NIST is advancing nine new post-quantum signature algorithms as potential candidates for future standardization. We look at all of them, and argue that while they are in the works and show great potential, we should use ML-DSA for now — the best one currently available.
The world is adopting anonymous credentials for digital privacy, but these systems are vulnerable to quantum computers. This post explores the cryptographic challenges and promising research paths toward building new, quantum-resistant credentials from the ground up.
As AI agents change how the Internet is used, they create a challenge for security. We explore how Anonymous Credentials can rate limit agent traffic and block abuse without tracking users or compromising their privacy.
Cloudflare is launching an experiment with Chrome to evaluate fast, scalable, and quantum-ready Merkle Tree Certificates, all without degrading performance or changing WebPKI trust relationships.
This post is a beginner's guide to lattices, the math at the heart of the transition to post-quantum (PQ) cryptography. It explains how to do lattice-based encryption and authentication from scratch.
It's hard to tell the difference between web content produced by humans and web content produced by AI. We're taking new approach to making AI content distinguishable without impacting performance.
Cloudflare announces Post-Quantum Cryptography as a Generally Available system
Cloudflare is implementing DAP (Distributed Aggregation Protocol) – a way of aggregating data without exposing individual measurements that uses multi-party computation
The future is post quantum. Enable post-quantum key agreement on your test zone today and get a headstart
In this post, we’ll dig into ECH details and describe what this protocol does to move the needle to help build a better Internet.
A deep dive into the Encrypted Client Hello, a standard that encrypts privacy-sensitive parameters sent by the client, as part of the TLS handshake.
When you visit a secure website, it offers you a TLS certificate that asserts its identity. Every certificate has an expiration date, and when it’s passed due, it is no longer valid.
