变时滞系统的同步与密码学

Synchronization between variable time delayed systems and cryptography

Dibakar Ghosh, Santo Banerjee, A. Roy Chowdhury

摘要:

在这封信中,我们考虑一个原型模型,它被描述为一个自治的连续时间延迟微分方程只有一个变量。混沌已被调查与可变延迟时间和同步现象进行了研究,数值和分析使用Krasovskiii-Lyapunov函数。我们应用自适应耦合法同步,耦合方程也包含延迟调制的时间。我们还研究了密码学对这种耦合系统的影响,并借助仿真结果说明了消息提取过程。

英文摘要:

In this letter we consider a prototype model which is described as an autonomous continuous time delayed differential equation with just one variable. The chaos has been investigated with variable delay time and the synchronization phenomenon is examined both numerically and analytically using the Krasovskii-Lyapunov functions. We have applied adaptive coupling law for synchronization,where the coupling equation also contains delay with modulated time. We also studied the effect of cryptography for this coupled system and the message extraction procedure is illustrated with the help of simulated results.
