Abstract

The synchronization based on active control strategy for different chaotic system is realized in order to solve the problem of sensitive dependence on initial conditions, and a square matrix for chaotic system states is also obtained by step-by-step operation of multi-elementary matrix transformation. Synchronous decryption of image can be realized because of the invertibility between decryption matrix and encryption matrix. The proposed dynamic encryption method based on chaotic synchronization has advantages of rapid encryption/decryption as well as high security, which also can be benefit to real-time transmission of image.
