FIPS 203 / 204

Post-Quantum Cryptography Migration & Java 27 Readiness Planner

Grounded on: Java 27 Release & JEP 527 • @Cointelegraph Source
Oracle Java 27 Architecture Context: JEP 527 introduces native hybrid post-quantum key exchange for TLS 1.3, pairing classical X25519/ECDH with NIST-finalized FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA) without breaking legacy clients.

Verification & Grounding Evidence

This planner models empirical cryptographic dimensions defined in NIST FIPS 203 (Module-Lattice-Based Key-Encapsulation Mechanism), FIPS 204 (Module-Lattice-Based Digital Signature Standard), and JEP 527 released in Oracle Java 27. Benchmarking data includes round-trip latency adjustments for enterprise microservice networks with TLS 1.3 dual-handshake key material.
