PQC Migration Handbook for Post-Quantum Cryptography

This guide provides organizations with detailed guidelines for migrating to post-quantum cryptography (PQC) to address the potential threats posed by quantum computers. It emphasizes the urgency for organizations to begin migration efforts, especially those handling sensitive data or developing long-lived systems. The handbook outlines a three-step approach: Quantum-Vulnerability Diagnosis, Planning, and Execution. The first step involves assessing current cryptographic vulnerabilities and conducting a risk assessment. The Planning phase focuses on forming a dedicated team and ensuring business processes are in place for a smooth transition. The Execution phase provides strategies for implementing PQC without introducing new vulnerabilities. Additionally, the handbook discusses the importance of cryptographic agility, enabling organizations to adapt to evolving cryptographic standards and vulnerabilities. It also highlights recent developments, including the publication of PQC standards by NIST, which supports organizations in initiating their migration processes.
