WebIn cryptography, DES-X (or DESX) is a variant on the DES (Data Encryption Standard) symmetric-key block cipher intended to increase the complexity of a brute-force attack. The technique used to increase the complexity is called key whitening . The original DES algorithm was specified in 1976 with a 56-bit key size: 2 56 possibilities for the key. WebIntroduced by Martin Hellman and Susan K. Langford in 1994, the differential-linear attack is a mix of both linear cryptanalysis and differential cryptanalysis . The attack utilises a differential characteristic over part of the cipher with a probability of 1 (for a few rounds—this probability would be much lower for the whole cipher).

WebDifferential cryptanalysis studies how the differences evolve through the various rounds and various operations of the cipher. Usually it is assumed that the difference operation is the exclusive-or (XOR) operation, and we will make this assumption herein as well.
