Academic Year  


Teachings held in other departments in the academic year 2020/2021

Over the last twenty years, my research activity has been concerned mainly with cryptography and, in particular, to reducing the gap between theory and practice in cryptography. My research agenda mostly concentrates on foundational issues inspired by practical needs and on questions related to the realizations of secure and efficient cryptographic constructions addressing such needs. Such topics include, for example, password based cryptography, electronic voting and, in particular, cryptographic primitives with special properties (e.g. homomorphic signatures and MACs, homomorphic/functional encryption).

In the early stages of my career I was also interested in the theory of machine learning.
