摘要
分组密码是数据通讯中最常用的数据加密方式,以DES为例分析现有分组加密算法的安全隐患,并提出了可变密钥加密和变长密文输出两个新思路,可应用于所有现有分组加密算法以提高安全性,并就该方法的安全性、效率、具体应用做出了分析。
The block algorithm is the most common way of data encryption in communication. The hidden trouble of current block algorithm is analyzed. Two new ideas of the changeable key and the flexible output applied to all block algorithm is presented. An analysis of their security, efficiency and application is made.
