Fabio Banfi
Cryptographer and Security Engineer
About Me
I work as a security engineer at Zühlke Engineering AG. Prior to that, I completed my PhD in the Cryptography and Information Security group at ETH Zurich under the supervision of Prof. Ueli Maurer. I hold a Bachelor's and Master's degree in Computer Science from ETH Zurich.
My research interests include composable security, anonymity, length-preserving encryption, anamorphic encryption, self-sovereign identity, and quantum cryptography.

Projects
A puzzle game where players prove in zero-knowledge (via zk-SNARKs) that they found the empty cell in a dotted grid, without revealing its location.
[ open ]
A simple word association game deployed as a dapp, where you guess a word that matches a given prompt and see how many others think like you. Play to find common connections, or add new word pairs to expand the game and challenge others!
