31Public-key cryptography — In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of that private key …
32Bombe — In the history of cryptography, the Bombe was an electromechanical device used by British cryptologists to help break German Enigma machine signals during World War II. The bombe was designed by Alan Turing, with an important refinement suggested …
33One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… …
34Advanced Encryption Standard — Infobox block cipher name = AES caption = The SubBytes step, one of four stages in a round of AES designers = Vincent Rijmen, Joan Daemen publish date = 1998 derived from = Square derived to = Anubis, Grand Cru related to = certification = AES… …
35Data Encryption Standard — The Feistel function (F function) of DES General Designers IBM First publis …
36Japanese cryptology from the 1500s to Meiji — The cipher system that Uesugi used is basically a simple substitution usually known as a Polybius square or “checkerboard.” The i ro ha alphabet contains forty eight letters, so a seven by seven square is used, with one of the cells left blank.… …
37Slide attack — The slide attack is a form of cryptanalysis designed to deal with the prevailing idea that even weak ciphers can become very strong by increasing the number of rounds, which can ward off a differential attack. The slide attack works in such a way …
38Chaocipher — The Chaocipher [1] is a cipher method invented by J. F. Byrne in 1918 and described in his 1953 autobiographical Silent Years[2]. He believed Chaocipher was simple, yet unbreakable. Byrne stated that the machine he used to encipher his messages… …
39Three-pass protocol — In cryptography, the three pass protocol for sending messages is a framework which allows one party to securely send a message to a second party without the need to exchange or distribute encryption keys. This message protocol should not be… …
40Rotor machine — In cryptography, a rotor machine is an electro mechanical device used for encrypting and decrypting secret messages. Rotor machines were the cryptographic state of the art for a brief but prominent period of history; they were in widespread use… …
