Image Encryption Method Based on Image Dimension Transformation Using Chaotic Flow systems
(Universidad del Zulia, 2019)
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Asymmetric multiple-image encryption system based on a chirp z-transform
(Optical Society of America, 2019-07)
An asymmetric multi-image encryption system based on the chirp z-transform (CZT) is demonstrated. The setup is a hybrid architecture that combines a double-random-phase encryption scheme in 4f configuration and a multiplexing ...
Joint transform correlator optical encryption system: Extensions of the recorded encrypted signal and its inverse Fourier transform
(Elsevier Science, 2015-05)
In this work we study the joint transform correlator setup, finding two analytical expressions for the extensions of the joint power spectrum and its inverse Fourier transform. We found that an optimum efficiency is reached, ...
Galois Ring GR (2(3),8) Dependent 24 x 24 S-Box Design: An RGB Image Encryption Application
(Springer, 2020-04-19)
An S-box is based on Boolean functions which are essentially the foundation of symmetric cryptographic systems. The Boolean functions are used for S-box designing in block ciphers and exploited as nonlinear components. ...
