Quantum Threat: France Mandates Quantum-Safe Encryption by 2027

France is taking a significant step to prepare for the quantum computing era. ANSSI, the nation's cybersecurity agency, announced that from 2027, security products will no longer be certified without quantum-resistant encryption. By 2030, businesses are advised to exclusively purchase quantum-safe products. This policy will effectively phase out older, vulnerable systems, particularly those critical for government and infrastructure.

Experts stress the critical need for this transition, warning that delaying the implementation of post-quantum encryption carries severe risks. The potential for quantum computers to "unscramble" current encryption, which safeguards everything from financial transactions to government communications, is a growing concern. This threat, often termed "Q-day," necessitates proactive measures now.

Industry leaders are responding to the call for quantum preparedness. OVHcloud highlighted the dual compliance burden for auditing products and securing data. IBM Quantum estimates quantum threats could emerge by the mid-2030s. Companies like Qperfect noted that blockchain standards could be among the first systems compromised. However, implementing new schemes presents challenges, including potential trade-offs in performance and size.
