Summer Seminars on Cybersecurity: Dario Fiore (IMDEA) - "Cryptography for Privacy and Integrity of Computation on Untrusted Machines"
Mercoledì, 23 June, 2021 - 11:00
Abstract: Due to phenomena like the ubiquity of the Internet and cloud computing it is increasingly common to store and process data on third-party machines. In spite of its attractive aspects, this trend raises a number of security concerns, including: How to ensure that the results computed by third parties are correct (integrity) and no unauthorized information is leaked (privacy)?
The current way to deal with these problems is to trust third-party machines under legislation guarantees—an assumption that unfortunately is often contradicted. In contrast, in this talk I will discuss how to address these questions in the challenging scenario where third-party machines are untrusted. I will give an overview of the cryptographic problems related to computing securely on untrusted machines, their state of the art, and the challenges that are ahead of us towards their cost-effective application.
Bio: Dario Fiore is an Associate Research Professor at the IMDEA Software Institute in Madrid. Before joining IMDEA in 2013, he obtained a PhD in computer science from University of Catania in 2010, and then held postdoc positions at the Max Planck Institute for Software Systems in Germany, the New York University in the United States, and the École Normale Supérieure of Paris in France. Dario’s research interests are on theoretical and practical aspects of cryptography, and its applications to security and privacy. He is a recipient of an ERC Consolidator Grant (2020), and he co-authored over 50 peer-reviewed research papers that have been published in flagship international conferences and journals in the areas of Cryptography and Security, and have attracted so far over 2500 citations.
