混沌理论在密码学中的应用综述

A review of application of chaos theory to cryptography

综述了混沌理论在密码学中的应用及进展状况,对其中的基于混沌理论的加密技术、密码分析技术的原理、特点与算法实现都做了阐述。另一方面,对基于混沌理论的HASH函数构造方法及其HASH碰撞分析等方面也进行了详细的阐述。并指出了它们各自的优缺点、存在的问题及应用局限性。最后,还讨论了今后进一步的研究方向。

In this paper, the author reviews the latest development and application of chaos theory to cryptography, and expounds the principles, characteristics and algorithm of cryptosystem and cryptanalysis based on chaos theory. At the same time, some constructive methods of Hash functions and analysis of Hash collision based on chaos theory are also elaborated and their advantages, disadvantages, problems and limitation in application are pointed out. Finally, the future research direction in this field is discussed.
