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.

CryptoVerif: a computationally-sound security protocol verifier
Orateur : Bruno Blanchet - Inria
CryptoVerif is a security protocol verifier sound in the computational model of cryptography. It produces proofs by sequences of games, like those done manually by cryptographers. It has an automatic proof strategy and can also be guided by the user. It provides a generic method for specifying security assumptions on many cryptographic primitives, and can prove secrecy, authentication, and[…]-
