Vehicular Ad hoc NETwork (VANET) refers to an arbitrarily distributed network that is an integral subset of an Intelligent Transport System (ITS) and plays a vital role in providing convenient transportation, improving traffic safety, etc.VANETrealizes interactive communication through wireless medium among Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I). But, owing to the open/public communication nature of the wireless medium, it is often prone to different security threats. On the other hand, security is a significant aspect of theVANETframework. Thus, to address the security concerns, it is a common practice to establish an authentication and key agreement protocol among the communicating entities that ensures to provide the essential security requirements. However, after extensive literature survey, it is identified that all the existing authentication protocols are prone to different security threats. Moreover, the implementation of these protocols in real-world scenarios becomes impractical as it bears higher computation and/or communication overheads. Therefore, in this paper, we have proposed a trust-extended mutual authentication protocol for theVANETframework using a Puncturable Pseudorandom Function (PPRF). The informal and formal security verification of our protocol proves that it provides comparably higher security than the existing schemes. Further, our protocol is simulated using a well-known AVISPA simulation tool and the results show that our protocol is SAFE against replay and man-in-the-middle attacks. Additionally, in comparison to the existing literature our protocol provides higher computation and communication efficiency. Therefore, our protocol is reliable and secure for real-world implementation in theVANETframework.
