WitrynaIn this paper we present a construction keeping in mind the basic theory of annihilator immunity. This construction provides functions with the maximum possible … WitrynaIn this paper, we first analyse the method of finding algebraic immunity of a Boolean function. Given a Boolean function f on n –variables, we identify a reduced set of homogeneous linear equations by solving which one can decide whether there exist annihilators of f at a specific degree. overhead 625
