Post-quantum deadlines for federal agencies, 2026 to 2035
Read the steps as text
- October 22, 2026. Agency PQC migration plans were due to OMB and the Office of the National Cyber Director, 120 days after M-26-15.
- October 27, 2026. NIST published the final IR 8547. M-26-15 requires migration plans to align with it.
- November 17 and 19, 2026. Comments close on two FedRAMP requests for comment: RFC-0035 (cryptographic module rules) and RFC-0036 (Class D pilot rules).
- December 19, 2026. 180 days after EO 14412: NIST must speed up cryptographic module validation, and the Federal Acquisition Regulation (FAR) Council must propose a contractor rule.
- January 2, 2030. Agencies must support Transport Layer Security (TLS) 1.3 or a later version.
- December 31, 2030. High value assets and high impact systems must use PQC for key establishment. After 2030, quantum-vulnerable public-key algorithms are deprecated.
- December 31, 2031. High value assets and high impact systems must use PQC for digital signatures.
- After 2035. Quantum-vulnerable public-key algorithms are disallowed under NIST standards.
NIST's final post-quantum transition plan deprecates RSA and elliptic curve cryptography after 2030
· Federal governance
NIST published the final IR 8547 on October 27, 2026. Every quantum-vulnerable public-key algorithm is now deprecated after 2030 and disallowed after 2035, and agencies' high value assets and high impact systems must move sooner: 2030 for key establishment and 2031 for signatures.
