FIPS 140-3 and the Quantum Imperative

FIPS 140-3 replaces FIPS 140-2 and aligns with ISO/IEC 19790 and ISO/IEC 24759, while quantum computers threaten RSA and ECC once large-scale systems become operational. This architecture insight traces the evolution from FIPS 140-1 to FIPS 140-3 and explains how CleanStart OS uses modular cryptographic boundaries to add post-quantum algorithms such as ML-KEM, ML-DSA and SLH-DSA without re-engineering the compliance architecture. It covers hybrid classical and post-quantum configurations, cryptographic agility and algorithm policy tied to FIPS 140-3 profiles.
