关于对DES加密算法进行改进的构想

Construction of Methods to Improve DES

在计算机技术飞速发展的今天,数据加密技术也得到了极大的发展,而DES加密算法仍旧在加密领域中占据着主要的地位。针对DES算法的缺陷而设计的改进方案虽各据优点,但也是各有限制。本文根据目前的几种改进方法所受限制大胆提出了一种新的方案,即采用在一系列密钥中通过特殊的计算方法产生相对随机的密钥来对数据进行加密的方式,来模拟一次一密,达到对DES算法进行改良。希望此设计能给加密技术带来新的思路。

Data encryption techniques improves very quickly along with the computer science. In the field of data encryption, the DES still plays a important role. There are many design patterns for offsetting the fault of DES, but they also have limitations. This thesis suggests a new pattern which introduces a special way to generate random keys every time for encrypting data in order to improve DES. Our design in to create a new thought for data encryption techniques.
