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. ...
Cryptographic salting for security enhancement of double random phase encryption schemes
(Institute of Physics Publishing, 2017-09)
Security in optical encryption techniques is a subject of great importance, especially in light of recent reports of successful attacks. We propose a new procedure to reinforce the ciphertexts generated in double random ...
The space-bandwidth product in the joint transform correlator optical encryption setup
(Elsevier Science, 2011-09-01)
In this work we study the joint transform correlator (JTC) optical encryption setup through the Wigner function. We found analytical expressions for the spatial and spatial frequency extent of the encrypted signal. Since ...
Experimental optical encryption of grayscale information
(OSA - The Optical Society, 2017-07)
In this paper, we present a new protocol for achieving lower noise and consequently a higher dynamic range in optical encryption. This protocol allows for the securing and optimal recovery of any arbitrary grayscale images ...
