本文介绍Block Cipher分组密码的分组模式 楔子 由于分组密码算法一次只能对固定长度的明文进行加密。为此对于较长的明文而言,我们需要先按分组长度对明文进行分组处理。然后根据分组模式决定如何对这些分组进行加密、解密 ECB模式 ECB模式(Electronic CodeBook mode,电子密码本模式)下,其会对各明文分组直接进行加密。同时,由...

A block cipher is made up of two algorithms, E and D. These are encryption and decryption algorithms. Both of these algorithms take N-bit plaintext as input and output the same number of bits as output.So it maps N bits of inputs to N bits of outputs.Block ciphers are typically ...
