Short introduction

Hi there! I am Léo Ackermann. Since October 2022, I am a PhD student in cryptography in the CAPSULE team at Inria/IRISA in Rennes and the AMACC team at GREYC in Caen, supervized by Adeline Roux-Langlois (CNRS) and Alexandre Wallet (Inria). I am working on lattice-based cryptography, and more precisely I am working on the Module Learning With Errors problem from both theoritical (settling the hardness of the problem) and pratical (designing efficient post-quantum secure primitives from this problem) point of view.

In August 2022, I graduated from the École Normale Supérieure de Rennes and the MPRI (MRes) with honors. Before that, I was an intern supervized by Adeline Roux-Langlois and Alexandre Wallet, working on reductions from lattice hard problems to the Learning With Errors computational problem.

Formely, I worked (at an intern) with Myrto Arapinis and Nikolaos Lamprou at the university of Edinburgh. We focused on improving E-cclesia, a blockchain-based universally composable self-tallying election scheme in Canetti's universally composable model. I also did a research project supervized by Adeline Roux-Langlois, on an electronic voting scheme relying on lattice-based blind signatures.

As you guessed, I am mainly interested in cryptography and the security of protocols, while staying really curious about quantum computer science, distributed algorithms or even logics.
