An Overview of Security in Vehicular Ad Hoc Networks

In recent decades, the importance of security has increased more and more especially in the field of research dealing with the Internet of Things (IoT) and implicitly ad hoc networks since they are part of it, considering they undergo several changes and that following these changes this area is exposed to several risks. Many researchers have shed light on different techniques to ensure the security of this intelligent universe. In this study, we identify the risks to which Vehicular ad hoc networks (VANETs) are exposed according to several criteria and metrics. For this purpose, we do bench-marking by carrying out research on the types of attacks that harm VANETs, after that we study the solutions proposed to ensure a high level of security in this type of network and finally we discuss these solutions to find out one that is most adapted to our teamwork and which is based on a relevant and recent technology. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
