Hybrid PQC Pseudonym for Vehicular Security

Description

Hybrid certificate methodology combining ECC with NIST-standardized Post-Quantum Cryptography (PQC) algorithms for vehicular communication security credential management systems (SCMS). Addresses quantum vulnerability of existing IEEE/ETSI standards while maintaining performance compatibility.

Activation Keywords

Core Methodology

Problem

IEEE and ETSI vehicular security standards (SCMS, BKE) rely on ECC (secp256k1, etc.), which is vulnerable to Shor's algorithm on quantum computers.

Solution: Hybrid Certificate Architecture

1. Dual-layer certificates: Combine ECC + PQC in a single certificate
