Using the characteristics of the chaotic system, such as ergodicity, sensitivity to initial condition, system parameters and random like behavior, this paper proposes a new image encryption algorithm based on chaotic sequences and wavelet transform. This algorithm controls the initial parameters of two one-dimensional chaotic sequences through keys, generates the chaotic sequence, diffuses the image,...
This paper puts forward a new color image encryption method. Since the logistic map does not satisfy consistent distribution, an improved logistic map is proposed, which has a better random distribution than the general logistic map. Firstly, the improved logistic map is used to confuse the color image, and then diffuse the confused image with a four-dimensional hyper-chaotic sequence. In the diffusion...
As the connection between transmission network and consumers facilities, distribution network has been paid more and more attentions about its planning.A scientific and efficient optimization project for distribution network structure can save investment,reduce power-cutting and the line losses, as well as improve the quality of electric power,which is currently one of the important task of the departments...
