Title: Using Multiple Differentials... On the LLR and chi^2 Statistical Tests.

Abstract In parallel to similar extensions in linear cryptanalysis, a few papers about multiple differential cryptanalysis of block ciphers have been recently published. In the recent works published in SAC 2012 and SCN 2012 different and complementary approaches how to use information from multiple differentials were presented. During this presentation we will explain how the LLR and the chi^2 statistical test can be used in the differential cryptanalysis context to handle information from number of differential or truncated differential. We present and compare different techniques, classify them into families and discuss their relevance for cryptanalysis in light of available experimental results.
