An expanding key space method was proposed, which was based on 3 principles of the Shannon’s idea “one-time pad”, “infinite key space” and a chaotic system could make out of a determinate random number generator.
这种方法基于三条原理:Shannon的“一次一密”,“无限密钥空间”及混沌映射系统可构造一个确定性的随机数发生器。
On the basis of chaos map,a theory of block ciphers key space expand combined with the idea of "one-time pad" by shanon is constituted.
介绍一个混沌二值序列产生和实验的软件平台,利用3种混沌动力学模型,即一阶时延模型、Logistic模型和Lorenz模型产生加密序列,并结合Shanon的"一次一密"思想,建立一种基于混沌映射的"分组密码密钥空间拓展"理论,很好地解决DES加密算法密钥空间小的问题,实现了一种混沌的DES变形密码算法。
