On a new invariant of Boolean functions

Abstract: A new invariant of the set of $n$-variable Boolean functions with respect to the action of $AGL(n,2)$ is studied. Application of this invariant to prove affine nonequivalence of two Boolean functions is outlined. The value of this invariant is computed for $PS_{ap}$ type bent functions.

Category / Keywords: secret-key cryptography /

Publication Info: Boolean functions, affine equivalence.
