France sets 2027 quantum encryption test as crypto watches

France’s cybersecurity agency ANSSI will stop certifying security products that lack quantum-resistant encryption starting in 2027. The rule applies to products sold to French government bodies and critical infrastructure operators, where ANSSI approval often determines whether a system can be deployed at all.

ANSSI Chief of Staff Samih Souissi said businesses should buy only quantum-safe products by 2030. “It’s not only a technical issue,” he said. “It’s a matter of governance, industrial planning, regulation, and sovereignty.” The statement turns a long-running industry warning into a concrete procurement test.

France lines up with the U.S. National Security Agency’s CNSA 2.0 timeline. Under that program, new U.S. national security system acquisitions must support approved quantum-resistant algorithms from Jan. 1, 2027. Systems unable to run the new suite must be phased out by the end of 2030.

The shared date matters for vendors selling into defense, government, banking and critical infrastructure markets. A product without post-quantum cryptography may soon lose access to major public contracts. The shift gives suppliers less room to treat quantum readiness as a future upgrade or a marketing label. It also sets a clear date for budgets, audits and product roadmaps.

The crypto industry relies on cryptography to protect wallets and validators. No active quantum attack targets current blockchains. Researchers and companies warn that upgrade work can take years. That makes advance planning part of the security process rather than a last-minute patch.

Bitcoin remains a central concern. Some older or reused addresses expose public keys. Coinbase’s advisory board has urged Bitcoin developers to start building a migration path toward post-quantum cryptography. The debate is difficult because any forced migration could affect inactive wallets and coins believed lost. A slow migration could also leave users unsure which wallets remain safe.

Some networks have already mapped early steps. Coinbase has singled out Algorand and Aptos as better positioned for a post-quantum transition than many rivals. It also warned that proof-of-stake chains like Ethereum and Solana may need extra work because validator signatures help secure the networks.

Ethereum and Solana have both discussed paths toward quantum-resistant signatures. Algorand has tested quantum-resistant tools. Aptos has an account design that could ease upgrades. These steps do not remove the threat. They show that major networks are treating post-quantum security as part of long-term planning.

France’s decision adds regulatory pressure to a technical race. Vendors must now show how products can survive future quantum threats. Crypto teams must explain how wallets, validators and users can migrate safely. The 2027 and 2030 deadlines now sit on procurement calendars and blockchain roadmaps alike.
