Improved decryption quality with a random reference beam cryptosystem
(Elsevier, 2019-01)
The secure managing of sensible data is one of the main challenges nowadays. During the last years several advances have demonstrated the ability of optical encrypting systems to protect information. In spite of these ...
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, ...
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 ...
