NIST IR 8547 sets federal post-quantum deadlines for 2030 and 2031
October 29: Cyber Security News names the mapped algorithms as FIPS 203 ML-KEM, FIPS 204 ML-DSA and FIPS 205 SLH-DSA, says no new algorithm was added, and notes federal suppliers should assess customer requirements.
NIST’s October 27 roadmap requires prioritized federal systems to adopt post-quantum key establishment by 2030 and signatures by 2031, with a 2035 federal target.
NIST published Transition to Post-Quantum Cryptography Standards (NIST IR 8547, also NISTIR 8547) on October 27, 2026, mapping quantum-vulnerable public-key cryptography to existing 2024 standards rather than adding a new algorithm: FIPS 203 ML-KEM, FIPS 204 ML-DSA and FIPS 205 SLH-DSA. It prioritizes FIPS 203 where data must stay secret for a long time and allows hybrid conventional-plus-PQC protection. Under Executive Order 14412, high-value, high-impact and other prioritized federal systems must use quantum-resistant key establishment by December 31, 2030, and digital signatures by December 31, 2031. National Security Memorandum 10 keeps 2035 as the broader federal completion target. NIST will deprecate vulnerable public-key methods after 2030 and disallow them under its standards after 2035; the dates are not universal private-sector deadlines, though federal suppliers are told to assess customer requirements.
- NIST IR 8547 was published on October 27, 2026.
- Key-establishment deadline is December 31, 2030; signatures, December 31, 2031.
- Mapped standards are FIPS 203 ML-KEM, FIPS 204 ML-DSA and FIPS 205 SLH-DSA.
- Agencies must support TLS 1.3 by January 2, 2030, according to Help Net Security.
- Vulnerable public-key methods are deprecated after 2030 and disallowed after 2035.
- Executive Order 14412 was published in June 2026.
