Florentin Putz is a researcher at the Secure Mobile Networking Lab. His research focuses on strong authentication on all layers, for example: Improving the design of authentication tokens, or innovative physical layers for device pairing (e.g., acoustic communication), or applications using the FIDO2 standards. He received his B.Sc. (2016) and M.Sc. (2019) degrees from Technical University of Darmstadt, Germany. During his master’s studies, he was a visiting graduate student at the University of British Columbia, Canada. He is recipient of the Best Student Award (for the best master’s degree at the electrical engineering department), the Datenlotsen Award (for an outstanding master’s thesis), and the KuVS Award 2020 (nationwide award from the German special interest group on Communication and Distributed Systems).

Looking for HiWis

For the winter term 2022/23, I’m looking for HiWis that help me to conduct user studies. Please drop me an email if you are interested.
