WebIn 1990, Eli Biham and Adi Shamir introduced differential cryptanalysis, a chosen-plaintext attack for cryptanalyzing ciphers based on substitutions and permutations. Applied to … 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.

WebStraightforward brute force attack on DES requires 255 plaintexts Using differential cryptanalysis, DES can be broken with 24747 plaintexts. But finding appropriate plaintexts takes some trials and so the total amount of effort is 255.155.1 which is more than straight forward brute force attack DES is resistant to differential cryptanalysis Web" Differential cryptanalysis is a method which analyzes the effect of particular differences in plaintext pairs on the differences of the resultant ciphertext pairs. These differences can be used to assign probabilities to the possible keys and to locate the most probable key.
