m0leCon 2019: Guglielmo Morgari on Quantum Computing & Cryptography 🔐

m0leCon 2019 Turin, Italy - 30/11/2019

Theorized in the early 80s, quantum computing has long been considered an interesting abstract model without concrete possibilities of realization. In recent years, however, the scientific community has begun to believe that quantum computer could actually appear shortly and today some prototypes are already available, albeit poorly efficient.
Quantum computing is thus receiving an increasing attention, especially because its realization would make most public key cryptography techniques completely vulnerable, severely jeopardizing the security of current information systems.
This threat is usually addressed along two technologically distinct directions. On the one hand the use of new PQC (Post Quantum Cryptography) algorithms, based on mathematical conjectures and able to resist the cryptanalysis capabilities of the quantum computer; on the other hand, the use of QKD (quantum key distribution) solutions, whose security is based instead on the principles of quantum mechanics.
The talk will give an overview of the described scenario, focusing on the technical aspects and the applicative implications.
