Vehicle-to-Everything (V2X) communication is crucial for the advancement of modern transportation systems, enabling real-time, dependable, and actionable data exchange. This technology facilitates the dissemination of Basic Safety Messages (BSMs) between vehicles and infrastructure, thereby enhancing safety, mobility, and environmental applications. Ensuring the integrity and accuracy of V2X data is vital for effective decision-making. This paper leverages the VEINS simulation framework to introduce 25 new sophisticated attacks aimed at four newly developed safety applications. These applications have been meticulously developed from scratch. Moreover, we introduce a multi-label attack generation technique, enabling multiple simultaneous attacks within a single data packet. For instance, coordinated attacks where speed adjustments are synchronized with changes in acceleration, increasing their complexity and detection difficulty. Central to our work are the advanced detection mechanisms designed to operate on Roadside Units (RSUs). These mechanisms employ trained algorithms to identify and neutralize malicious packets in real-time simulations, significantly bolstering the security of V2X systems. This comprehensive framework not only aims to reinforce the security infrastructure of V2X networks but also to guide standardization efforts and inform deployment strategies. Additionally, the implementation of digital certificates for digital signatures serves as a primary defense against malicious entities, ensuring the authenticity and integrity of V2X communications. Our objective is to provide the security community with an effective tool for developing a resilient and secure V2X ecosystem.
