Abstract

Studying algebraic immunity of Boolean functions is recently a very important research topic in cryptography. It is recently proved by Courtois and Meier that for any Boolean function of n-variable the maximum algebraic immunity is @?n2@?. We found a large subclass of Maiorana McFarland bent functions on n-variable with a proven low level of algebraic immunity =
