像素值复合置乱的混沌图像加密方法
Chaotic image encryption method based on pixel value composite scrambling
摘要
Abstract
For most of chaotic image encryption methods, pixel is often seen as a whole unit to process in pixel value scrambling. It is very weak to resist known cleartext attack. Aiming at the problem, a high dimension chaotic encryption method based on discrete Hopfield feedback neural network is proposed. In the process of pixel value scrambling, each bit of pixel is the handle object. So the scrambling of each pixel value is a composite process. The validity of this method is verified through experimental results.关键词
