PCHET: An efficient programmable cellular automata based hybrid encryption technique for multi-chat client-server applications
This paper demonstrates an efficient programmable Cellular Automata (CA) based hybrid encryption technique (PCHET) for chatting applications involving multiple clients who can chat simultaneously with each other. The ...
Propuesta de mejora de un algoritmo criptográfico con la combinación de la esteganografía en imágenes

Experimental scrambling and noise reduction applied to the optical encryption of QR codes
(Optical Society Of America, 2014-08)
In this contribution, we implement two techniques to reinforce optical encryption, which we restrict in particular to the QR codes, but could be applied in a general encoding situation. To our knowledge, we present the ...
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 ...
Optimized random phase encryption
(Optical Society of America, 2018-08)
We propose for the first time, to the best of our knowledge, the use of optimized random phases (ORAPs) in a double random phase encryption scheme (DRPE). In DRPE schemes the convolution between two random phase functions ...
