NSA Quantum-Resistant (QR) Cryptography Migration Guidance

The NSA has published multiple guidance documents for quantum-resistant cryptography migration beyond CNSA 2.0: 'Announcing the Commercial National Security Algorithm Suite 2.0' (2022), 'Quantum Computing and Post-Quantum Cryptography FAQ', and cybersecurity advisories on PQC transition. The guidance addresses: cryptographic agility (ability to quickly switch algorithms), risk assessment for quantum threats, prioritisation of migration activities, testing and validation of PQC implementations, supply chain considerations for PQC hardware, and coordination with allies through Five Eyes partnerships.
