United States transition timeline

The post-quantum transition is now on a federal clock.

These dates are not speculative. They are published federal directives, acquisition requirements and standards-transition milestones.

The 2027–2031 operational deadlines are established by federal policy. NIST’s 2030 and 2035 algorithm milestones remain a published draft transition plan and are labeled accordingly below.

2026 → 2035

One transition. Seven dated milestones.

Every entry links to the government source behind it. Labels distinguish binding policy direction from NSA transition requirements and NIST’s still-draft algorithm schedule.

Federal directive NSA transition requirement Draft NIST transition plan
Federal directive

Executive Order 14412 is signed.

“Securing the Nation Against Advanced Cryptographic Attacks” puts the federal post-quantum migration on explicit dates and directs the creation of minimum CBOM guidance.

NSA transition requirement

CNSA 2.0 becomes the default for new NSS acquisitions.

All new acquisitions for National Security Systems are required to be CNSA 2.0 compliant unless an NSA-published exception applies.

Federal directive

Minimum CBOM elements are due for public guidance.

EO 14412 §5(d) gives CISA, working with NIST, 270 days from 22 June 2026 to publish guidance on the minimum elements of a Cryptographic Bill of Materials. The calendar result is approximately 19 March 2027.

Federal directive

The NIST PQC migration pilot reaches its completion deadline.

EO 14412 §4(c) directs NIST to complete a pilot testing post-quantum migration methods and automated discovery and inventory tools by the end of 2027.

Federal directive Draft NIST transition plan

Federal key-establishment migration reaches its target date.

High-value assets and high-impact federal systems are directed to use post-quantum key establishment by this date. EO 14412 also directs a proposed FAR rule with a no-later-than 2030 transition date for covered contractors. Separately, draft NIST IR 8547 proposes deprecating 112-bit-strength RSA/ECC signatures and key-establishment schemes after 2030.

Federal directive

Federal digital-signature migration reaches its target date.

EO 14412 §4(b) directs high-value assets and high-impact federal systems to use post-quantum digital signatures by the end of 2031.

NSA transition target Draft NIST transition plan

Quantum-resistant NSS and the proposed end of quantum-vulnerable RSA/ECC.

NSM-10 set a 2035 national objective for mitigating quantum risk, and NSA’s CNSA 2.0 schedule targets all NSS as quantum-resistant by 2035. Draft NIST IR 8547 proposes disallowing quantum-vulnerable RSA/ECC and other public-key algorithms after 2035.

The inventory layer

You cannot migrate cryptography you cannot see.

A Cryptographic Bill of Materials is a structured, machine-assessable inventory of cryptographic assets: algorithms, key sizes, hash functions, protocol versions, implementations and libraries. It gives security teams a map of what must be evaluated, replaced or retired.

An SBOM inventories software components. A CBOM inventories the cryptography within and across those systems. EO 14412 explicitly brings CBOM into federal policy and directs CISA and NIST to define its minimum elements.
