ABSTRACT

With the rapid development of Cellular Vehicle-to-Everything (C-V2X) communication systems, ensuring the security and integrity of data exchanged between vehicles and infrastructure has become a significant challenge. Identity authentication plays a crucial role in safeguarding these communications against threats such as identity spoofing and data tampering. Traditional certificate-based authentication methods, while effective, often suffer from performance issues, especially in high-speed, dynamic environments such as highways. In this paper, we propose a hybrid identity authentication system that combines physical layer recognition with certificate-based methods to enhance security and improve real-time performance in C-V2X systems operating in highway environments. The physical layer authentication leverages channel state information (CSI), signal fingerprints, and other radio-frequency characteristics to authenticate vehicles, providing an additional layer of security. This is combined with certificate-based public key infrastructure (PKI) to offer a comprehensive and robust identity verification process. The hybrid approach addresses the shortcomings of traditional methods by enhancing security while minimizing computational overhead and ensuring low-latency authentication. We discuss the challenges and opportunities in integrating these two authentication methods and highlight the potential impact of emerging technologies, such as 5G and machine learning, in optimizing the hybrid authentication process for C-V2X systems. Finally, we propose future research directions to further improve the efficiency, scalability, and robustness of hybrid authentication schemes in vehicular networks.
