THE G7 is pressing governments and organisations to accelerate the transition to quantum-safe security, ahead of the realisable threat from quantum computing to widely used public-key cryptography. Under France’s 2026 G7 Presidency, ANSSI chairs the G7 Cybersecurity Working Group and has published a call to action urging the public and private sectors to reframe the quantum threat as near-term and to begin PQC (post-quantum cryptography) migration across all sectors, not just critical infrastructure.
The document emphasises proactive action even before quantum computers capable of breaking current algorithms become available, and recommends prioritising systems with the most sensitive data and assets.
It sets out a phased, risk-based approach: organisations should inventory cryptographic assets, map dependencies, and develop a transition plan with a roadmap for implementing PQC as part of standard renewal cycles. To control transition costs, it suggests selecting products already integrating PQC and upgrading systems as they renew.
The plan also highlights five government and industry priorities: raising awareness of quantum threats; developing national PQC strategies with a reliable PQC hardware and software supply; directing R&D to practical PQC solutions; fostering public–private partnerships to build domestic quantum-safe expertise; and embedding PQC requirements into cybersecurity procurement and policy. The call was signed by the national cybersecurity agencies of all G7 members and is supported by the EU Commission and ENISA.
It follows ANSSI’s indication that post-quantum security will become mandatory in procurement by 2030, with some mandatory PQC features taking effect from 2027.
