An image encryption algorithm based on double scrambling
Min Lian-quan · Cehui kexue · 2006
Image scrambling is an effective method for image encryption,its effect depends on scrambling matrix.The paper discusses the characteristics of chaotic sequence,and generates position matrix and gray matrix using of its sensitivity to initial condition.Then combination of these two matrixes is used to encrypt image.The experimental results show that the algorithm is fairly good in efficiency and security.
