With NIST finalizing FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA), enterprise security teams are migrating legacy public-key infrastructure to post-quantum algorithms.
Cryptographic migrations take years. The post-quantum transition carries a unique urgency: 'harvest now, decrypt later' threats mean adversaries collect encrypted traffic today to decrypt once quantum hardware matures.
Our security track compiled an enterprise migration blueprint based on practitioner experience. The sequence prioritizes crypto-agility and discovery: mapping where RSA and ECC keys reside across microservices, legacy databases, and TLS endpoints.
The recommended default is hybrid deployment — combining classical algorithms with post-quantum standards (ML-KEM and ML-DSA) to maintain compliance while hedging against implementation bugs.
Testing reveals practical considerations: larger post-quantum key sizes and signature sizes affect network packet fragmentation and TLS handshake latency.
Our regional chapters are leading migration planning workshops to help engineering teams upgrade their cryptographic primitives.

Fascinating analysis. The empirical benchmarks on post-quantum lattice verification align with our lab results.
Will this architecture scale to multi-node clusters without memory bottlenecking?
