France
EU roadmap Standard-contextualiserFrance's transition is led by ANSSI, the national cybersecurity authority, which treats post-quantum cryptography as the most promising defence against the quantum threat and now urges organisations across all sectors to migrate without delay. ANSSI sets out a phased approach in which standalone post-quantum deployments follow earlier hybrid phases, and in early 2026 it published concrete transition guidance for TLS 1.3, SSHv2 and IPsec alongside an updated cryptographic mechanisms guide that adds post-quantum signature and key-establishment rules. The posture is reinforced by binding national instruments, including the 2024 to 2030 military programming law, which names the move to post-quantum cryptography as a defence priority, and the France 2030 call for projects that funds a domestic post-quantum offer. The first security visas covering products with post-quantum cryptography have now been issued. In the financial sector the ACPR and the Banque de France are raising awareness and advancing a coordinated roadmap, and France aligns its timetable with the EU coordinated implementation roadmap.

Regulatory basis
- Law No. 2023-703 of 1 August 2023, military programming 2024-2030 (PQC transition named a defence technology priority)
- Order of 17 March 2022 approving the France 2030 'Cryptographie Post-Quantique' call for projects specifications
- ANSSI PQC migration position and roadmap (phased approach; alignment with the EU coordinated roadmap)
- ANSSI Common Criteria security visa with PQC requirements (first PQC security visas issued)
Legal status: Binding
Essential and important entities must use state-of-the-art cryptography under NIS2; products seeking ANSSI certification must meet its PQC requirements, including mandatory hybridisation, by the visa deadlines (2027 sensitive products, 2030 all certified products).
Standards and algorithms
No standards or algorithms specified.
