NIST PQC Standards (FIPS 203/204/205)
Module-Lattice-Based Key-Encapsulation Mechanism. Replaces RSA and ECDH for key establishment.
Use: Key exchange / encapsulation
Module-Lattice-Based Digital Signature Algorithm. Replaces RSA and ECDSA for signatures.
Use: Digital signatures
Stateless Hash-Based Digital Signature Algorithm. Hash-based fallback with no lattice assumption.
Use: Digital signatures (conservative)
Migration Roadmap (NIST IR 8547)
Identify and inventory all quantum-vulnerable cryptographic assets across the enterprise.
Pilot PQC algorithms (ML-KEM, ML-DSA) in non-production environments. Test interoperability and performance.
Deploy PQC algorithms in production systems. Implement hybrid (classical + PQC) transition mode.
Complete migration to PQC standards. Deprecate and remove all quantum-vulnerable algorithms.
NIST deprecation of quantum-vulnerable algorithms. All new systems must use PQC.
NIST disallowance of quantum-vulnerable algorithms. Full PQC migration required for compliance.
