WebJan 1, 2014 · We investigate their performance on a large set of ciphertexts obtained by six different encryption methods, including Feistel, Vigenere, simple substitution, affine, carre de Polybe, and... Webciphertext-only attack on substitution ciphers based on neural networks. Our results are preliminary but we believe that the proposed approach is a promising step towards a more efficient and partially automated cryptanalysis of modern ciphers. In particular, our approach might be adopted to cryptanalyze existing broken ciphers,

Cryptanalysis of the Affine Cipher - Practical Cryptography
http://www.practicalcryptography.com/ciphers/classical-era/homophonic-substitution/ WebIn cryptanalysis, frequency analysis (also known as counting letters) is the study of the frequency of letters or groups of letters in a ciphertext. The method is used as an aid to … Webunicity distance for a simple substitution cipher to be as few as 50 letters of the English alphabet. Alas, he points out that it is possible to use 'ideal systems' which extend the unicity distance further and further. The traditional strategy for cryptanalysis was to "hammer the ciphertext" and extract from it the committed plaintext. ready made rabbit hutches
