Brief Biography

I am the head of cryptography at Coinbase and a professor in the Department of Computer Science at Bar Ilan University (on leave). I received my Ph.D. in 2002 from the Weizmann Institute of Science, under the supervision of Oded Goldreich and Moni Naor, and was a Raviv Postdoctoral fellow in the Cryptographic Research Group at the IBM T.J.Watson Research Center in 2002-2004.

I was the co-founder of a company called Unbound Security that used secure multiparty computation to protect cryptographic keys and secrets of all types. In January 2022, Unbound Security was acquired by Coinbase.

Research Interests

My main research interests are in the field of cryptography, with a focus on secure multiparty computation (MPC).
My research concentrates both on questions of feasibility and efficiency, as well as practical implementations. Research on feasibility asks what cryptographic tasks can be realized and under what assumptions, and is related to the theoretical foundations of cryptography. Research on efficiency focus on the construction of efficient cryptographic schemes and protocols that have rigorous proofs of security and correctness. Today, MPC has transitioned from a theoretical notion to a tool that is used commercially. My research on practical implementations studies the use of MPC (and cryptography in general) to solve current business needs.
