Indifferentiability of Confusion-Diffusion Networks

Yevgeniy Dodis, Tianren Liu, Martijn Stam, and John Steinberger

Abstract

We show the first positive results for the indifferentiability security of the confusion-diffusion networks (which are extensively used in the design of block ciphers and hash functions). In particular, our result shows that a constant number of confusion-diffusion rounds is sufficient to extend the domain of a public random permutation.
