Cryptographer and security engineer investigating homomorphic encryption, network authentication, and privacy-preserving systems.

Aymen Boudguiga
About

I am currently working as a research engineer at the Atomic and Alternative Energy Commission (CEA), Saclay, France, where I investigate the practical use of homomorphic encryption.

Previously, I completed a PhD jointly between Telecom SudParis and the University of Pierre and Marie Curie (UPMC), Paris, on new authentication protocols for wireless mesh networks using identity-based cryptography.

From 2013 to the end of 2017, I worked as a security engineer at Institut de Recherche en Technologie SystemX, focusing on risk analysis and security evaluation of autonomous vehicles' embedded networks.

My main research topics are applied cryptography (homomorphic encryption, lightweight crypto) and network security (authentication, risk analysis, performance analysis of security protocols).
