In this paper we review a number of optical image encryption techniques proposed in the
literature inspired by the architecture of the classic optical Double Random Phase Encoding …

Over the years extensive studies have been carried out to apply coherent optics methods in
real-time communications and image transmission. This is especially true when a large …

We demonstrate a method of chosen-plaintext attack on lensless double-random phase
encoding (L-DRPE) in the Fresnel domain. With this attack an opponent can access two …

Several attacks are proposed against the double random phase encryption scheme. These
attacks are demonstrated on computer-generated ciphered images. The scheme is shown to …

The applications of compressive sensing (CS) in the field of information security have
captured a great deal of researchers' attention in the past decade. To supply guidance for …

We analyze the security of a recently proposed asymmetric cryptosystem that based on the
phase-truncated Fourier transforms (PTFTs), and describe a specific attack method to break …

Optical cryptanalysis is essential to the further investigation of more secure optical
cryptosystems. Learning-based attack of optical encryption eliminates the need for the …

An optical color image encryption method based on Hadamard single-pixel imaging (SPI)
and Arnold transformation is proposed, in which, optical full-color image encryption with …

A novel asymmetric cryptosystem based on coherent superposition, which is free from
silhouette problem, is proposed. Being different from the phase-truncated Fourier transform …

In this paper, we propose a novel optical asymmetric fingerprint image encryption technique
that uses QR decomposition in gyrator wavelet transform domain. A fingerprint image is …
