NIST PQC Standardization
What is NIST PQC Standardization?
NIST PQC StandardizationThe multi-year NIST process that selects and standardizes post-quantum cryptographic algorithms; its first three standards, FIPS 203, 204, and 205, were published in August 2024.
The NIST Post-Quantum Cryptography (PQC) Standardization Project began in 2016 to identify replacements for RSA, Diffie-Hellman, and ECDSA that resist attacks by large-scale quantum computers. After four evaluation rounds across more than 80 candidate submissions, NIST published three final standards in August 2024: FIPS 203 (ML-KEM, based on CRYSTALS-Kyber) for key encapsulation, FIPS 204 (ML-DSA, based on CRYSTALS-Dilithium) and FIPS 205 (SLH-DSA, based on SPHINCS+) for digital signatures. FIPS 206 (FN-DSA, based on Falcon) and additional signature schemes from a parallel "on-ramp" call are in progress. The process now drives global PQC migration timelines in TLS, X.509 PKI, code signing, and government systems.
