An Image Encryption Technology Based on Chaotic Sequences and Fractional Fourier Transform

Presents an image encryption technology based on chaotic sequences and fractional Fourier transform.At first,the real number value chaotic sequences are generated by using the key value,then encrypt the image combining the method of image scrambling in space.Combing it and fractional Fourier transform,multichannel image encryption is implemented.The experimental results show that the technology is valid and has good security.
