UK's NCSC Sets Ambitious Post-Quantum Cryptography Migration Timeline to Fortify Cyber Resilience Against Quantum Threats

The UK's National Cyber Security Centre (NCSC) has issued guidance for transitioning to post-quantum cryptography (PQC). * Targeted at large organizations and critical infrastructure operators. * Aims to mitigate risks from quantum computers breaking current encryption. * Organizations should define goals and assess dependencies by 2028. * Early migration activities should start by 2031, with a refined roadmap in place. * Full migration to PQC is expected by 2035. * The approach aligns with global PQC efforts, including NIST standards (ML-KEM, ML-DSA, SLH-DSA, HQC). * Critical infrastructure and legacy systems may require extensive planning and investment. * NCSC plans a pilot scheme to assure consultancy firms offering migration support.
