PQC in Plaintext: Google Cloud’s post-quantum cryptography roadmap
TL;DR
Google Cloud is advancing its post-quantum cryptography (PQC) strategy, aiming for full implementation by 2029 to secure services against future quantum threats.
✦ Why It Matters
Evaluate your current cryptographic practices and consider transitioning to post-quantum solutions to future-proof your systems.
Key Takeaways
- Implement quantum-safe key exchanges in your applications.
- Transition to quantum-resistant digital signatures by 2028.
- Use Cloud Asset Inventory to map cryptographic resources.
- Update software to support PQC algorithms like BoringSSL.
Full Summary
For over a decade, Google has focused on securing its infrastructure against potential quantum computing threats. The updated roadmap outlines a strategy to transition to post-quantum cryptography (PQC) by 2029, emphasizing three main areas: mitigating risks of data being stored now and decrypted later, ensuring the integrity of digital signatures, and enhancing cryptographic agility.
Immediate milestones include implementing quantum-safe key exchanges in Google Cloud API endpoints and load balancers, as well as deploying NIST-standardized PQC algorithms. By 2026, Google aims to provide quantum-safe solutions across its services, with a focus on protecting customer workloads and securing data pipelines.
The roadmap also includes plans for transitioning public key infrastructure to support quantum-resistant certificates by 2028, ensuring that Google Cloud remains at the forefront of quantum readiness.
