NSA CNSA Suite 2.0 — Commercial National Security Algorithm Suite
The NSA's Commercial National Security Algorithm Suite 2.0 (CNSA 2.0), announced September 2022, establishes the quantum-resistant cryptographic algorithms required for National Security Systems (NSS). CNSA 2.0 replaces CNSA 1.0 and mandates transition to post-quantum algorithms. Timeline: software/firmware signing (2025), web browsers/servers and cloud services (2025), traditional networking equipment (2026), operating systems (2027), niche equipment (2030), legacy equipment retirement (2033). Key algorithms: CRYSTALS-Kyber (ML-KEM), CRYSTALS-Dilithium (ML-DSA), XMSS/LMS (stateful hash-based signatures), SHA-384/512, and AES-256.
