VANET Security and Privacy - An Overview

Abstract

Even though vehicular ad-hoc networks (VANETs) bring tremendous benefits to society, yet they raise many challenges where the security and privacy concerns are the most critical ones. In this paper, we provide a detailed overview of the state-of-the-art security and privacy requirements in VANET. Also, a brief of the approachesthat are proposed in the literature to fulfil these requirements is given in this paper. Besides that, a classification of the various VANET attacks based on the communication system layersisprovided in this paper. In addition, the different types of VANET adversaries and attackers arepresented here.In general, this paper aims to provide a good piece of information about VANET security and privacy, in order to be used as a tool to help researchers in this field in developing secure privacy-preserving approaches for VANET.

A Comparative Study on Trust-Based Security Routing Protocols for Vanets

“…Marvy B. Mansour et al (2018) presented an outlook on the importance of Security and Privacy in the VANETs. The authors have also given the categorization of attacks that can be carried out on these kinds of networks.…”

“…Perennially varying Topology, elevated Mobility, and Self-Administration are exceptional traits of Vehicular Ad-Hoc Networks (VANETs) (Mansour et al, 2018). Despite having these remarkable qualities, they also possess some confrontations (Jadhao and Chaudhari, 2018;Li, Song, 2015) .…”

“…The cautionary alerts are passed among the nodes to reduce destruction in case of hazardous situations. When a vehicle has an accident, this alert message will be forwarded to the emergency services through the intermediary nodes and the RSU to get the required medical support to the user (Mansour et al, 2018). This can even help some people who are in a hurry by addressing them to take a different route to reach their destination.…”

A Detailed Case Study on VANET Security Requirements, Attacks and Challenges

“…He sends the traffic jam messages or false messages to other vehicles. The purpose is to direct vehicles on road to go away from other route for the favor of attacker [11][12][13][14].…”

“…The attacker observes the target vehicle and sends harmful message to it. When it is overwhelmed with virus will take location of the vehicle and route of the vehicle in time constraint [9,14,18].…”
