Youssef El Housni

Cryptography engineer at ConsenSys and PhD Student at Ecole Polytechnique (Paris)

About

I am a cryptogrpahy engineer at ConsenSys (zkTeam) and a PhD student at Ecole Polytechnique (INRIA project-team GRACE) under the supervision of Prof. Daniel Augot and Prof. François Morain.

My work at ConsenSys consists in developing zero-knowledge cryptography libraires (see goff, gurvy and gnark) and my PhD research focuses on pairing-based zero-knowledge proofs and friendly related cryptographic primitives.

Interests

Zero-knowledge proofs
elliptic curves cryptography
pairing-based cryptography
privacy in blockchains
