Abstract

Vehicular Ad hoc Networks (VANET) broadcast messages regarding road and environmental conditions. Due to its design, VANET inadvertently introduced security and privacy issues. Many researchers have suggested various approaches to address these shortcomings as the deployment of VANET becomes more widespread. Nevertheless, these solutions could not address all the security and privacy shortcomings in VANET. Furthermore, the proposed approaches incur high costs in terms of computation due to the complexity involved in doing so sequentially. One of the significant approaches used in VANET security and privacy mitigation is identity-based schemes. This paper provides a comprehensive survey on VANETs and the entities involved, attack models, and an analysis of the security and privacy requirements for identity-based security and privacy schemes for VANETs.

Highlights

Vehicular Ad-hoc Networks (VANETs) is a subclass of Mobile Ad-hoc Networks (MANETs), where a vehicle is considered a mobility node
The main goal of this paper is to critically review identity-based security and privacy schemes based highlighting their strengths and weaknesses guided by security requirements, privacy requirements, resistance to cyberattack, and the evaluation metrics
ARCHITECTURE In this subsection, we describe the typical architecture of VANET in terms of entities and communications, as follows

Summary

Introduction

Vehicular Ad-hoc Networks (VANETs) is a subclass of Mobile Ad-hoc Networks (MANETs), where a vehicle is considered a mobility node. A VANET technology offers the drivers and passengers services such as Internet access, location-based services, and entertainment content [4]–[7]. A. OVERVIEW VANET communication offers drivers and passengers many transportation applications and provides unprecedented nonsafety information and safety services. When the vehicle collects and processes the exchange information involving V2V and V2I communications, it can increase the driver’s awareness of the driving environment, which enhances driving experiences and improve passenger comfort [20], [22], [34]. 1) Security requirements Due to the inherent characteristics of VANETs, it is vulnerable to different security attacks.
