WebCryptanalysis is the process of studying cryptographic systems to look for weaknesses or leaks of information. Cryptanalysis is generally thought of as exploring the weaknesses of the underlying mathematics of a cryptographic system but it also includes looking for weaknesses in implementation, such as side channel attacks or weak entropy inputs. http://practicalcryptography.com/cryptanalysis/stochastic-searching/cryptanalysis-caesar-cipher/

WebSometimes values are reported without the normalizing denominator, for example 0.067 = 1.73/26 for English; such values may be called κp ("kappa-plaintext") rather than IC, with κr ("kappa-random") used to denote the denominator 1/c (which is the expected coincidence rate for a uniform distribution of the same alphabet, 0.0385=1/26 for English). WebLinear cryptanalysis is a powerful method of cryptanalysis of block ciphers introduced by Matsui in 1993 [ 1 ]. The attack in its current form was first applied to the Data Encryption Standard (DES), but an early variant of linear cryptanalysis, developed by Matsui and Yamagishi, was already successfully used to attack FEAL in 1992 [ 12 ].
