Title:
Indifferentiability of Confusion-Diffusion Networks

Authors: Yevgeniy Dodis, Tianren Liu, Martijn Stam, 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.
