Optical image/data encryption techniques are mostly based on the manipulation of spatial
distributions of light's amplitude, phase, and polarization. Information encoding with phase …

In this paper, a noise-resistant image encryption scheme is proposed. We have used a cubic-
logistic map, Discrete Wavelet Transform (DWT), and bit-plane extraction method to encrypt …

Optical cryptosystems mostly use spatial distributions of amplitude, phase, and polarization
of light to encrypt two-dimensional data/image. In this letter, we demonstrate the use of light …

The security of the data becomes the main concern due to the quick rise in the exchange of
data over the open networks and the Internet. The cryptographic techniques based on chaos …

This paper proposes a new color image encryption system based on compressed sensing
and multi-image cross pixel scrambling approach. In the encryption process, firstly, the color …

We propose an asymmetric image encryption scheme that employs chaotic phase masks
and vectorial light field. Vector light fields have non-uniform state of polarization across the …

Features of vector beam such as its spatial degree of freedom and intensity-based
measurements are useful in information encoding but often require a complex optical-setup …

Holographic encryption has obvious advantages in large key space and anti-attack ability,
but the corresponding coherent noise and optical alignment requirement greatly affect the …

Vector light fields have spatially non-uniform polarization across the transverse plane. In this
study, a color image encryption scheme has been proposed in which the data is encoded …

Optical vortices have gained considerable attention as they offer high-dimensional encoding
owing to their mode orthogonality. This paper demonstrates two-dimensional exclusive-OR …
