摘要
提出了一种利用小波包分析算法将图像信息进行分解 ,然后采用混沌猫映射的思想进行加密的图像加密方法。该方法可成功地应用于多媒体信息加密技术。实验表明 ,此算法简单 ,系统鲁棒性好 ,加密效果佳。
A new image encryption is presented.With the wa velet package analysis,the image is decompounded.Then it is encrypted by the cat mapping.This algorithm can apply for the multimedia datahiding t echnique succesfully.The simulation results can confirm that the algorithm can b e realized simply,has preferable robustness and the effect of image cncryption.
