🚗🔐✨ Hybrid Cryptography Enhances Security in Vehicle-to-Everything Communications. A new study proposes a hybrid certificate scheme combining Post-Quantum Cryptography (PQC) and Elliptic-Curve Cryptography (ECC) to address vulnerabilities in the Security Credential Management System (SCMS) for Vehicle-to-Everything (V2X) communications. As current ECC standards may be susceptible to quantum computing attacks, this innovative approach aims to leverage PQC’s quantum resistance while maintaining ECC’s efficiency and anonymity. Field tests conducted in New Taipei City demonstrated the effectiveness of this hybrid model, which addresses critical challenges such as packet length and signature efficiency. The study compares various existing hybrid schemes, offering a practical solution for the V2X industry amidst evolving security threats.
