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. VC6 upload files to complete the project directory . AES encryption algorithm that is Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, a block encryption standard adopted by the U.S. federal government . This standard is used to replace the original DES, has been widely analyzed and multi used around the world . After five years of the selection process , the Advanced Encryption Standard by the American National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and May 26, 2002 became effective standards . AES algorithm based on permutation and substitution operations. Data re- arrangement is arranged , is replaced with a replacement unit of data to another . AES using several different methods to perform alignment and replacement operations. AES is an iterative , symmetric key block password , it can use 128, 192, and )

ASFDSAF
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:)

ECC
椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)
