A definitive technical walkthrough of the steps, milestones, and testing requirements necessary to achieve formal NIST Cryptographic Module Validation Program accreditation for FIPS 203 ML-KEM implementations.
FIPS 140-3 harmonizes NIST requirements with ISO/IEC 19790 and ISO/IEC 24759. When applied to lattice-based cryptography, evaluators scrutinize polynomial arithmetic implementations for timing invariance, side-channel power signatures, and the integrity of discrete Gaussian or centered binomial noise generation.
Working with accredited National Voluntary Laboratory Accreditation Program (NVLAP) test houses requires standardized test interfaces. Modules must expose dedicated cryptographic boundary ports running ACVP client protocols, allowing test engines to inject random seeds, verify public key compression, and confirm that decapsulation failures trigger implicit rejection.
Achieving CMVP validation is not a one-time event. When upstream standards refine parameters or patch microarchitectural leakage paths, modules must maintain cryptographic agility. We detail re-validation thresholds, delta submissions, and continuous compliance monitoring strategies.
