基于耦合Logistic映射的伪随机位发生器及其在混沌序列密码算法中的应用

摘要

In this paper, the recent progress on chaotic cryptography is summarized firstly. Then a novel pseudorandom bit generator based on coupled Logistic maps is proposed. Theoretical analysis and numerical experiments illustrate that it is superior to those in the literature. Finally, some examples are given to demonstrate the applications in the stream-cipher algorithms.
