party (peer vehicles, service providers, etc.) from tracking the vehicle. To improve the efficiency of message verification, this paper also presents a batch authentication method for the vehicle to verify all messages received within a certain period of time. Finally, through security and performance analysis, it is actually easy to find that the proposed authentication protocol can not only resist various security threats but also have good computing and communication performance in the VANET environment.

A Scheme for Distributed Vehicle Authentication and Revocation in Decentralized VANETs

“…The proposed system follows a similar security threat model as mentioned in [28] and [4]. At first, all the entities in our system are separated into one of the following two categories.…”

“…Moreover, any other entity that is not registered and external to the system is referred to as an unauthorized entity. Based on curious, semi-trusted, and unauthorized entities to the system, we now categorize the potential threat into internal and external adversaries as also mentioned in [4] by Zhang et al…”

“…We adapt the specific security requirements outlined in section III-B as our security test cases. These requirements are then scrutinized against the designed threat model presented in section III-A, which corresponds with analogous models discussed by Mejri et al [28] and Zhang et al [4]. Using this approach, each subprotocol within our proposed scheme undergoes analysis to assess its adherence to the security requirements.…”

“…These mechanisms verify the legitimacy of communicating participants, promising the information exchanged is reliable and untampered. Ensuring the confidentiality of sensitive data, prompt responses to time-critical events, and safeguarding against a spectrum of threats, including insider and outsider attacks on public channels [4], present formidable hurdles in vehicular communication. The effectiveness of VANETs in enhancing road safety and traffic management hinges on the designed robust authentication protocols that can withstand these unique challenges posed by adversaries in public channels.…”

FC-LSR: Fog Computing-Based Lightweight Sybil Resistant Scheme in 5G-Enabled Vehicular Networks

“…To prevent RSU capture attacks and OBU intrusion assaults, they employed physical unclonable function and biological keys, and we devise a advantage embedding technique with dynamic pseudonym-ID to allow the TA to restore the identity of a compromised vehicle. Zhang et al [10] suggested a novel authentication mechanism based on bilinear pairings and short-lived pseudonyms, which the suggested authentication protocol can include features like authenticating the vehicle's identification and validating its sent messages. In order to solve the escrow issue and make certificates unnecessary, Imghoure et al [11] proposed an authentication with a privacy system that uses elliptic curve cryptography (ECC) instead of the more conventional Map-to-Hash function and bilinear pairing.…”
