A Zero-Knowledge Signature Framework for Efficient Post-Quantum Message Authentication in Cooperative Automated Driving
The ZKS-PQC framework replaces large post-quantum public keys and signatures with compact Zero-Knowledge Proofs (ZKP) for message authentication in V2X systems. This allows for communication efficiency while maintaining compatibility with older security systems. Experiments show acceptable processing times, enabling a smooth transition to quantum-safe cryptography without significant performance loss.
