About Me

I'm a recent Ph. D. graduate from Université de Montréal with a thesis on quantum cryptography. I'm currently employed as a machine learning software engineer at Irosoft.

Interests and Projects

During my Ph. D. studies, my research has been focused on finding tools for proving the security of quantum cryptographic protocols for two-party secure computation. In my thesis, I propose new, general proof techniques to facilitate the analysis of cryptographic protocols that rely on quantum mechanics. Here is a piece of my thesis's abstract that succinctly describes my contribution.

Quantum mechanics offers an undeniable advantage over classical mechanics for conceiving protocols for cryptographic tasks. However, it also allows for complex attacks that make quantum protocols hard to analyze and cryptographers are thus always looking for new tools to simplify proofs. In this thesis, we introduce new techniques that simplify the analysis of quantum cryptographic protocols and we showcase their usefulness with some applications. Our techniques are used to show that, under certain condition, the security of a protocol against an attacker that more or less follows the honest behaviour (passive) is a sufficient condition to show the security against arbitrary attacks (active).
