This paper put forward an image encryption algorithm based on the parameters of chaos control for permutation-diffusion structure.In this algorithm,Tent-Logistic map is used to generate permutation phase of the control parameters,analyze high correlation between shuffle image and permutation image pixels.In the diffusion stage,Tent-Logistic map for different initial conditions and control parameters generate initial state of Hopfield chaotic neural network,iterate that neural network,and generate the key stream for diffusion stage.Algorithm simulation experiment and numerical statistics analysis shows that the algorithm has good performance against the attack,reach the corresponding safety level.
