Commercial National Security Algorithm Suite (CNSA) 2.0
What is Commercial National Security Algorithm Suite (CNSA) 2.0?
The Commercial National Security Algorithm Suite (CNSA) 2.0, announced by the NSA in September 2022, defines a set of cryptographic algorithms-including AES‑256, SHA‑384, ECDSA P‑384, RSA‑3072, CRYSTALS‑Kyber (KEM) and CRYSTALS‑Dilithium (signature)-required for National Security Systems (NSS). CNSA 2.0 supersedes CNSA 1.0 and establishes a transition schedule: new NSS must adopt CNSA 2.0 algorithms by 2030, with full migration required by 2035.. It comprises 14 controls organised across 3 domains, and applies in the United States (National Security Agency).
How Commercial National Security Algorithm Suite (CNSA) 2.0 maps to other frameworks
All 14 controls, each one mapped to the equivalent requirement in other standards, with the evidence that carries across and the mappings that were judged and rejected shown alongside. No account needed to look.
