Quantum-Readiness: Migration to Post-Quantum Cryptography

This factsheet was created by CISA, NSA, and NIST to inform organizations, especially those that support critical infrastructure, about the impacts of quantum capabilities. Quantum-Readiness: Migration to Post-Quantum Cryptography (PQC) includes recommendations to establish a Quantum-Readiness Roadmap, steps to prepare a useful cryptographic inventory, considerations for understanding and assessing supply chain, how organizations should engage with their technology vendors to discuss PQC, and responsibilities of technology vendors.
