CNSA 2.0

NSA's Commercial National Security Algorithm Suite 2.0 — the mandate that moves US national security systems to post-quantum algorithms by 2033.

Core Principles & Analysis

• Mandates the highest parameter sets only — ML-KEM-1024 and ML-DSA-87, no smaller options.
• Firmware signing moves first via stateful hash-based LMS and XMSS, ahead of the lattice schemes.
• Sets 2025–2030 phase-in windows by system type, with full compliance required by 2033.

Specifications & Metrics

• PLATFORM: US national security systems
• MECHANISM: ML-KEM-1024, ML-DSA, LMS/XMSS, AES-256, SHA-384
• SINCE: 2022
