Statistics of correlation and differentials in block ciphers
Joan Daemen, Vincent Rijmen · 2006
In this paper, we derive the statistical distributions of difference propagation probabilities and input-output correlations for random functions and block ciphers, for most of them for the first time. We show that these parameters have distributions that are well-studied in the field of statistics such as the normal, Poisson, Gamma and extreme value distributions. For Markov ciphers...
