Security of internet of vehicles in smart cities: authentication and confidentiality aspects

With the rapid development of smart devices, communication technologies, and network elements, vehicles become more autonomous, more connected, and more intelligent. Internet of vehicles (IoV) is a new area of the internet of things (IoT) equipped with powerful multi sensors platform, connectivity and communication technologies. The communication and the cooperation between vehicles and different IoT objects can increase security risks and make vehicles more vulnerable to serious attacks (authentication attacks, confidentiality attacks, availability attacks, routing attacks, and data authenticity attacks). In this paper, we propose security schemes to detect and prevent attacks in IoV system using software defined network (SDN) and elliptic curve cryptography (ECC); first, we identify IoV concepts, then we design a network model which illustrates the global IoV architecture, after that we propose an authentication and confidentiality schemes. Finally, we provide formal and informal proof to demonstrate that our schemes can resist against various attacks.
