This paper presents a confidential algorithm based on gray image diffusion of Cai Shaotang system. Cai Shaotang chaos system research, the system simulation analysis, bifurcation analysis, research with the change of parameters of process system. Image encryption, chaotic sequence is generated by the Cai Shaotang system, and then to optimize the sequence of diffusion, the ranks of encryption. Image encryption algorithm security, through correlation analysis, information entropy analysis can prove that. This algorithm can greatly improve the security of digital image, to ensure the safety of the transmission of digital images.
