Almacrypt: Cryptology Securing the Digital World

Cryptography is the basis of information security in the digital world. It protection relies on problems that are presumed to be difficult to solve. However, current knowledge in complexity is not able to guarantee the solidity of the digital armored vaults that we use to protect our secrets.

Antoine Joux received an ERC Advanced Grant to provide algorithmic tools that can differentiate the easy problems from the more difficult and therefore choose better, more resistant vaults. The aim is to avoid the use of systems that do not properly protect sensitive data.

Antoine Joux, an expert  for the UPMC cryptology chair

The Chair in Cryptography, the science of secret codes, was established at UPMC in September 2013 by the University's Foundation. At its head: Antoine Joux, a world-renowned specialist. Cryptology is at the junction between mathematics and computer science and at the heart of digital security. The Internet, mobile phones are bank cards are all everyday tools that use cryptology. This field is divided into two branches: the constructive side when cryptography creates adapted security tools and destructive side, where cryptanalysis research looks for weaknesses in systems to prove they are not entirely reliable. Antoine Joux has been a researcher in cryptography since his doctoral studies from 1990 to 93, carried out with Jacques Stern, the founding father of the field in France. Previously, he worked at the Directorate General of Armaments (DGA), where he led the scientific sub-directorate of the current French National Computer Security Agency (ANSSI) and taught at the University of Versailles Saint-Quentin. Today, Antoine Joux is not only a professor-researcher at UPMC and member of the prestigious LIP6 laboratoryNouvelle fenêtre, but also a consultant in cryptology and security at CryptoExpert.

He was awarded the Gödel Prize in June 2013, together with two other American scientists. He was rewarded for having, in 2000, used the concept of coupling on curves, which had been considered a tool for a mathematical attack, to build an encryption system that offers features hitherto unknown. This concept will help to develop protocols in the new societal applications such as currency and e-voting.

Antoine Joux also just received the distinction of 2014 IACR FellowNouvelle fenêtre for his work on the calculation of discrete logarithms and hash functions.

the UPMC Fondation

The UPMC Foundation Chairs aim to develop research expertise and / or teaching on strategic themes for UPMC: in science, medicine or at the interface of the two disciplines. The field of activity of the chair is determined jointly by UPMC and the chair’s sponsor.
