Abstract: Differential cryptanalysis is considered as a powerful technique in the field of cryptanalysis, applied to symmetric-key block ciphers. It is a kind of chosen plaintext attack in which the cryptanalyst has some sets of the plaintext and the corresponding ciphertext pairs of his choice. These pairs of the plaintext are related by a constant difference. Generally, it is the analysis of how differences in input information can affect the resultant difference at the output. In this paper, we present step by step implementation of differential cryptanalysis of data encryption standard (DES) up to 8-rounds.
