Abstract A vehicular network serves as a sophisticated communication framework, facilitating seamless interaction between vehicles and the surrounding roadside infrastructure. This infrastructure comprises stationary nodes like roadside units (RSUs), traffic lights, road signs, toll booths, and more. These RSUs act as communication hubs, empowering vehicles to access and exchange real-time data regarding traffic status, weather conditions, road hazards, and other pertinent information. Through these components, functions like traffic management, emergency response, smart parking, autonomous driving, and public transportation are bolstered, leading to enhanced road safety, reduced congestion, and an improved driving encounter. These enhanced driving experiences can be intentionally disrupted by cyber attackers, potentially resulting in fatal accidents or congestion. One prevalent method utilized by such adversaries is wireless jamming attacks where attackers employ jamming devices to emit high-powered radio signals on the same frequency that the vehicular network is using. This interference leads to communication disruptions, causing delays or even complete prevention of legitimate data exchange with vehicles. Consequently, vehicles lose the capability to react to obstacles, emergency services, and crucial warning messages, culminating in severe outcomes. This security vulnerability poses a substantial threat to transportation system safety and efficiency.
This presentation intends to discuss a comprehensive overview of the vehicular network ecosystem, security measures, and strategies essential for ensuring and preserving the integrity of vehicular communications systems.
