Learn to transform legacy PKI infrastructure into a crypto-agile, post-quantum ready system in this 26-minute conference talk. Explore the critical challenge of adapting Public Key Infrastructure to quantum computing threats while leveraging NIST-standard algorithms like ML-KEM and ML-DSA. Discover a comprehensive three-part strategic framework: assess cryptographic exposure across TLS, S/MIME, code signing, and device identity systems; implement crypto-agility and automation through hybrid certificates, short-lived certificates, and ACME-based issuance models; and align PKI governance with emerging standards from NIST, ETSI, CAB Forum, and IETF. Gain practical insights for evolving existing PKI systems without complete infrastructure overhaul, focusing on automated certificate lifecycles and future-ready security architectures that maintain digital trust in the quantum era.
