Ring Signature Based Lightweight Dual Authentication Framework for Vehicular Adhoc Network

Abstract

Vast growth of vehicles around the world has led to various scientific research studies to provide faithful and secured communication in a Vehicular Ad-Hoc Network (VANET) and assure human safety along with preventing driver’s privacy. Traditional schemes provide solutions to the security issues with a trusted central authority guarantying the initial security solution. Trust and privacy remain a targeted issue due to the uniqueness in the VANET structure concerning just single point authentication. Therefore, to guarantee secured communication and preserve privacy, this paper has proposed a layered VANET communication architecture that achieves dual authentication to provide a higher level of security and maintain all vehicle communication. The proposed paper suggests an approach to provide lightweight encryption using Hyperelliptic Curve Cryptography (HECC) in reducing the overhead, and a step ahead to enhance security ensuring dual authentication (source and destination) in the network before any message transmission takes place. The focus of this paper is to consider both Vehicles to Infrastructure (V2I) and communication between Vehicle to Vehicle (V2V). The frameworks will emphasis in representing the advantages of the light weight encryption scheme along with dual authentication to maintain the security in the system.
