NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205)
NIST's Post-Quantum Cryptography (PQC) standardisation effort culminated in August 2024 with the publication of three Federal Information Processing Standards: FIPS 203 (ML-KEM, based on CRYSTALS-Kyber for key encapsulation), FIPS 204 (ML-DSA, based on CRYSTALS-Dilithium for digital signatures), and FIPS 205 (SLH-DSA, based on SPHINCS+ for hash-based digital signatures). These standards are designed to resist attacks from both classical and quantum computers.
