NIST finalizes post-quantum cryptography migration guidance in NISTIR 8547
Original title: NIST Releases New Guidelines to Protect Encryption Against Future Quantum Computer Attacks
US high-value systems must move key establishment by 2030 and digital signatures by 2031; the broader federal target is 2035.
NIST published NISTIR 8547 on October 27, 2026, a framework for replacing cryptography vulnerable to future quantum computers. It names vulnerable standards and quantum-resistant replacements and builds on NIST’s August 2024 post-quantum standards, including FIPS 203 for key establishment. National Security Memorandum 10 sets 2035 for completing federal migration. Executive Order 14412 requires key establishment on federal high-value and high-impact systems by 2030 and digital signatures by 2031. Those dates are not universal private-sector deadlines.
Unconfirmed: The guidance does not say when cryptographically relevant quantum computers will exist.
- NIST cites harvest-now-decrypt-later collection of encrypted data for later decryption.
- The report allows hybrid conventional and post-quantum mechanisms, with higher compute cost.
- Migration covers products, services and the cryptographic supply chain, not only internal systems.
- NIST’s National Cybersecurity Center of Excellence is pairing the report with implementation demonstrations.
- 1.Prioritize post-quantum key management for data that must stay confidential long term.
- 2.Inventory vulnerable algorithms in code, configuration and certificates before migration.

The National Institute of Standards and Technology (NIST) has released finalized guidance to assist organizations in replacing cryptography that is vulnerable to quantum computing before future quantum computers pose a threat to sensitive information. Published on October 27, 2026, the report establishes a framework for migration that includes cryptographic standards, federal deadlines, and implementation priorities.
