A Study of Security and Privacy in Vehicular Networks
With the rapid development in wireless communications and artificial intelligence in recent years, vehicles are equipped with various smart devices to have ubiquitous access to the internet. These smart vehicles can easily exchange information with surrounding objects, e.g. vehicles, pedestrians, and roadside units, which form an enormous network. These networks that built upon vehicles are named vehicular networks. As the key enabler of the Intelligent Transportation System, vehicular networks are envisioned to simplify the traffic management, improve road safety, and provide infotainment through various vehicular services, like vehicle to everything communications, vehicular fog computing, and the location-based services. However, vehicular networks are vulnerable to various security and privacy risks due to the wireless nature and the heterogeneous network attributes. How to provide security and privacy for vehicular networks has attracted great attentions from both industry and academia. So in this dissertation, we present a study of security and privacy of vehicular networks. Novel security and privacy solutions for different vehicular services are proposed, which address the security and privacy issues in vehicle-to-everything communications, fast handover, vehicular fog computing, and location-based services. The major contributions of this dissertation are shown as follows. 1) A secure and efficient privacy-preserving authentication scheme is proposed. The proposed scheme is based on a 5G software-defined vehicular network architecture and is proved to be secure and highly efficient. 2) A secure and efficient handover scheme is proposed to provide user uninterrupted vehicular service, which is critical for the frequent handover processes on high-speed vehicles. 3) An efficient group management and key distribution scheme is proposed for vehicular fog computing paradigm, which has a lower delay compared to other existing schemes. 4) A location privacy-preserving scheme is proposed for location-based services. With the proposed scheme, vehicle users can have real-time location-based services with accurate location information updates while preserving location privacy. At the end of this dissertation, we also point out open research issues in securing vehicular networks.
