Abstract

In this paper we study the attacks on some variants of DES and FEAL. Differential cryptanalysis is a form of cryptanalysis applicable primarily to the block cryptsystems but also can be used to decipher cryptographic hash functions. When used to attack a block cipher, it consists of a set of techniques for tracking the differences through the series of transformations, looking for places where the cipher exhibits non-random behavior, and using such properties in order to reveal the secret key. The first chapter describes those techniques and in the following two chapters we apply them on DES and FEAL.
