基于观测器同步的超混沌系统加密算法研究

在混沌通信系统中，超混沌系统同步技术越来越受到重视。采用一种基于观测器的超混沌同步技术，实现对数据的加密。首先利用一维Logistic混沌系统产生混沌序列，通过与明文的结合产生出新的序列，在理想信道中进行传输，利用观测器同步最终在接收端恢复出这一序列，从而最终恢复出明文。通过仿真实验验证了该方法的有效性，此方法有很好的加密效果。

The Research of Digital Signature Technology Based on Observer Synchronization with Hyperchaotic Systems

In the chaotic communication systems,more and more attention is paid on the hyperchaotic synchronization technology.In this paper,an observer-based synchronization technology is used for the encryption of data.At first,a Logistic chaotic system produce a chaotic sequence,combined with the original information there comes out a new sequence,then the new one is transported in the channel,at last,with the observer-based synchronization technology,the sequence is recovered,and ultimately the original informatio...
