Quantum computing is leaping from physics labs straight into national security policy. By 2030, analysts at security firm Project Eleven estimate that next-generation machines will pack enough processing power to crack the cryptographic keys securing modern digital infrastructure, putting roughly 7 million Bitcoin at direct risk. To intercept this threat, France’s national cybersecurity agency, ANSSI, announced it will officially stop certifying security products that rely on conventional encryption starting in 2027.
The policy forces organizations and critical infrastructure operators to exclusively purchase quantum-safe products by 2030. This creates a hard expiration date for older cryptographic systems across the country. ANSSI Chief of Staff Samih Souissi detailed the strict timeline at the France Quantum conference, telling attendees the transition is a matter of “governance, industrial planning, regulation, and sovereignty.”
The Mechanics of the Harvest Attack
The urgency behind the 2027 deadline centers around a specific exploit known as “harvest now, decrypt later.” Adversaries are currently intercepting and storing vast amounts of highly classified, encrypted data. They cannot read the information today, but they are hoarding the data packets until quantum computers mature enough to unlock the files.
Systems designed for long operational lifespans, such as virtual private networks (VPNs) and public key infrastructures, face the most immediate compliance pressure under these new rules. Recognizing the shrinking timeline, the global blockchain industry is accelerating its defense strategies. The Ethereum Foundation formed a dedicated post-quantum security team to audit its networks. Simultaneously, Coinbase’s quantum advisory council is instructing clients to begin migration planning, and the Stellar Development Foundation rolled out a three-stage roadmap to upgrade the XLM network.
Why ANSSI’s Deadline Accelerates NIST Adoption Across Europe
France’s 2027 certification cutoff ranks as the strictest government mandate on post-quantum cryptography adoption in Europe to date. The policy explicitly aligns French critical infrastructure procurement with the post-quantum guidelines established by the U.S. National Institute of Standards and Technology (NIST) in 2024, which prioritize advanced algorithms like ML-KEM and ML-DSA.
This alignment bans the future use of classical RSA and elliptic curve cryptography (ECC) in regulated networks. ECC currently forms the foundational security layer for major cryptocurrencies, banking apps, and digital wallets. As institutions race to replace their ECC frameworks to comply with the 2027 target, cybersecurity companies focused entirely on quantum-resistant software, such as CryptoNext Security, are preparing for a sharp increase in enterprise demand.
