| 摘 要： | 将离散混沌系统Dead-Beat同步方法应用于超混沌广义Henon映射,提出一种离散超混沌同步加密方案。该方案应用高复杂度的超混沌信号以增强载波信号的随机性,并利用了广义Henon映射Dead-Beat同步加密的复杂性。仿真结果显示:密文加密效果好,恢复图像与原图像差别很小。

| Abstract: | In this paper,the technologies of the discrete-time chaotic system's Dead-Beat synchronization are used in the chaotic generalized Henon map and a discrete-time hyperchaotic synchronization encrypted method is developed.The hyperchaotic signal is used to enhance the randomness of carrier and the complexity of generalized Henon map Dead-Beat synchronization encryption is used.The simulation shows that the ciphertext's encryption effect is well,and the recovered image is less different with the original image. |
