Image Scrambling Encryption by Mix Fan Transform matrixes technology

In this paper, we enhance the security by making use of the diversity of FAN Transform, and scrambling the image with different transform matrixes, furthermore, an improved Max Fan image scrambling transformation is introduced in this paper. Meanwhile, we also introduce a conservation method of MIX FAN Secure Key which facilitates the management of the complicated secure keys. Mix Fan increases the decoding difficulties, and enhances the security. This paper mainly explains the principles of MIX FAN, and the practicability of MIX FAN was tested by computer.
