WebA cipher uses a system of fixed rules -- an encryption algorithm -- to transform plaintext, a legible message, into ciphertext, an apparently random string of characters. Ciphers can be designed to encrypt or decrypt bits in a stream, known as stream ciphers. WebTweakable Block Ciphers 589 Fig. 1. (a) Standard block cipher encrypts a message M under control of a key K to yield a ciphertext C.(b) Tweakable block cipher encrypts a message M under control of not only a key K but also a “tweak” Tto yield a ciphertext C.The “tweak” can be changed quickly and can even be public. (c) Another way ofrepresenting …
