Optical and digital double color-image encryption algorithm using 3D chaotic map and 2D-multiple parameter fractional discrete cosine transform

This paper proposes a new encryption and decryption method for optical and digital double color-images using 2D-multiple parameter fractional discrete cosine transform (MPFrDCT) and 3D-logistic chaotic map (3D-LCM). The double color-images to be encrypted are converted to their indexed formats by ex...
