Description
We consider properties of Boolean functions which are important when they are used as components in cryptographic primitives. We focus mainly on non-linearity. Closely related issues are the weight distribution of BCH codes with two zeros and the crosscorrelation of two m-sequences. We shall present some recently solved old problems and the methods which where required to achieve this breakthrough. Finally we shall give a perspective for further research and focus on some still open questions.

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[…]-
