Image Encryption Method Based on Chaotic Map

摘要：

The combination of the chaotic theory and the cryptography is an important study field of the image encryption. Classical Arnold cat map can change the position of image pixel points through iteration, but these pixel points will return to the original position after iterating many times. It is obvious not enough to carry on the encryption by using it only. If the encrypted result with cat map is carried to Lu chaotic map to encrypt again, it can attain the purpose of confusion and diffusion through changing the pixel value of each point. The system security lies in the initial sensitivity of chaotic map. By using the Matlab to simulate, comparing with the encryption of single map, the method has the high improvement in anti-attacking.
