Guide to Post-Quantum Cryptography Transition

This guide provides a comprehensive framework for organizations to transition to post-quantum cryptography (PQC) in response to the emerging threats posed by quantum computing. It outlines the critical need for early planning and preparation, emphasizing that the migration to PQC is essential for maintaining security and compliance. The document details the current landscape of cryptographic standards, including the National Institute of Standards and Technology (NIST) PQC algorithms and the regulatory requirements set forth by various government bodies. It presents a timeline for migration, highlighting the urgency due to the predicted arrival of cryptographically relevant quantum computers (CRQCs) and the potential compression of the migration window to as little as three years. The guide also addresses common challenges organizations may face during the transition and provides practical tools and resources to facilitate the process. By understanding the quantum divide and the implications for existing cryptographic systems, organizations can better prepare for a secure future in the quantum era.
