Title:
Correlations Between (Nonlinear) Combiners of Input and Output of Random Functions and Permutations

Authors: Subhabrata Samajder, Palash Sarkar

Abstract:

Linear cryptanalysis considers correlations between linear input and output combiners for block ciphers and stream ciphers. Daemen and Rijmen (2007) had obtained the distributions of the correlations between linear input and output combiners of uniform random functions and uniform random permutations. The present work generalises these results to obtain the distributions of the correlations between arbitrary input and output combiners of uniform random functions and uniform random permutations.
