Using AI to chart a course for our post-quantum migration

As laboratories around the world race to build out a cryptographically relevant quantum computer, we at Cloudflare are racing towards a 2029 target deadline for full post-quantum readiness.

Key points

  • While we’ve already transitioned many of our products to post-quantum encryption, we still have work to do to support post-quantum authentication and achieve full post-quantum readiness across our platform.
  • We’re taking a maximalist stance (“PQ everything!”), because as an infrastructure provider to the world, we want to give our customers the peace of mind that using Cloudflare ensures that their traffic is future-proofed against quantum adversaries.
  • Many of our products have already been upgraded to post-quantum encryption over TLS 1.3, but we still want to cover the long tail of TLS connections, as well as upgrade any other uses of public-key encryption.
  • If our products or platform rely on protocols that don’t yet have a PQ migration plan (because PQ variants of the system have not yet been considered, because PQ standards do not exist or lack consensus, or because software libraries or other key ecosystem components do not yet have PQ support), then we need to know now.
