Representatives from the G7 nations signed a treaty in Evian, France, establishing the first global standards for quantum-resistant cryptography. The agreement sets a firm deadline of 2030 to upgrade encryption across military communications, financial networks, and electrical grids.
The move comes as quantum processors near the scale required to break traditional RSA and ECC encryption. While stable decryption machines do not yet exist, security agencies warn that adversaries are actively harvesting encrypted data to decode later.
The Shift to Post-Quantum Encryption
The new standards rely on lattice-based cryptography, which uses complex multi-dimensional mathematical structures that classical and quantum computers struggle to solve. The US National Institute of Standards and Technology (NIST) provided the underlying algorithms for the treaty.
"We are preparing our security systems before the threat materializes," says French Digital Minister Jean-Noël Barrot. "A late migration would leave our entire banking infrastructure vulnerable."
The treaty includes $45 billion in joint funding to assist developing nations in updating their public communication systems.
