permute

we wish to permute the order of the bytes.

我们希望改变字节的顺序。

The algorithm in the proposed program can mask the image data and permute pixels location by chaotic sequences.

算法程序首次采用图像据的混沌掩盖加和图像象素位置的置乱加相结合的方法,对图像进行两次复合的混沌加。

Image array disturbed algorithm has been improved to implement multiple permute better.The algorithm shortens its encryption time, so it fits image encryption well.

更好的实现多步置乱,对图像位置置乱算法进行改进,改进后的算法提升混沌位置置乱加速度,符合图像加的需要。
