Abstract

With the proliferation of embedded technologies and wireless capabilities, today’s vehicles are no longer isolated mechanical machines. They become part of a hyper-connected system -Intelligent Transportation Systems (ITS)- that has the potential to support multiple levels of autonomy and intelligence improving considerably the safety, efficiency, and sustainability of transportation networks. However, this raises new security issues that make the whole system prone to cybersecurity attacks that threaten both the safety and privacy of all road-users. This article gives a short background tutorial on the main security issues and the different attacks that hinder Intelligent Transport Systems. To enable secure and safe ITS applications, this article provides a comprehensive analysis of existing solutions and highlights their strengths and limitations. Finally, this survey presents key challenges in the field, and discusses recent trends that must be factored in by researchers, implementers, and car manufactures to improve the security of ITS.

Highlights

In recent years, Intelligent Transport Systems (ITS) have gained increasing attention as a promising field of research in academia and within standardization bodies, such as the Internet Engineering Task Force (IETF)
A few studies have focused on the plethora of security issues in Intelligent Transportation Systems (ITS) and their mitigation
We have analyzed security issues in ITS based on recently published articles to identify the root causes of vulnerabilities

Summary

INTRODUCTION

Intelligent Transport Systems (ITS) have gained increasing attention as a promising field of research in academia and within standardization bodies, such as the Internet Engineering Task Force (IETF). Huang et al [19] provide an in-depth review of the state-of-the-art solutions concerning security and privacy for V2X communications Both contributions did not cover new emerging security solutions (e.g., machine learning-based defense mechanisms and 5G-V2X security technologies). To the best of our knowledge, there is no survey that fully addresses the major aspects of ITS security including newer challenges and technologies, and the corresponding security solutions In this regard, this article presents a systematic review that aims to fill this gap through an in-depth analysis to cover recent advancements in ITS security. We cover recent publications (in the last seven years) from Q1 journals [28] (see Figure 1); the objective is to provide a detailed security analysis where vulnerabilities are surveyed and potential attacks are discussed.
