Abstract
The commercial adaptation of Vehicular Ad hoc NETwork (VANET) to achieve secure Intelligent Transportation System (ITS) heavily depends on the security guarantees for the end-users and consumers. Current VANET security standards address most of the security challenges faced by the vehicular networks. However, with the emergence of 5th Generation (5G) networks, and the demand for a range of new applications and services through vehicular networks, it is imperative to integrate 5G and vehicular networks. To achieve a seamless integration, various design and implementation issues related to 5G and VANETs must be addressed. We focus on the security issues that need to be considered in order to enable the secure integration of 5G and VANETs. More precisely, we conduct in-depth study of the current security issues, solutions, and standards used in vehicular networks and then we identify the security gaps in the existing VANET security solutions. We investigate the security features of 5G networks and discuss how they can be leveraged in vehicular networks to enable a seamless and efficient integration. We also propose a security architecture for vehicular networks wherein the current VANET security standards and 5G security features coexist to support secure VANET applications. Finally, we discuss some future challenges and research directions for 5G-enabled secure vehicular networks.
Introduction
Over the last couple of decades, the automotive industry has been the hotbed of technological innovation as a result of significant advances in computation, communication, and storage technologies. The main drivers behind such inno vations stem from the problems faced by the transportation systems. Every year, thousands of people lose their lives and billions of dollars are spent on medical bills and insurance costs. These huge costs have led to the development of a wide range of new transportation technologies which can enable a safe and comfortable driving experience and provide additional value-added services to both drivers and passengers [1]. In this context, the Intelligent Transportation System (ITS) promises a secure and reliable driving experience by employing vehicles to communicate with each other and with the environment that includes both infrastructure and the pedestrians. In other words, ITS is achieved through Vehicular Ad hoc NETwork (VANET) where vehi cles communicate with the environment through Vehicle-to-Everything (V2X) communication paradigm [2]. V2X includes Vehicle-to-Vehicle (V2V), Vehicleto-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), Vehicle-to-Cloud (V2C) communications and so on [3, 4].
