| contents | This work explores the performance and scalability of a hierarchical certificate authority framework with automated certificate issuance employing post-quantum cryptographic (PQC) signature algorithms. The system is designed for compatibility with both classical and PQC algorithms, promoting crypto-agility while ensuring robust security against quantum-based threats. The proposed framework design expects minimal cryptographic requirements from potential clients, protects certificates of high importance against cross-dependent chains-of-trust and allows for prompt switching between classical and PQC algorithms. Finally, we evaluate SPHINCS$^+$, Falcon, and Dilithium variants in various configurations of certificate issuance and verification accommodating a large client base, underlining the trade-offs in balancing performance, scalability, and security. |
