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 differences, probabilities are assigned to possible keys. As more pairs are analyzed, the probability concentrates around a smaller number of keys.

WebDifferential cryptanalysis is the first published attack that is capable of breaking DES in less than 255 encryptions. The scheme, as reported in [BIHA93], can successfully cryptanalyze DES with an effort on the order of 247 encryptions, requiring 247 chosen plaintexts. Although 247 is certainly significantly less than 255, the need for the ... WebStandard (DES). First by a small 3 rounds DES and then the full 16 rounds DES.
