What is CNSA 2.0?

Also known as Commercial National Security Algorithm Suite 2.0.

NSA mandate to transition US National Security Systems to post-quantum algorithms. ML-KEM-1024, ML-DSA-87, SLH-DSA-256 are the CNSA 2.0 algorithm set. Compliance dates: 2030-2033 depending on system class. QNSI Government tier locks exactly to this algorithm set.

NSA CNSA 2.0 advisory

Decision context

Why CNSA 2.0 matters

CNSA 2.0 defines a transition suite and timelines for United States National Security Systems. It is highly relevant to that scope and to suppliers serving it, but it should not be presented as a universal certification or as evidence that every listed algorithm executes in a product.

How to evaluate CNSA 2.0

Map the system class and applicable transition milestone to the authoritative NSA guidance. Verify the exact required parameter sets, protocol profiles and implementation approvals. Keep readiness, configured policy, executed cryptography and accredited deployment status as separate evidence states.

Standards & programs

Standards & programs evidence boundary

Standards define algorithms, testing methods, transition expectations, or regulatory obligations; they do not automatically certify a product or deployment. Confirm the exact publication, version, scope, implementation evidence, and accountable assessment route before describing a system as compliant or validated.
