Description: 置换密码算法的原理是不改变明文字符，只将字符在明文中的排列顺序改变，从而实现明文信息的加密。置换密码也叫换位密码。试编程实现矩阵换位密码。它的加密方法是将明文中的字母按照给定的顺序安排在一个矩阵中，然后用根据密钥提供的顺序重新组合矩阵中的字母，形成密文。-Permutation cipher does not change the principle is expressly characters, only characters in the explicit change in order to achieve explicit information encryption. Password replacement is also called transposition password. Programming test matrix transposition password. Its encryption method is to express the letter in accordance with the order given in a matrix, and then use the key provided in accordance with the order re-arrangement of the letters in the matrix to form a ciphertext.

Description: Encryption algorithms are becoming
more necessary to ensure data is securely transmitted
over insecure communication channels. FOX is
a recently developed algorithm and its structure is
based on the already proven IDEA (International
Data Encryption Algorithm) cipher.
FOX is a symmetric (private key) block cipher. Its
top-level structure uses the Lai-Massey scheme and
the round functions used in the scheme are substitution
permutation networks (SPN). Its flexibility lies
in the fact that it can be efficiently implemented in
hardware and software. We report some of the first
results of implementing the cipher on an FPGA Platform: |

Description: 凯撒密码（caeser）是用于加密通过信使传递的作战命令。置换加密的优点就在于它易于实施却难于破解。发送方和接收方很容易事先商量好一个密钥，然后通过密钥从明文中生成密文，即使敌人获取密文，通过密文直接猜测其代表的意义，在实践中是不可能的。
在密码学中存在着各种各样的置换方式，但所有不同的置换方式都包含2个相同的元素：密钥和协议(算法)。凯撒密码的密钥是x，算法是将普通字母表中的字母用密钥对应的字母替换。(The Kaiser code (Caeser) is the operational command used to encrypt messages delivered by messenger. The advantage of permutation encryption is that it is easy to implement but difficult to break. The sender and receiver easily beforehand a key, and then through the key generation from the plaintext ciphertext, even if the enemy gets through the ciphertext ciphertext, directly guess the meaning, in practice is not possible.
There are many kinds of permutations in cryptography, but all different permutations have 2 identical elements: key and protocol. The key to the Kaiser code is x. The algorithm replaces the letters in the ordinary alphabet with letters corresponding to the key.) Platform: |
