Ciao! :) I'm
Kien Tuong Truong
I am a PhD student in the Applied Cryptography Group at ETH Zurich, supervised by Prof. Kenny Paterson.
I am interested in real-world deployments of cryptography, with a focus on attacks, especially on messaging apps.
Yes, I'm that guy who did that thing at the Rump session.

(More) About Me
Before starting my PhD, I completed my Master's degree in Cybersecurity at ETH Zurich and EPFL with a thesis on the Threema encrypted messenger. I also hold a Bachelor's degree in Computing Engineering from the Politechnic University of Milan (Politecnico di Milano).
I (used to) play CTFs as part of various teams, including Tower of Hanoi, Mhackeroni, Flagbot, and Organizers and I was part of the 2023 and 2024 rosters for Team Italy. I was captain of the Politecnico di Milano team in the national CyberChallenge.IT competition in 2020, reaching national 2nd place.
I enjoy running, swimming, cycling, hiking in the beautiful Swiss mountains, trying out new foods, trying out specialty cafes, and I sometimes like to subject myself to the pain of web development.
