摘要

提出了一种用于混沌密码系统通信的离散延迟混沌系统的同步方法。为了提高传输的安全性，将延迟注入到多项式混沌离散系统中。将译码问题重新表述为LPV系统的未知输入观测器设计问题。以一个超混沌延迟系统的同步为例，表明了该方法恢复信号安全传输的有效性。

Synchronization of chaotic time-varying delayed discrete-time systems using unknown input observers

In this paper, synchronization of discrete-time delayed chaotic systems is proposed for chaotic cryptosystem communication. The delay is injected into a polynomial chaotic discret-time system in order to increase the degree of the transmissions security. The deciphering is reformulated as an unknown input observers design problem for LPV systems. The considered case of synchronization of an hyperchaotic delayed system shows the efficiency of the proposed approach to recover secure transmission of a signal.
