Asymmetric multiple-image encryption based on coupled logistic maps in fractional Fourier transform domain

Optics and Lasers in Engineering, 2014
Abstract A multiple-image encryption scheme is proposed based on the asymmetric technique, in which the encryption keys are not identical to the decryption ones. First, each plain image is scrambled based on a sequence of chaotic pairs generated with a system of two symmetrically coupled identical logistic maps.

Uncertainty principles for windowed coupled fractional Fourier transform

Mathematical Methods in the Applied Sciences
The windowed coupled fractional Fourier transform was recently proposed in the literature. It may be considered as a generalized version of the windowed fractional Fourier transform. In this study, we first present various basic properties of the windowed coupled fractional Fourier transform including linearity, shifting, modulation, parity ...
