题目:某个公司采用公用电话传递数据,数据是四位的整数,在传递过程中是加密的,加密规则如下:
每位数字都加上5,然后用和除以10的余数代替该数字,再将第一位和第四位交换,第二位和第三位交换。
1.程序分析:
2.程序源代码:(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows:
Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange.
1. The program analysis:
2. The source code:)

Caesar-code
凯撒密码作为一种最为古老的对称加密体制,在古罗马的时候都已经很流行,他的基本思想是:通过把字母移动一定的位数来实现加密和解密。例如,如果密匙是把明文字母的位数向后移动三位,那么明文字母B就变成了密文的E,依次类推,X将变成A,Y变成B,Z变成C,由此可见,位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys. Personal originality.)

AES_CMAC
通过C语言实现的AES CMAC加密和解密算法。上传文件为完整的VC6工程目录。AES加密算法即密码学中的高级加密标准(Advanced Encryption Standard,AES),又称Rijndael加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。经过五年的甄选流程,高级加密标准由美国国家标准与技术研究院 (NIST)于2001年11月26日发布于FIPS PUB 197,并在2002年5月26日成为有效的标准。AES 算法基于排列和置换运算。排列是对数据重新进行安排,置换是将一个数据单元替换为另一个。AES 使用几种不同的方法来执行排列和置换运算。 AES 是一个迭代的、对称密钥分组的密码,它可以使用128、192 和 256 位密钥,并且用 128 位(16字节)分组加密和解密数据。与公共密钥密码使用密钥对不同,对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据的位数与输入数据相同。迭代加密使用一个循环结构,在该循环中重复置换和替换输入数据。(AES CMAC encryption and decryption algorithm C language.
