Image Encryption Based on Function Expansion and Hyperchaotic System
为有效保护数字图像的安全,提出一种基于小波展开函数与超混沌系统的数字图像加密算法.利用小波展开函数对网像进行置乱,通过超混沌系统扰乱原图像与加密图像之间的关系.在求解超混沌系统混沌序列的四阶Runge-Kutta公式中,插入多个参数以扩大参数空间.模拟实验结果表明,加密后图像灰度值分布伪随机性较好.
In order to protect the security of a digital image effectively, this paper proposes an image encryption algorithm based on wavelet expansion function and hyperchaotic system. The pixel locations of the image are scrambled with a wavelet function, and the relationship between the original image and the encrypted image is disrupted with hyper-chaos system. The many parameters are inserted in four-step Runge-Kutta method in which chaos sequence of hyper--chaos…查看全部>>
