Abstract
Recently, there has been rapid growth in the Internet of things, the Internet of vehicles, fog computing, and social Internet of vehicles SIoV , which can generate large amounts of real-time data. Now, researchers have begun applying fog computing to the SIoV to reduce the computing pressure on cloud servers. However, there are still security challenges in SIoV . In this paper, we propose a lightweight and authenticated key agreement protocol based on fog nodes in SIoV . The protocol completes the mutual authentication between entities and generates the session key for subsequent communication. Through a formal analysis of the Burrows–Abadi–Needham (BAN) logic, real-oracle random (ROR) model, and ProVerif, the security, validity, and correctness of the proposed protocol are demonstrated. In addition, informal security analysis shows that our proposed protocol can resist known security attacks. We also evaluate the performance of the proposed protocol and show that it achieves better performance in terms of computing power and communication cost.

Summary
With the popularization and development of the world wide web, the Internet of things (IoT) [1,2,3], which is a network of Internet extension and expansion, has emerged. E data, processing, and application of fog computing are stored on scattered and weak devices, almost outside the cloud, so the computing power is not strong. In 2019, Ma et al [10] proposed a protocol for fog-based IoV networks, which realized authenticated key agreement. In 2021, Eftekhari et al [9] proposed a pairwise secret key agreement protocol using fog-based IoV, which was a threepart authentication protocol. We propose a lightweight and authenticated key agreement protocol based on three parties using fog nodes in an SIoV environment. In this protocol, vehicles and fog nodes authenticate each other with the help of a cloud server (CS) and establish a secure session key.
