# Post-quantum algorithm crosswalk

One row per algorithm. Each row gives its family, its status (post-quantum, quantum-vulnerable, classically weak or approved), the
governing NIST standard and its role under NSA CNSA 2.0. It's meant for CBOM tooling and migration inventories.

Milestones: new National Security System acquisitions must be CNSA 2.0 compliant from 1 January 2027. Software and
firmware signing must be exclusively CNSA 2.0 by 2030, using LMS/XMSS rather than ML-DSA for firmware.

This is SSX360's summary. Check the NIST and NSA publications before relying on it.
