In this research work, we present a specific method for authentication between the vehicle’s on-board unit (OBU) and roadside unit (RSU), which uses Physical Unclonable Function (PUF). This technology provides an identity for each vehicle unit that cannot be repeated. In this process, both units are registered with a reliable authority, which is the basis of certification. The process of mutual certification not only pays attention to safety, but has also been made faster with minimal resources. The validation of the protocol is checked via the ROR model and the AVISPA tool, which shows that this model is protected from common security threats. In addition, we will compare our proposed protocol with predefined algorithms on the basis of communication cost and also do the security analysis. This study offers a general description of the VANET authentication system that is practical, safe and skilled.
