Internet of Vehicles (IOV) is a section of the Internet of Things (IoT) which makes road transportation smart and provides security for the passengers traveling along the roads. Fog computation can be considered as a complement for IOV because it is close to the user and can communicate with Road Side Units (RSU) and process information with low latency. IOV employs a wireless network for message exchange which is a security flaw and an opportunity for the adversaries since that can modify the transmitted data. Thus, data authentication between the transmitter and the receiver has become a challenge in this context. We propose a secure mutual authentication protocol with the ability to key exchange in this paper, which does not use the hash function. We compared this design with other protocols in terms of security requirements and communication and processing costs. To the security analysis of the proposed Automated Validation of Internet Security Protocols and Applications (AVISPA) tool is used. The results show that the proposed protocol is more resistant to other methods of active and passive attacks but Computation and communication costs have increased.
