基于互联网的超混沌图像加密

A Chaotic Image Encrypted Approach Based on Hyperchaos

超混沌信号复杂度高,可以增加载波信号的随机性以及不可预测性。提出了采用超混沌信号对图像信号所进行的混沌掩盖的加密方法以及在此基础上所进行的超混沌复合加密方法,仿真结果显示:密文加密效果好,恢复图像与原图像一致。

In this paper an encrypted method using hyperchaotic signal masking image signal and based on it an hyperchaotic complex e ncrypted method are developed.The h yperchaotic signal' s high com-plexity,high randomicity and nonfo recast are used.The simulation show s that the ciphertext' s encryption effect is well and the recovered imag e is consistent with original image.
