Information Structures for Privacy and Fairness

This seminar will talk about some of the privacy risks of these systems and will describe some recent attacks. It will also discuss why they sometimes fail to deliver. Finally, we will also show that

Dans cet exposé, à la fois historique et technique, nous expliquerons tout d'abord comment les machines à chiffrer Enigma ont pu être cryptanalysées durant la deuxième guerre mondiale. Nous nous

In the next three sessions, I will explain how to reduce the key size of code-based cryptosystem. Circulant matrices are the central point in many attempts to reduce the key size of code-based

In this session we will see that generalized Reed-Solomon codes behave differently than random codes with respect to the star operation. Thus we can define a distinguisher for Generalized Reed

LDPC codes have an interesting feature: they are free of algebraic structure. We will study in detail this proposal for the McEliece cryptosystem in this session. LDPC codes were originally

In this session, we will talk about using subcodes of a Generalized Reed–Solomon code for the McEliece Cryptosystem. Recall that to avoid the attack of Sidelnikov and Shestakov, Berger and

Welcome to this MOOC which is entitled: code-based cryptography. This MOOC is divided in five weeks. The first week, we will talk about error-correcting codes and cryptography, this is an introduction

This is the last session where we will talk about reducing the key size. Here we will introduce the MDPC codes. In 2012, the MDPC codes were proposed for the McEliece schemes. An MDPC code is a

À l'ère du tout connecté, la question de la sécurité de nos données personnelles est devenue primordiale. Comment faire pour garder le contrôle de nos données ? Comment déjouer les pièges de plus en
