Verification is a public service, it is a good deed performed by companies who contribute very little good to the world in my opinion. We should be making easier clearer paths to verification for everyone, not making it harder. It is their responsibility, not a business model.

I don't tweet much anymore, but I halfheartedly moved to mastodon as everybody else: @[email protected] . If you'd like me to follow you.please post your handle below.

first cryptography paper online <3 we present a new, post-quantum secure OPRF (the asymmetric primitive behind OPAQUE, private set intersection and many more!). Also, we show a super-simple attack on another construction that only uses elementary school math-check it out!

Today Microsoft open-sourced MS-DOS 4.0. You can check it out here: github.com/microsoft/MS-D…

OPRFs are one of the most widely used privacy tools, but they’re under threat from developments in quantum chips. In this work we present Leap, a lattice-based OPRF using MPC tools (OT, OLE) for post-quantum security—fast eval (<1ms) & efficient PSI. Joint work with

Leap: New post-quantum oblivious pseudorandom function (OPRF). OPRF is a 2PC between a server which holds a secret key, and a client who provides input. The server learns neither the input nor the output. The client doesn’t learn the key.

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. cfl.re/42YD7Ua

We're sharing our new research on converting multiple key-dependent attacks into universal attacks. This work comes with open-source implementation tools and GPU-accelerated experiments to support reproducibility: Paper: ia.cr/2025/1996 github.com/hadipourh/univ…

Agents need credentials that protect the privacy of the users behind them. Read more about it blog.cloudflare.com/private-rate-l… Joint work with Lena Heimberger, Christopher Patton, and Thibault at Cloudflare

Working on anonymous credentials? In this blog post Christopher Patton and l.e.a. tells about the state of Post-Quantum credentials. blog.cloudflare.com/pq-anonymous-c…

Web servers need better tools to manage agentic traffic. Fortunately, we can build these tools in a way that protects the privacy of the human in the loop. blog.cloudflare.com/private-rate-l…

Anonymous credentials are going to have a big year. In the realm of "fancy" cryptography, they're perhaps the most important primitive we'll need to make PQ. Where do we stand? Lena Heimberger spent part of the summer finding out. blog.cloudflare.com/pq-anonymous-c…
