Post-quantum cryptography (PQC) migration workshop report
As the NCSC has explained, in the future, a sufficiently powerful quantum computer will be able to break the public key cryptography that protects our networks and systems today. The mitigation to this threat is to migrate these systems to use PQC algorithms, which are based on mathematical problems that are not vulnerable to attack by quantum or classical computers.
The NCSC has set out key milestones for migration to PQC, which are intended to drive immediate action. While future targets appear distant, 2028 and 2031 will come around quickly, and organisations need to act now to stay ahead. This is because migration to PQC is not just a technical challenge; it’s a global strategic resilience imperative across industries and governments.
