## CISA and G7 urge a shift to post-quantum cryptography

According to CISA (the U.S. Cybersecurity and Infrastructure Security Agency) and the G7 Cyber Security Working Group, organizations should begin moving to post-quantum cryptography (PQC) now. In a joint call to action published on 3 September 2026, the partners warn that advances in quantum computing pose a real threat to public-key encryption, the technology that protects TLS, VPNs, digital signatures and smart cards. Partners shown in the announcement include France's ANSSI, Germany's BSI and the United Kingdom's NCSC, alongside the European Commission and ENISA (the EU cybersecurity agency).

According to the joint document, the exact timeline is uncertain, but several recent advances suggest the coming of quantum computers able to break widely used public-key encryption. The document describes post-quantum cryptography (PQC) as a new field of cryptography designed to resist both classical and quantum attacks, and says that for this reason organizations should begin their transition as soon as possible, both to avoid quantum risk and to provide long-term protection of confidential data.

## Harvest now, decrypt later

The urgency does not come from quantum computers breaking encryption today. According to the call, the real risk is what analysts describe as "harvest now, decrypt later" (also known as store now, decrypt later). An adversary copies and stores data protected by public-key encryption now, then decrypts that archive retroactively once a sufficiently powerful quantum computer exists. This means information whose secrecy must last for years, such as state secrets, health and biometric records, intellectual property and long-term contracts, is already exposed today, even if a capable quantum machine is still years away. That is why, CISA and the G7 group say, the inventory work has to start now: the transition takes years, while the data can be collected already.

## What the call asks organizations to do

According to CISA's message, organizations should take four concrete steps:

- **Inventory** their cryptographic assets.
- **Map** their dependencies.
- **Develop** phased transition plans.
- **Integrate** PQC into procurement processes.

The G7 Cyber Security Working Group also lists five priorities for a successful PQC transition:

- Raising awareness of quantum risks and the importance of PQC.
- Developing national strategies that support PQC adoption and integration.
- Advancing research into quantum-resistant technologies.
- Encouraging public-private partnerships for sharing expertise and resources.
- Building PQC into cybersecurity requirements and procurement.

## Why it matters beyond the G7

Turkey is not a party to this U.S. and G7 document. Even so, the threat is global and the infrastructure is shared: the public-key encryption behind TLS, VPNs, digital signatures, smart cards and e-signatures works the same everywhere. For public bodies and financial institutions that hold long-lived data, the same steps, inventory, map, plan and integrate into procurement, apply just as well.
