Therefore the transmitted message is sensitive to the channel noise, and then the decoding message has a lower accuracy. A method of chaotic synchronization based on the linear stability criterion is utilized, and a technical scheme of chaotic masking for secure communication is proposed. A nonlinear drive vector function of special chaotic state variable is constructed by a proper separation of the linear and nonlinear terms in a chaotic system. The transmitted message is injected into one element of the state vector. Thus the scheme increases the complexity of masking message and the decoding difficulty. Lorenz attractor and Chen attractor are used as an example to simulate the application of sinusoidal information transmitted by chaotic masking technique. The configuration of the Jacobi matrix is flexible and multiple choices. A simple and optimal chaotic masking scheme is given through comparative analysis. Numerical analysis shows that even if the amplitude of sine function information for transmission is quite large, there is no effect on the decoding accuracy of the information. The proposed scheme is effective., authors=SONG Zhiping, YU Hongjie, authorsList=SONG Zhiping;YU Hongjie, authorCompany=Department of Engineering Mechanics, School of Naval Architecture, Ocean and

articleAbstract=混沌掩盖通信方案是最基础、最容易实施的保密通信方法,但要求传输信息的幅值要相当小,所以传输信息易受信道噪声影响,导致还原信息的解码精度降低.本文利用基于线性稳定性准则的混沌同步方法,提出一种进行信息保密通信的混沌掩盖方案.通过对混沌系统线性项与非线性项的适当分离,构造一个特殊的混沌状态变量的非线性驱动向量函数,将要传递的信息加入其中一个分量上,提高信息掩盖的复杂度和进行破解的困难度.以Lorenz吸引子和陈氏吸引子为例进行数值模拟,应用混沌掩盖技术传输正弦信息.雅克比矩阵的配置是灵活、多选的,文分析并给出简单、最优的混沌掩盖方案.数值分析证明,即使传输的正弦信息的振幅很大,也没有对解码信息的精度产生影响,同步效果很好.,
