一种基于混沌渐近同步的数字保密通信方法

A method of digital secure communication based on asymptotic synchronization of chaos

根据驱动-响应混沌同步原理,提出了一种基于混沌渐近同步的数字保密通信方法。通过设计对发射信号进行多级单值非线性变换,使得通过预测法的攻击完全失效,因而这种通信方法具有较高的抗破译能力。理论分析和数值模拟结果证实了本方法的正确性与有效性。

Based on the theory of chaotic synchronization of driving-response, a method of digital secure communication using asymptotic chaotic synchronization is proposed. It is impossible to attack by a deterministic technical by designing multilevel nonlinear transformation for the transmitted signal. So this secure communication method has advantage of property of high resistant decryption. Theoretical analysis and numerical simulation results show that this secure communication method is correct and effective.
