Developing Privacy Preservation and Authentication Schemes for Secure Vehicle to Vehicle Communication in Vehicular Networks

Abstract

In the last few decades, intelligent transportation systems (ITS) have become the most effective and efficient approach for making the current transportation systems more di-verse. ITS has been revolutionizedby theIoV that applies Internet of Things (IoT)concepts to impart greater value to traditional vehicular networks. A vehicular network is a subpart of IoV that incorporates new emerging technologies to exchange information securely and efficiently in the network. Vehicular networks are gaining importance as the number of services that they offer are increasing day by day. As the variety of the services being provided increases, various challenges arise while incorporating these services. The significant challenges that affect the performance of the vehicular network are excessive time-delay, the issue of data loss in case of any failure in the network, lack of robust security and privacy, and computation time. In this work, the focus is to handle various challenges in vehicular networks and providing effective solutions. Subsequently, to preserve vehicle privacy in the network, a pseudonym-based authentication scheme has been implemented in which pseudonyms are assigned to each vehicle in the network. To ensure security in the network, the information is encrypted by using matrix array symmetric key (MASK), digital signature algorithm (DSA) and intelligent water drop (IWD) scheme. This proposed security scheme handles many security attacks such as non-repudiation, key-guessing, modification, and replay. Furthermore, the delay minimization cover tree algorithm has minimized time-delay during vehicle-to-vehicle communication. Obtained results show that the proposed scheme is more effective and efficient as it reduces the time-delay during vehicular communication. Further, to ensure information protection in the vehicular network, Fully Homomorphic Encryption (FHE) with Reduced Round Advanced Encryption standard (RR-AES)have been amalgamated. By using this scheme, the computational overhead and operational cost
