Abstract:

A characterization of the algebraic immune Boolean functions is presented by means of the covering vectors. A sufficient and necessary condition is given that the algebraic immunity of a Boolean function is not more than a fixed value. This result is used to describe a characterization of the algebraic immune of normal Boolean functions. It is also shown that the upper bound of the algebraic immunity of -normal Boolean functions is .
