SMMAP: Secure MAC-based Mutual Authentication Protocol for IoV

Internet of Vehicles (IoV) is the emerging domain in the Intelligent Transportation System (ITS), which facilitate synergic decision from the human being involved in the network and has been a focus of research in the past few years. IoV has the capabilities of large-scale data sensing, collection, and sharing of information between vehicles to the roadside unit and other smart nodes in the environment, allowing dynamic and spontaneous communication. However, these communications in IoV are more prone to security attacks and still face enormous challenges in the aspect of security and privacy. This paper presents an effective and lightweight Secure MAC-based Mutual Authentication Protocol (SMMAP) for IoV and a mechanism for secure communication between vehicles and other smart units of IoV. We provide a rigorous proof of security and authenticity for the proposed SMMAP scheme using the BAN logic. Qualitative and quantitative analysis has been concluded in the paper, which depicts that the SMMAP has better performance than other existing state-of-the-art schemes.
