Title: Zero-Correlation Linear Cryptanalysis of Reduced-Round Camellia and CLEFIA

Abstract: Zero-correlation linear cryptanalysis has been proposed and some techniques have been studied such as multidimensional zero-correlation distinguisher and integral distinguisher etc. In this talk, we show how to use FFT technique to reduce the time complexity of zero-correlation cryptanalysis and give the attacks on Camellia-128 and Camellia-192. At the same time, the multidimensional zero-correlation linear attacks on CLEFIA-192 and CLEFIA-256 are given.
