By 2020, around 25 billion "things" will be connected to the Internet for a better society using different technological systems. Vehicle users have better experiences by collaborating the Internet of Things (IoT) and vehicular ad-hoc network (VANET) architectures, and this emerging field is called the Internet of vehicles (IoV). Thus, this architecture will play an important role in the industry, research organization, and academics for various public and commercial applications. However, the IoV structure should ensure secure and efficient performance for vehicular communications, else an attacker may interfere in the system. In this paper, we propose protected comprehensive data dissemination protocols (say IoVCom) using a one-way hash function for the IoV structure. Next, we discuss security strengths of the proposed schemes against various security attacks and measure performance results, i.e., communication overhead, computation time, storage cost, and energy consumption.
