ABSTRACT
ABSTRACT: Based on the fractional-order generalized augmented Lü system, a kind of double encryption algorithm method is designed to realize image encryption. The method mainly refers to the scramble of the pixel position and the transformation of the pixel value. The effectiveness of the double encryption method is verified by encrypting and decrypting the image. The experimental results indicate that this method not only has a better effect of image encryption and decryption, but also ensures the security of the encrypted image. The results from the histogram analysis and correlation analysis also verify the security and effectiveness of the proposed encryption method.
