在密码学中,块密码,英语:Block cipher ,又被称为分组加密或者叫分块加密,是对称加密的一种常见形式。如果你想理解常见的对称加密算法,例如 AES/DES ,那么首先要理解什么是块密码。 基本介绍 先来做一下块密码的简介。当代的块密码的思路是基于信息论之父香农在1949年提出的密码思想,在1970年代被研发出来的。 块...
Usually the security of Feistel type block cipher algorithm depends on the structure of its round function. More specifically, the present invention relates to the round function structure of the Feistel type block cipher algorithm, in the instance that the round input data block is divided into ...

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 ...
a ciphertext that depends on all plaintext blocks processed before it in a data stream, ensuring that each ciphertext block is dependent on all the previous blocks. Each plaintext block isXORed(exclusive OR) with the previous ciphertext block before being encrypted with the cipher algorithm. ...
Block cipher Ablock cipheris a second form of cipher, which operates over a group of bytes. Ablock cipheralgorithm uses two tactics to achieve a strong level of encryption. These tactics are confusion (which substitutes one symbol for another) and diffusion (which spreads one plain text symbol...
