The field of Vehicular-to-Everything (V2X) communication and Security Credential Management Systems (SCMS) is witnessing significant advancements aimed at enhancing security, privacy, and efficiency. A notable trend is the focus on improving the performance and scalability of authentication and key management schemes to support the dynamic and high-density environments of the Internet of Vehicles (IoV). Researchers are exploring innovative methods to streamline certificate management processes, with a particular emphasis on reducing execution times and enhancing privacy protections for connected vehicles. Additionally, there is a growing interest in developing hybrid cryptographic schemes that combine the strengths of Elliptic-Curve Cryptography (ECC) and Post-Quantum Cryptography (PQC) to safeguard against quantum computing threats while maintaining the efficiency required for V2X communications.
