Cryptanalyse

Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. In the broadest sense, it is the study of how differences in information input can affect the resultant difference at the output. In the case of a block cipher, it refers to a set of techniques for tracing differences through the network of transformation, discovering where the cipher exhibits non-random behavior, and exploiting such … WebAbraham Sinkov (August 22, 1907 – January 19, 1998) was a US cryptanalyst.An early employee of the U.S. Army's Signals Intelligence Service, he held several leadership positions during World War II, …

http://www.theamazingking.com/crypto-linear.php WebI am trying to cryptanalyse multiple cipher–texts that I know are encrypted by different Affine ciphers. I have already analysed the frequency that each character occurs, and compared it to a frequency table of the languages the plain-texts could be in and as a result have a pretty decent idea of what a few characters could correspond to.
