摘要
数据通信是依照一定的通信协议,利用数据传输技术在两个终端之间传递数据信息的一种通信方式和通信业务。随着数据通信的迅速发展而带来了数据失密问题。信息被非法截取和数据库资料被窃的事例经常发生,在日常生活中信用卡密码被盗是常见的例子。所以数据加密成为十分重要的问题,它能保证数据的安全性和不可篡改性。 RSA加密算法以它难以破译的优点,被广泛的使用在电子商务和VPN中。
本文针对非对称性加密RSA算法,采用软件Visual C++。根据模乘法运算和模指数运算的数学原理所编写的程序在进行测试后,能够通过输入两个素数进行运算从而实现明文与密文之间的转换,然后通过对公钥和私钥的管理,对所传输的数据进行保护,让数据只能由发送者和接收者阅读,以达到数据通信中数据无法被他人破译的目的。

Abstract
munications in accordance with munication protocols, the use of data transmission technology in the transmission of data between two terminals as a means munication of information munication business. With the rapid development of munications and has brought the issue of promise. Unlawful interception of information and database information on frequent instances of theft, credit card in their daily lives stolen passwords is mon example. Therefore, data encryption has e a very important issue, it can ensure data security and can not be tamper with nature. RSA encryption algorithm to the merits of it difficult to decipher, was widely used in the merce and VPN.
In this paper, asymmetric RSA encryption algorithm, the use of software for Visual C + + programming. According to Die multiplication and modular exponentiation by the mathematical principles in the preparation of test procedures can be adopted for the importation of two prime numbers puting in order to achieve explicit conversion between the ciphertext, and then through a public key and private key management, for the transmission of data protection, so that data can only be made by the sender and the recipient to read, in order to achieve munications data can not be the purpose of deciphering the others.
Keywords: RSA algorithms, munication, encryption, decryption.
