Dynamic Analysis of a Time-Delay Chaotic System and Its Application in Image Encryption
For a new chaos system with time delay,firstly,the stability analysis and Hopf bifurcation analysis of the equilibrium point of it are carried out in the paper,and numerical simulation shows that the change of time-delay near the time-delay-bifurcation point will affect the stability of the system.Secondly,the chaos system is applied to image encryption,the specific property of its sensitivity to ini-tial conditions is used to generate password,and then the purpose of transmitting the information encryption.Lastly,through simulation using the Matlab,focusing on the analysis of the encrypted histogram and the correlation between adjacent pixels,we find its good image encryption effect.
