An Analytic Study of Security Solutions for VANET

Abstract

Vehicular ad-hoc networks (VANETs) are renowned form of mobile ad-hoc networks. In VANET, wireless device sends information to nearby vehicles, and messages can be transmitted from one vehicle to another vehicle or roadside infrastructure. So, using VANET can increase safety and traffic optimization. Similar to other technologies, in VANET there are some important and noticeable issues. One of the most important of them is Security. Since the network is open and accessible from everywhere in the VANET radio range, it is expected to be an easy target for malicious users. Therefore there is a need for optimizing the Security of vehicular Adhoc networks by Mitigating malicious attacks. This paper presents a review of security requirements, attacks and security challenges to implement the security measures in the VANET. Existing solutions proposed by different researchers are also reviewed and compared to find out the research gaps and scopes in the field of VANET security.

Security in VANET*

“…Existing message authentication and integrity procedures fail to secure networks from this attack because an attacker manipulates and deploys its own vehicle sensors to produce and transmit incorrect traffic information. [10,11] 4 Realization and simulation of the attacks Our task is to construct three types of network attacks in the vehicle environment, which will consist of several scenarios with different parameters. Subsequently, we evaluate the advantages and disadvantages of simulated attacks with a focus on QoS parameters (packet dropping, delay, throughput guarantee) and service availability.…”
