Because digital image has its inherent characteristics, traditional encryption algorithms don't very well adapt to digital image encryption. In light of the structural characteristic of color digital image, according to the encrypting principle of digital image scrambling, and using the characteristics of discrete chaotic sequence, such as randominess, extreme sensitivity to initial condition values, and so on, both the encryption and decryption of color digital image are studied. Research results have shown that this kind of encryption and decryption of image is not only simple and fast in image encryption and decryption, but also satisfies the security requirement for image transmission and storage.
