Security Threats and Privacy Issues in Vehicular Ad-Hoc Network (VANET): Survey and Perspective

Abstract

Contribution/Originality: This study is one of the very few studies which have investigated security and privacy issues in VANET. We carried out a selective review of published work on this field between 2003 and 2015; and based on our findings, derived a new perspective, and categorized the security attacks on this type of network. 1. INTRODUCTION Vehicular Ad-Hoc Networks (VANETs) is an extension of Mobile Ad-Hoc Networks (MANETs). In Vehicular Ad-hoc Networks (VANETs), wireless-equipped vehicles form a network spontaneously while traveling along the road. Direct wireless transmission from vehicle to vehicle makes it possible to communicate even where there is no telecommunication infrastructure, such as base stations or access points of wireless dedicated access networks; vehicles can share up-to-date traffic information on the fly [1]. This is an emerging new technology to integrate the capabilities of new generation wireless networks to vehicles. The idea is to provide ubiquitous connectivity to vehicular nodes while on the move, and create efficient vehicle-to-vehicle communications that enable the Intelligent Transportation Systems (ITS) [2]. The network is based on node to node communication. A node can either be a user (vehicle) who desires certain information, or a Road Side Unit (RSU). The node, be it vehicles or RSU, can communicate and exchange data for purposes of information inquiry or distribution. The ultimate goal of VANETs is to enhance the driving experience and increase the level of safety for drivers [3-6]. This is achieved by allowing nodes within certain ranges to

Improving the detection of intrusion in vehicular ad-hoc networks with modified identity-based cryptosystem

“…Thus, many initiatives in academic and standardization societies have been inspired by this new model of communication [5]. Seven 10 MHz channels in the 5.9 GHz dedicated short-range communication (DSRC) band have recently been allocated by the Federal Communications Commission (FCC) of the United States of America (USA) to increase the protection and efficiency of the transport system [5], [6]. Six 10 MHz channels are dedicated to comfort applications (internet facility, information on the nearest restaurant, car park, filling station) in the new DSRC standard, and one channel is to safety applications.…”

“…Given the tremendous benefits expected from vehicular communications, just like any other wireless communication network, security has been a major challenge. Intruders can easily intercept, modify, and replay messages transmitted on the network or even impersonate other vehicles to broadcast incorrect information [6], [7]. Besides, the privacy of users on the network is also a challenge.…”

“…Besides, the privacy of users on the network is also a challenge. The ideal is that the travelling route of drivers should not be traceable by intruders through the message(s) sent or received by the vehicles on the network [8], [9]. Consequent to these security challenges in VANETs, it has received due attention from researchers, and the use of identity-based cryptosystem (IBC) to provide this security [10]- [12].…”

Self-Organized Network Management and Computing of Intelligent Solutions to Information Security

“…Because external attackers are not part of the system, they do not have the key of the entire system and cannot decrypt and sign messages, but they can obtain relevant information and use it for traffic and information analysis. Authorized and unauthorized information users are semi-trusted, which means that they will try their best to obtain some sensitive additional information from the query results and evidence (Ajulo et al, 2018).…”

The Model of the Drone System Design for a Multi-recording of the 360-degree Video and Real-time Merging Technique

“…The demand and utilization based on the drones are demanded through the increase of information gathering and utilization mainly with the 4th industrial revolution, and various studies for this purpose are being rapidly expanded worldwide [1,2]. SESAR's study suggests that by 2035, there is potential for in excess of 400 000 drones with the majority flying beyond visual line of sight and many, including for delivery purposes, being demanded for in populated settings at these very low levels of airspace [3,13]. And also the utilization field will expand to various fields such as agricultural disaster prevention and facility inspection [4,5].…”
