A Formal Ticket-Based Authentication Scheme for VANETs

Abstract
Vehicular ad hoc networks (VANETs) enable vehicles to exchange safety-related messages in order to raise drivers' awareness about surrounding traffic and roads conditions. Nevertheless, since these messages have a crucial effect on people's lives and as we cannot disregard the probability of attackers intending to subvert the proper operation of these networks, stringent security support should be applied on these messages before they can be relied on. Authenticating these messages before considering them is one of the key security requirements since it enables the receiver to make sure of the received message's integrity and the genuineness of its originator. This chapter presents a conditional privacy-preserving authentication scheme for VANETs.
