About me

I’m a PhD student in the Cryptology and Data Security Group at the University of Bern. My research interests lie in distributed cryptography, with a particular focus on threshold cryptosystems. I began exploring this area during my master’s thesis at Roma Tre University, where I designed a new signature scheme called D-FROST. This work, conducted in collaboration with the Bank of Italy, addresses the need for a dynamic Schnorr threshold signature scheme. My current work focuses on distributed key generation protocols, threshold signatures and quorum systems.
