Abstract
An image encryption algorithm based on chaotic sequences is that the chaotic mapping parameter is changed randomly by m-sequence, and nonlinear m-sequence perturbation is introduced in output of chaotic function and encrypt image. After chaotic time signal and parameter was changed randomly, and the chaotic mapping of perturbation and encryption algorithm was added, the image was processed and identified by distinguishing scenery outline and scenery, and background gradation. Image encryption was simulated with computer, and the result shows that image encryption algorithm can satisfy encryption request.
