The UK's National Cyber Security Centre (NCSC) announced a decade-long timeline for organizations to migrate to post-quantum cryptography (PQC) to counteract threats posed by future quantum computers. Key milestones indicate that by 2028, organizations should have defined their migration goals and systems for upgrade. By 2031, priority migrations must be completed, with a clear pathway outlined. Full migration to PQC should be achieved by 2035, ensuring robust cybersecurity against evolving threats. The NCSC anticipates that ten years suffices for developing necessary standards and widespread adoption, enabling significant improvements in encryption security.
Given that real-world quantum computers capable of practical use are still estimated to be decades away, the ten-year deadline would put UK organizations well ahead of the curve.
The NCSC believes that ten years is a sufficient period for a rich set of PQC standards to appear, for an ecosystem of products that uses them to be developed, and for uptake to become widespread.
