Dynamic Substitution in Stream Cipher CryptographyA PagePageTerry Ritter
using large completely nonsingular matrix based substitution permutation networks can effectively improve cipher security in relation to differential cryptanalysis.───使用大规模的基于全奇异矩阵的代替置换网络可有效地提高分组密码抗差分密码分析的安全性。 In cryptography, an early example of monoalphabetic, or...
In cryptography, a substitution cipher is a method of encrypting by which units of plaintext are replaced with ciphertext, according to a fixed system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The re...

A cipher in which the characters of the original message are replaced by other characters according to a key. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. Want to thank TFD for its existence?Tell a friend about us, add ...
In cryptography , a cipher produced by a composition of a number of substitution and transposition ciphers. 密码学中, 由替代密码和置换密码结合使用而构成的一种密码. 来自期刊摘选 20. The single segment substitution lines ( SSSLs ) were perfect materials for analysis of gene especially for QTL. ...
Generate a random key, called the 'parent', decipher the ciphertext using this key. Rate the fitness of the deciphered text, store the result. Change the key slightly (swap two characters in the key at random), measure the fitness of the deciphered text using the new key. ...
