Post-Quantum Cryptography X.509 Certificate
Abel C. H. Chen · 2024
In recent years, with the development of quantum computing, mainstream cryptographic algorithms in current PKI systems have gradually become threatened. In light of this, this study explores post-quantum cryptography X.509 certificate formats and discusses and implements solutions. The study compares mainstream cryptographic algorithms (including RSA and ECDSA) with post-quantum cryptography standard algorithms (including Falcon, Dilithium, SPHINCS+), comparing the efficiency of certificate production, signature generation, and signature verification. Finally, recommendations are made regarding post-quantum cryptography X.509 certificate solutions.
