Image encryption techniques play a significant role in multimedia applications to secure and
authenticate digital images. This paper presents a comprehensive study of various image …

Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

Recently, a number of chaos-based image encryption algorithms have been proposed at the
pixel level, but little research at the bit level has been conducted. This paper presents a …

In this paper, a new chaotic color image encryption algorithm is proposed. This algorithm
uses a composite chaotic map combined with a staged Logistic map and Tent map for initial …

Images contain very sensitive and confidential information. Because images play a
significant role in many applications such as military communication, remote‐sensing, and …

This research proposes a new image encryption scheme based on Lorenz hyperchaotic
system and Rivest–Shamir–Adleman (RSA) algorithm. Firstly, the initial values of the Lorenz …

Because quantum computing can break encryption systems based on mathematical models,
this paper proposes a new color quantum image encryption algorithm based on …

In this paper, an optical color image encryption scheme based on fingerprint key and three-
step phase-shifting digital holography is proposed. In the proposed encryption scheme, the …

An optical single-channel color image encryption scheme based on chaotic fingerprint
phase mask and diffractive imaging is proposed. In this proposed encryption scheme, the …

A single channel optical asymmetric cryptosystem for color image in fractional Fourier
transform (FrFT) domain is presented. Instead of commonly used RGB channels encryption …
