A function f : Fpn → Fpn is planar, if f(x+a)-f(x) = b has precisely one solution for all a, b ε Fpn, a ≠ 0. In this paper, we discuss possible extensions of the switching idea developed in [1] to the case of planar functions. We show that some of the known planar functions can be constructed from each other by switching.
