摘要
在混沌通信系统中,混沌系统的同步是关键,尤其是超混沌系统的同步。本文采用了一种基于观察器的离散混沌系统的同步技术,即用一个标量信号来同步离散混沌系统,对离散混沌同步加密技术进行研究。该方法利用了高复杂度的超混沌信号以增强载波信号的随机性以及Deat-Beat同步加密的复杂性,并且将这种技术应用于数字签名领域,得到了很好的加密效果。
In the chaos-based communication system, the synchronization of the chaos is the key, especially the hyperehaos synchronization, This paper used a technology of discrete-time hyperehaos synchronization that is an observer-based technology which used a scalar signal to synchronize the discrete-time chaos system. The method used the hyperchaotie signal to enhance the randomness of carrier wave and the complexity of Dead-Beat synchronization eneryption is used,and then applied to the digital signature field, achieved better eneryption effect.
