Post-quantum migration guides

Use this page when you need the programme guide, not another summary of it.

This book does not replace these works. Each line is the job this edition is willing to repeat. Follow the link for the rest.

  • UK NCSC timelines, modified 3 August 2026. Three dates, who they are for, and the warning that much of the work for commodity IT arrives as a software update.
  • NIST IR 8547, October 2026. The US standards clock.
  • CISA, NSA, and NIST fact sheet, as of 17 August 2023. A short official start: inventory, vendors, and supply chain.
  • NCCoE migration FAQ, October 2026. Start with an inventory, then four guides.
  • Dutch PQC Migration Handbook (AIVD, CWI, and TNO, December 2024). Diagnose, plan, and execute, and sort urgent adopters, regular adopters, and cryptography suppliers. It is the strategy. This site does not rewrite it.
  • Dutch government resource list. Use the Dutch handbook for strategy and the PQCC roadmap as a supplement.
  • PQCC migration roadmap, May 2025. Four categories: preparation, baseline understanding, planning and execution, and monitoring and evaluation.
  • ETSI TR 103 619. Three stages: inventory, plan, execute. The migration is of public-key protections. It sets quantum key distribution and quantum random-number generators aside.
  • ETSI TR 104 016, October 2024. Eleven steps, repeated each year, for a programme office. It is not the front door of this site.
  • Canadian CFDIR quantum-readiness guide, July 2024. Actions a leadership team can take without a cryptographer. Canada's government milestone years are not restated here.
  • NIST SP 1800-38 volumes A (April 2023), B (December 2023), and C (December 2023) are still preliminary drafts. They are how to run cryptographic discovery, not a finished standard. Volume A, Volume B, Volume C.
