Post-Quantum Attestation in Production with ML-DSA-65 is an AffixIO technical paper. Sign audit roots today so quantum cannot rewrite them tomorrow.

Store-now-decrypt-later makes classical signatures a liability for records kept ten years. AffixIO signs Merkle roots with ML-DSA-65 inside FIPS 140-2 Level 3 HSMs. This paper is the production guide we wished existed when we migrated.

Frequently asked questions

Why ML-DSA-65 specifically?

It is NIST's module-lattice standard with conservative parameter sets suited to long-lived governance records.

When does quantum break RSA for archives?

Nobody knows the exact date, but captured signatures are already at risk under harvest-now-decrypt-later.

Where are keys stored?

a certified HSM in eu-west-2 with private keys non-exportable from hardware.
