Huang Xiaosu · Jisuanji gongcheng · 2006
This paper presents a new image encryption scheme based on generalized synchronization chaotic systems and Hash functions.The new scheme implements the image encryption by means of twice iterations based on confusion matrix and transformation sequences generated by sampling chaotic signals and Hash functions.As a direct application of the scheme,Chen’s GSCS is studied in som detail.Theoretical analysis and experimental results demonstrate that the cipher-image is sensitive to initial conditions of chaotic system and original image,the key space is great.So the scheme is of favorable and reliable for secure communication.
