Welcome, everybody. I'm happy new year. Welcome to the new series of volumes of 2026. So it's my great pleasure to introduce Gilbath, who of course is no stranger to India, Sofia Antipolis. Gigi received the PhD in mathematics from the University of Manchester in the UK in 1993 and the Abilitation de Rijad Roshash from the University of Nice in 2004. He was the head of the Everest team on formal methods and security at Inria here for many years and he also held positions in Portugal, Sweden and the Netherlands. Currently, he is scientific director and founding scientific director of the Max Bank Institute for Security and Privacy in Bohem in Germany and a part-time research professor at the India Software Institute in Madrid in Spain. His research interests include programming languages, programming publications, security, privacy and cryptography and he has a very large number of extremely influential publications and also has directly influenced standards which are used in the real world. It's my great pleasure looking forward to hearing about the formal verified post-Prompton photography. Thanks very much for the invitation and for the nice introduction. Maybe I should start by complimenting your day also. Yeah, it was the Everest project. The kind of nickname was Czechoslovak because we had two many Argentineans, so it was called Czechoslovak. One never rest, so that was kind of the two nicknames for the project. And it's actually a while we were at Inria that we started this work on cryptography. It was a little strange story that was this professor of mathematics at the University of Niz, Andrej Chovic, who called me one day and said, I have this two then. They want to do cryptography around 2002 and we started weeks on formalization stuff. And then we really started seriously with Benjamin. I guess around 2005, so it's been going on for about 20 years. And so I will try to give a very high level overview. Today, last time I attended the Morganston Colokium was maybe 20 years ago, so I was very broad audience. So I prepared for people who are just have background in computer science, but it's not very technical if you have technical question, you can kind of interrupt me. Okay, and yeah. So I will try to give a very high level introduction about why we want to formally verify cryptography, and then try to give a very crushed course on cryptography, high level, and then dive into what we've been doing. And given the audience, I think I can go quite quickly over the motivation. Cryptography is actually a pillar of the kind of digital societies. So a lot of time when you actually consult your parents to document some other internet and so on, you will be using cryptography also for central communication. So it's very hard to think about being able to access digital surveys with other kind of support for cryptography. And I think it stands as the... The first national place within multidisciplinary games, which is itself a big research area, but the market is already, that's all right. Okay, I will not move. I can also yell after ten years in Spain, I can do this, but okay, I will not move mostly. So it stands in a very... It stands in a very special place in computer security. It's often considered as a bigger success story. There is a lot of discussion whether computer security is a science, or whether there can be a science of computer security, and cryptography is the success story in the sense that it has a very good mathematic…
