Post-Quantum Cryptography (PQC), sometimes referred to as quantum-safe cryptography, is cryptography that is resistant to attack by quantum computers. PQC algorithms use different kinds of mathematics from traditional cryptography but are designed to run on classical computers and existing networks.

For many use cases, upgrading to PQC is as simple as a software update. For others, the process is far more complex. Last year, the National Cyber Security Centre (NCSC) published migration timelines for PQC readiness, which advise high-priority migration to PQC by 2031. The process can be complex, and the guidance aims to give clarity on how to manage the cryptography ecosystem. Many international partners also follow a similar timeline.

In the blogs below, our members explore how to reduce early barriers to adoption, offer clarity for organisations preparing for PQC and review how industry and government can work together.
