Cloudflare cuts aggressive path to PQC with Kyber beta rollout

Cloudflare, a content delivery network and security company, has adopted the recently-chosen Kyber standard for public key encryption as the post-quantum cryptography (PQC) solution for providing transport layer security to all of its website and API customers. 

The launch of the beta program comes well ahead of the finalization of the Kyber standard.

It is an announcement of massive significance for multiple reasons:

Though it is a bold move, it should hardly come as a surprise, as Cloudflare has been working on PQC efforts itself for years. It has been closely following the NIST standardization proceedings, and has published several in-depth blog posts on the topic in recent months.

The company emphasized in its blog post that the beta program will help the Internet community better understand Kyber and what it is getting into as it embarks on the PQC migration. “The transition to a post-quantum secure Internet is urgent, but not without challenges,” the post stated. “Today we have deployed a preliminary post-quantum key agreement on all our servers — a sizable portion of the Internet — so that we can all start testing the big migration today. We hope that come 2024, when NIST puts a bow on Kyber, we will all have laid the groundwork for a smooth transition to a Post-Quantum Internet.”

The PQC migration is expected to be the big topic of conversation and debate later this month at the IQT Fall Quantum Cybersecurity event in New York City.
