Fabrizio Sisinni

Fabrizio Sisinni is a PhD student at Technical University of Denmark (DTU), in the Cybersecurity and Engineering section. His PhD project aims to improve a central technique for Quantum Random Oracle Model security proofs, namely the One Way to Hiding Lemma, and to study how to deal with decryption failures in Public Key Encryption schemes.

Before starting his PhD, Fabrizio was a student at the University of Pisa, for both the bachelor’s degree, in Mathematics, and the master’s degree, in Theoretical Algebra. For his master’s thesis, Fabrizio collaborated with KU Leuven and worked on Isogeny-based cryptography.

Fabrizio has a strong background in algebraic number theory, elliptic curves, and mathematical methods applied to cryptography, especially to isogeny-based and lattice-based cryptography. His research areas are Provable Security and Post-Quantum Cryptography, mainly interested in lattice-based cryptography and security reductions.
