Journal ArticleDOI
Image encryption based on interference that uses fractional Fourier domain asymmetric keys
TL;DR: An image encryption technique based on the interference principle and phase-truncation approach in the fractional Fourier domain that offers multiple levels of security with asymmetric keys and is free from the silhouette problem.
Journal ArticleDOI
Fresnel domain nonlinear optical image encryption scheme based on Gerchberg–Saxton phase-retrieval algorithm
TL;DR: The cryptanalysis has been carried out, which proves the robustness of proposed scheme against known-plaintext, chosen-plain text, and special attacks, and a simple optical setup for decryption has been suggested.
Journal ArticleDOI
Known-plaintext attack-based optical cryptosystem using phase-truncated Fresnel transform
TL;DR: A scheme for information security under the basic double random phase encoding framework but with enhanced complexity and immunity against the known-plaintext attack, and presents the computer simulation results of multiple gray-scale images without any cross talk and also for a color image.
Journal ArticleDOI
Asymmetric color cryptosystem using polarization selective diffractive optical element and structured phase mask
TL;DR: A single channel asymmetric color image encryption scheme is proposed that uses an amplitude- and phase- truncation approach with interference of polarized wavefronts to alleviate the alignment problem of interference and does not need iterative encoding and offers multiple levels of security.
Journal ArticleDOI
Image encryption using polarized light encoding and amplitude and phase truncation in the Fresnel domain
TL;DR: An image encryption scheme based on polarized light encoding and a phase-truncation approach in the Fresnel transform domain and offers several advantages, including a lens-free setup, flexibility in the encryption key design, use of asymmetric keys, and immunity against special attack.
