NIST publishes post-quantum cryptography transition guidance
Original title: NIST Officially Released Guidance for Transition to Post-Quantum Cryptography
NISTIR 8547 sets federal high-value key-establishment work for 2030 and signatures for 2031, with a 2035 overall target.
NIST released NISTIR 8547, Transition to Post-Quantum Cryptography Standards, on October 27, 2026. The report maps vulnerable cryptography to FIPS 203 ML-KEM, FIPS 204 ML-DSA and FIPS 205 SLH-DSA rather than adding a new algorithm. National Security Memorandum 10 keeps 2035 as the main federal completion target, while Executive Order 14412 moves high-value and high-impact systems to quantum-resistant key establishment by 2030 and signatures by 2031. Those deadlines do not automatically bind private businesses, though federal suppliers are told to assess customer requirements. Hybrid conventional and post-quantum deployments are allowed.
- The report cites harvest-now, decrypt-later collection of encrypted data.
- FIPS 203 covers ML-KEM shared-secret establishment.
- FIPS 204 and FIPS 205 cover ML-DSA and SLH-DSA signatures.
- NIST points implementers to its NCCoE migration project.
- Hybrid modes add margin but use more computing resources.
- 1.Inventory where cryptography is used and prioritize long-lived sensitive data.
- 2.Assess supplier readiness instead of treating migration as one update.
- 3.Use the NIST NCCoE project for visibility, priorities and demonstrations.

The National Institute of Standards and Technology (NIST) has released guidance on moving to post-quantum cryptography, giving federal agencies and technology providers a clearer path to quantum-resistant security. Published October 27, 2026, the finalized report identifies vulnerable cryptographic standards, their replacements, and the timelines that should shape migration plans.
