Secure Vehicular Networking: Architectures, Applications, Attacks, and Challenges

Abstract

The rapid advancement in technology has significantly impacted the field of communication, particularly with the evolution of wireless technology. Among these developments, Vehicle-to-Everything (V2X) communications have emerged as a pivotal technology for intelligent transportation systems (ITS). This innovation facilitates a network wherein vehicles communicate with each other and their surroundings, sharing vital information about traffic conditions and potential hazards. This network is instrumental in enhancing traffic management through route optimization and congestion control, while also enriching passenger experience with on-board infotainment options. Designed with a focus on road safety and passenger comfort, V2X networks are equipped with advanced on-board sensors capable of detecting various scenarios such as road accidents, traffic congestions, and other obstacles. This chapter delves into the intricate details of vehicular communications, exploring their architectures, characteristics, applications, and governing standards. Furthermore, it elucidates the concept of communication security within these networks, outlining the existing models of attackers, classifications of attacks, and fundamental security mechanisms. The comprehensive overview aims to shed light on the critical aspects of securing vehicular networks in the ever-evolving landscape of communication technology.
