常用两种加密算法的特点及应用分析

The Characteristics and Applied Analysis of Two Encryption Algorithms

随着计算机网络的发展,社会对网络安全的要求也越来越紧迫。数据加密是网络安全技术中非常重要的问题,本文介绍了分组数据加密算法DES和公开密钥算法RSA,对两种算法的优、缺点进行了比较,并提出了将二者结合使用的方法。

With the development of computer network, the needs for computer network security are requested more urgently. Appending cipher to data is the most principal problem on technology of network safety. In this paper, the algorithm of divided group data encrypt algorithm DES and public key algorithm RSA are introduced, the advantage and shortage of two kinds of algorithm is compared, and the method of combined usage is put forward.
