GROLLEAU

My name is Benjamin GROLLEAU, I am currently a work-study engineering student at Enseirb-Matmeca, where I am enrolled in a program in Network and Computer Science. My background is centered on network and application cybersecurity, particularly through my role as an R&D apprentice within the CATIE. There, I develop a secure demonstrator on the open-source 6TRON platform. Its goal is to prevent cyber-physical attacks such as power analysis or firmware extraction. It therefore incorporates advanced technologies and solutions such as ARM TrustZone and TrustedFirmware-M, as well as an external SecureElement component. All of this is based on the Zephyr real-time operating system, aimed at preventing cyber-physical attacks and optimizing resource-constrained devices.

Alongside my academic journey, I have always been actively involved in student associations. I began as president of the Air-RT association during my undergraduate studies, then joined several associations at ENSEIRB-MATMECA. There, I notably held the position of web manager and secretary of the student union, with the main mission of redesigning and managing the website https://bde.eirb.fr . These roles allowed me to develop skills in web development, project management and team coordination. One of the most memorable projects was setting up beehives within the school, a nod to our mascot: the bee.

During my studies, I also had the opportunity to complete a three-month research internship at the Federal University of Rio Grande do Sul in Porto Alegre, Brazil. This internship allowed me to work on a completely new topic for me: the automation of integrated circuit design. I used open-source EDA tools such as OpenROAD, applied to the ASAP7 technology, to compare performance and energy efficiency across different standard cell libraries. It was an enriching experience that broadened my skill set and strengthened my ability to quickly adapt to a new technical domain. Although the field is quite different from what I usually work on, I genuinely enjoyed the research aspect, and this experience made me want to continue pursuing research in the future.
