VANET security and forensics: Challenges and opportunities

Abstract

Vehicular Ad hoc NETworks (VANETs) are a key part of the Intelligent Transport Systems (ITS) as they constitute an intelligent transport network where vehicles and some infrastructure collaborate to exchange messages about traffic, accidents, etc. In such context, security becomes a key component to ensure that exchanged messages were not modified or inserted for example. Consequently, a wide variety of research contributions have been recently presented to cope with this issue. This paper presents a review of most recent papers dealing with security issues in VANETs. Hence, it presents an overview of VANETs and mainly their characteristics as well as their main applications. Then, the main security challenges faced by VANETs are introduced. This is done by first listing their main security requirements, second by establishing attackers' profiles, and their attacks and third by introducing some security solutions. Finally, the opportunities and challenges related to VANETs security are presented such as Trust, Internet of Vehicle, etc.

Secure Identity Management Framework for Vehicular Ad-hoc Network using Blockchain

“…In VANETs, there are mainly four types of communication as below [5]: Safety applications has two types of messages: event-driven and periodic safety messages [3]. Event-driven messages are generated at the occurrence of an emergency event like an accident or other unsafe situations.…”

“…Further, based on the scope of the attacks, it can be a local attack or a global attack. In local attacks, the affected area is limited, whereas in global attacks, the attack affects many nodes in the network, covering a large area [5]. • Authentication and privacy attacks: these types of attacks occur when unauthenticated vehicles access messages in the network or when the private information related to a vehicle is tracked [15].…”

“…Comfort applications provide features like weather information systems, gas/restaurant location, and price details, whereas safety applications support emergency warning systems, lane-changing assistance, and intersection coordination. to Infrastructure (I2I), or V2Xvehicle to any other internet-enabled device [5]. In the United States, IEEE has adopted the Dedicated Short Range Communication (DSRC) standardproviding seven 10 MHz channels at 5.9 GHz licensed bandwidth [3].…”

“…It is essential to ensure that only authenticated vehicles transmit valid messages; otherwise, it can adversely affect the lives of the drives or incur a substantial financial loss. According to [5] attacks in VANET can be:…”

“…In [5], Abassi et al has recognized some of the main security requirements in VANET as the following:…”
