WebDifferential cryptanalysis operates by taking many pairs of plaintexts with fixed xor difference, and looking at the differences in the resulting ciphertext pairs. Based on these … WebIn section 5 we describe what can be done to prevent linear and differential crypt-analysis attacks and make the SPN resistant. 2 Linear Cryptanalysis A linear cryptanalysis is a known plain text attack, against a block cipher. The attack was first described by Matsui in 1994 as an attack against DES [M93]. But
