Transition to Post-Quantum Cryptography Standards

What Transition to Post-Quantum Cryptography Standards requires

This report describes NIST’s expected approach to transitioning from quantum-vulnerable cryptographic algorithms to post-quantum digital signature algorithms and key-establishment schemes. It identifies existing quantum-vulnerable cryptographic standards and the quantum-resistant standards to which information technology products and services will need to transition. This guidance is intended for a broad audience, including federal agencies, technology providers, standards organizations, and Cryptographic Module Validation Program (CMVP) laboratories, to inform their efforts and timelines for migrating information technology products, services, and infrastructure to Post-Quantum Cryptography (PQC). The core obligation is to transition cryptographic systems to quantum-resistant cryptography, with a primary target for completion across Federal systems by 2035, as established by National Security Memorandum 10 (NSM-10). There is a pressing threat, known as “harvest now, decrypt later,” where adversaries collect encrypted data now with the goal of decrypting it once quantum technology matures. This threat makes the transition urgent, particularly for sensitive data that retains its value for many years. The transition will involve the adoption of new PQC algorithms like those in FIPS 203, 204, and 205, as well as the careful deprecation, controlled legacy use, and eventual removal of quantum-vulnerable algorithms.
