I am excited to say that myself and my coauthors Benedikt Bünz and Kevin Choi have recently released a new paper: Golden, Lightweight Non-Interactive Distributed Key Generation.

I'm happy to say that I've recently published the paper "On the Adaptive Security of FROST," in collaboration with my co-authors Elizabeth Crites, Jonathan Katz, Stefano Tessaro, and Chenzhi Zhu.

I am happy to say that I've recently published the paper "On the Adaptive Security of Key-Unique Threshold Signatures," in collaboration with my (fantastic) co-authors Elizabeth Crites and Mary Maller.

Idealized models are a useful tool for proving the security of cryptographic schemes.

A few months ago, I wrote a short (informal) note that reviews the general forking lemma and several variations thereof, and discusses the differences among each variant.

First introduced by Pointcheval and Stern, the forking lemma is commonly used in proofs of security to demonstrate a reduction to breaking some known-to-be-hard mathematical problem.

I recently wrote a guest blog post for the Ethereum Foundation comparing security assumptions underpinning four threshold signature schemes, including FROST.

Schnorr signatures and identification protocols have undergone significant security analysis over the years.

I recently gave my first in-person lecture in almost two years since the pandemic began, and it was such a great experience.

I was invited to present FROST and to give recommendations for the standardization of Schnorr threshold signatures at the recent NIST workshop on standardization of threshold schemes!

I am excited to say that the camera ready version of our publication "Mind the Gap: Ceremonies for Applied Secret Sharing" in the Privacy Enhancing Symposium 2020 is out!
