Min Long · Jisuanji gongcheng · 2005
The paper proposed an image encryption algorithm based on mixed chaotic dynamic systems including Lorenz system, Chen system and Lu system. With the map of the external keys, the initial condition of the mixed dynamic systems was acquired and chaotic signals were generated subsequently, then the plain image was encrypted by masking with the chaotic signals. The simulation and analysis results show that the chaotic signals are greatly sensitive to the keys and the algorithm has a large space of keys to acquire good encryption effects and efficiency, and a better security performance to statistical analysis.
