Securing Vehicular Ad-Hoc Networks: Detection and Identification Algorithm of MITM Attacks

Abstract

The communication between vehicles (V2V) and vehicles to infrastructure (V2I) plays a crucial role in the Vehicular Ad-hoc Network (VANET). Its aim is to enhance road safety, reduce traffic accidents, and improve traffic efficiency. This necessitates the exchange of critical information among vehicles, static roadside units (RSUs), and traffic control centers. This integration gives rise to Cooperative Intelligent Transport Systems (C-ITS). However, the latency in wireless communication can have adverse effects on safety. To address this, vehicle advancements have led to the formation of platoons, enabling better latency control and safer driving. Nonetheless, platooning also exposes vehicles to significant risks, such as Man-In-The-Middle (MITM) attacks. These attacks can result in message delays, juggling, and drop-offs, particularly affecting time-sensitive messages like accident notifications. This research paper focuses on analyzing the impact of MITM attacks that cause message delays and proposes measures to detect and sever connections with malicious vehicles. By establishing secure paths, this solution aims to enhance VANET security and optimize network performance.
