Description
A Fountain code is a code of fixed dimension and a limitless block-length. This is a new class of codes with very interesting applications. In this talk I will show how Fountain codes can be applied to the problem of reliable, robust, and speedy transmission of data over a heterogeneous network from one or multiple transmitters to one or multiple receivers. I will then talk about applications to the design of reliable end-to-end data transmission systems in unreliable unicast, multicast, or even peer-to-peer networks. In the last part of the talk I will introduce two classes of probabilistic Fountain codes that are used in commercial systems today. These codes, called LT- and Raptor codes, have very efficient encoding and decoding algorithms. I will introduce the mathematical theory of these codes and give some insights into their design.

Polytopes in the Fiat-Shamir with Aborts Paradigm
Speaker : Hugo Beguinet - ENS Paris / Thales
The Fiat-Shamir with Aborts paradigm (FSwA) uses rejection sampling to remove a secret’s dependency on a given source distribution. Recent results revealed that unlike the uniform distribution in the hypercube, both the continuous Gaussian and the uniform distribution within the hypersphere minimise the rejection rate and the size of the proof of knowledge. However, in practice both these[…]-
