An Approach of Zero Correlation Linear Cryptanalysis
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 5
Abstract
Differential and Linear Cryptanalysis are two most popular techniques that have been widely used to attacks block ciphers to reveal its weakness in substitution and permutation network. Most of the block ciphers which are resistant against Differential and Linear Cryptanalysis may not be immune to their latest extensions such as Impossible Differential Cryptanalysis (IDC) and Zero Correlation Linear Cryptanalysis (ZCLC). These techniques use the statistics of distinguishing the correct key and incorrect key from probability distribution of impossible differentials and linear approximation respectively. Most of IDC and ZCLC are based on miss in middle technique and are independent of non linear components. In this paper, the method used by ZCLC is explained and the block ciphers which have been attacked by ZCLC and multidimensional ZCLC have been stated. The links between IDC and ZCLC have been also projected.
