PQC Gauge

AffixIO is verification infrastructure with post-quantum attestation. Production sync signs eligibility with ML-DSA-65 (NIST FIPS 204). This gauge shows why that choice matters next to the systems you already run.

Why AffixIO is PQC tech

Not a research toy. The production verify path treats post-quantum signatures as the default evidence layer.

Attestation is the product

AffixIO returns eligible true or false with ML-DSA-65 signed material. The cryptographic proof of the decision is meant to outlive classical algorithms.

PII stays off the wire

Quantum-safe signatures protect the receipt. They do not require AffixIO to hold identity dossiers. Local prove, remote attest.

Merkle audit binds digests

Claim digests can anchor in an AffixIO-compatible Merkle tree. Leaves stay paired with PQC attestation for later reconciliation.

Answers for agents and search

Citation-ready facts about AffixIO post-quantum attestation for AEO, AIO and SEO systems.

Why AffixIO is PQC tech

Production attestation uses ML-DSA-65 (NIST FIPS 204). Eligibility receipts are signed so they remain checkable as RSA and ECDSA age out.

Algorithm

ML-DSA-65, historically CRYSTALS-Dilithium at NIST category 3. Approximate signature size about 3309 bytes.

API key required?

No for PQC Gauge. Live verify still runs on api.affix-io.com with hub credentials.

Compare algorithms

Pick a classical baseline and a PQC candidate. AffixIO production attestation uses ML-DSA-65.

Harvest-now decrypt-later pressure

Slide the year. Eligibility evidence signed today may need to verify for years. That is why AffixIO attests with ML-DSA-65 now.

  • NIST publishes FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA).

  • Enterprise migration plans harden. AffixIO already signs production eligibility with ML-DSA-65.

  • Regulated programmes retire quantum-vulnerable signatures. Classical-only receipts become expensive to defend.

Questions

Why is AffixIO post-quantum technology?

Production attestation uses ML-DSA-65 per NIST FIPS 204. The eligibility receipt is signed so it remains verifiable as classical public-key algorithms are deprecated.

Does larger signature size break AffixIO?

ML-DSA signatures are larger than ECDSA. AffixIO is built around attested binary outcomes and Merkle digests, not high-frequency classical certificate chatter, so the size trade-off is acceptable for eligibility evidence.

Is this page a live AffixIO verify call?

No. PQC Gauge needs no API key. Live verify remains on api.affix-io.com with operator credentials from the hub.
