摘要
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.
A software platform is brought forward,which can be used to generate and evaluate chaotic binary sequences.Three typical kinds of chaotic dynamics model are utilized to generate encryption sequences.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.The problem of 'key space shortage' is successfully solved and a new DES algorithm based on chaos map is created.
