Abstract

Vehicular networks play an important role in the intelligent transportation systems which have gained technical supports from car industry. Due to the mobility and the broadcast nature of wireless communication, security of the vehicular networks is a critical issue for the academia and industry. Many solutions have been proposed to target the security provisioning. However, most of them have various shortcomings. Based on the elliptic curve public key cryptography algorithm, in this paper, we propose a new anonymous roaming authentication protocol for the Long Term Evolution-Advanced (LTE-A) supported vehicular networks. For a vehicular LTE-A network, an authentication protocol should be able to fulfill a variety of security requirements, which can be met by our proposal and proved by using Burrows–Abadi–Needham (BAN) logic. Compared with some existing solutions, our scheme has lower communication costs with stronger security functionality. The analyses on the security functions and the performance of the proposed solution show that our scheme is secure and efficient with ability against various types of malicious attacks.

Highlights

A vehicular ad hoc network (VANET) is a mobile self-organized network in the intelligent transportation system (ITS)
It is comprised of vehicle on-board units (OBUs), roadside units (RSUs), which are the fixed units deployed at sides of the road, the control center, etc
We have explored that some security schemes are vulnerable to impersonation

Summary

Introduction

A vehicular ad hoc network (VANET) is a mobile self-organized network in the intelligent transportation system (ITS). Recent research on vehicular network has focused on major five areas: (1) the collaborative security applications on the road safety for the vehicles involved [3], (2) data transmission, information distribution, and data collation methods, (3) traffic and vehicle movement modeling, (4) the physical layer and medium access control (MAC) layer communications, and (5) privacy and identity authentication. To remedy some of the weaknesses, [9] proposed a novel anonymous authentication scheme in the LTE networks It is shown in [15] that a recently proposed protocol named PairHand can outperform other protocols in terms of security and efficiency, which could be a potential candidate for the deployment in the vehicular networks. The ARHAP scheme works based on the elliptic curve public key cryptography to implement the secure and efficient handovers between the service and target eNodeBs in a LTE-A network.
