Abstract
Recent advances in 5G-based disruptive technologies have ushered in a new smart era of interconnected mobility. Hence, smart city planners around the globe are facing the challenges of leveraging these new modalities of future mobility solutions. Some key innovations toward disruptive mobility are the next generation of the Internet of electric vehicles and ultra-high-speed 5G communication paradigms. However, adding security to IoEV data remains of great concern. In this study, we offer a novel secure blockchain and off-chainbased 5G mobility framework that enables the security of IoEV data at rest, in transmission, and in the storage medium. We address the 5G security vulnerabilities in the areas of mutual authentication and authorization, remote software updates, confidentiality and integrity protection, secure provisioning of 5G services, secure storage of IoEV and personal data, and location tracking. We present our experience in building the architecture and the implementation of the framework, in addition to the system evaluation results.
