The Internet as the pioneer of the network is sweeping the globe, providing quick and inexpensive means of transmission for digital information products. Vivid image information is widely used for all of us, but it also brings safety problems. In order to protect the data owners' interests, also for personal privacy, copyright and other security reasons, a reliable encryption technology must be used in some image data.
Based on the ergodicity, mixed and index divergent characteristics of chaotic systems, this paper illustrates how the key sequence generated by chaotic system encrypts image and scrambles the encrypted result. This method is of very high safety and practicality. The simulation results also show that the method has good cryptographic properties.
