Quantum computers will break the cryptography that protects most of the world's data. The only question is when.
The National Security Agency has already set the timeline. CNSA 2.0 mandates that new National Security Systems must support post-quantum algorithms by January 1, 2027. That is less than four months away.
The migration is not theoretical. It is a procurement deadline with legal force.
What CNSA 2.0 Requires
The Commercial National Security Algorithm Suite 2.0 replaces RSA, ECDSA, and Diffie-Hellman with post-quantum algorithms.
| Requirement | What It Means |
|---|---|
| Software and firmware signing | All signed code must use CNSA 2.0 algorithms |
| Operating system migrations | Legacy OS deployments must be updated |
| Procurement gate | Any new system purchased after January 1, 2027 must support CNSA 2.0 upon delivery |
The directive is explicit. Organizations that cannot demonstrate compliance will be excluded from the National Security Systems supply chain.
The Problem
Most organizations cannot prove their migration happened correctly.
They can show a policy document. They can show a project plan. They can show a vendor's assurance letter.
They cannot show a deterministic, replayable record of every cryptographic decision made during the transition. Which algorithms were replaced. When. By whom. Against which standard. With what result.
The deadline requires proof. Not promises.
What the Record Looks Like
A compliant cryptographic transition record contains:
- The specific system or component being migrated
- The legacy algorithm being replaced
- The post-quantum algorithm being deployed
- The compliance framework being satisfied
- The date and time of the decision
- The rationale for the chosen replacement
- A cryptographic hash chaining the record to the previous one
When an auditor asks "prove this system was migrated before the deadline," the record is the answer.
Why Determinism Matters
Quantum migration is binary. A system either supports post-quantum algorithms or it does not. A migration either happened or it did not.
The record of that migration must be equally binary. Same input. Same output. Replayable. Verifiable. Tamper-evident.
Probabilistic logs cannot prove a migration. Screenshots cannot prove a migration. A vendor's word cannot prove a migration.
Only a deterministic audit trail can.
The Deadline
January 1, 2027. Less than four months.
Organizations that have not begun will scramble. Those that have begun will need proof. Those with no proof will be excluded.
The mandate is set. The clock is running. The record is the requirement.
