WebCPU instructions on a 64-bit microprocessor, which leads to 222 DES com-putations per second with a single microprocessor working at 1 GHz. So far, the best known attack on DES is Matsui’s linear cryptanalysis ([11, 12]). In the original paper, it is claimed that the complexity should consist in 243 DES computations on average. This leads to ... The Data Encryption Standard is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography. Developed in the early 1970s at IBM and based on an earlier design by Horst F…

WebNov 12, 2012 · In this paper, we apply a new cryptanalytic attack on DES and Triple-DES. The implemented attack is a known-plaintext attack based on neural networks. In this … WebIn cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher. Attacks have been developed for block ciphers and stream ciphers. Linear cryptanalysis is one of the two most widely used attacks on block ciphers; the other being differential cryptanalysis .

WebDifferential cryptanalysis of DES [1] was the first method capable of breaking DES faster than exhaustive search. It is a statistical attack [12] which requires 247 chosen plaintexts to break the DES cipher. It is based on the linearity of most of the operations used in DES; WebDES-X also increases the strength of DES against differential cryptanalysis and linear cryptanalysis, although the improvement is much smaller than in the case of brute force attacks. It is estimated that differential cryptanalysis would require 2 61 chosen plaintexts (vs. 2 47 for DES), while linear cryptanalysis would require 2 60 known ...
