An Efficient Session Initiation Protocol for Secure Communication in Vehicular Ad-hoc Networks

Abstract

Vehicular Ad Hoc Networks (VANETs) are used for communication between vehicles and have a large number of applications such as road safety, entertainment and traffic control. VANETs provide information to the drivers regarding safety alerts on time. Security is one of the major concerns in VANETs as nodes in VANETs have high mobility. So, it is a challenging task to design an efficient solution for secure communication in VANETs due to high mobility of nodes. In literature, many authentication protocols have been proposed for secure communication in VANETs using Session Initiation Protocol (SIP). SIP is widely used for signalling, and establishing communication between different nodes in VANETs. SIP uses the concept of Voice over Internet Protocol (VoIP) for communication between vehicles. It uses Hypertext Transfer Protocol (HTTP) digest for identity authentication between different vehicles during communication. In this dissertation a SIP authentication protocol for various vehicles is proposed to address these issues. The proposed scheme is secure from various types of attacks. The security and performance analysis of the proposed scheme confirms the effectiveness of the scheme.
