Some results concerning global avalanche characteristics of two q-ary functions

The global avalanche characteristics criteria was first introduced by Zhou et al. (Inform. Sci. 180(2) (2010) 256-265). This article is concerned with some new bounds on global avalanche characteristics of two q-ary functions. Based on the above result we obtain a bound on σf of f ∈ Bn,q in terms of σ′ f`s of the restricted functions on Zqn−1, and construct… CONTINUE READING
