| 摘 要： | 针对单向耦合超混沌Lorenz系统,通过引入坐标变换分析了投影同步的产生机理,同时研究了比例因子与耦合系统初值选取的关系.提出一种新颖的图像信息传输方案,理论与数值研究表明,此方案不仅能够实现对图像的无失真恢复,而且具有较高的安全性.

| Abstract: | The mechanism of projective synchronization for unidirectional coupled hyper-chaotic Lorenz system is analyzed by introducing coordinate transformation.And the relation between scale factors with initial conditions is investigated.A novel image information transmission plan is provided.Theoretical analysis and numerical simulation show the presented scheme not only can recover undistorted image but also has higher security. |
