Chaos-based cryptology has become one of the most common design techniques to design
new encryption algorithms in the last two decades. However, many proposals have been …

Privacy preservation has become a prerequisite for modern applications in the cloud, social
media, Internet of things (IoT), and E-healthcare systems. In general, health and medical …

Due to the potential security problem about key management and distribution for the
symmetric image encryption schemes, a novel asymmetric image encryption method is …

In the traditional image encryption systems, the permutation-diffusion operation is often
conducted in two essentially separable or independent steps, which appears not only to be …

Many researchers have used the properties of the popular Elliptic Curve Cryptography
(ECC) to devise a stronger and faster image encryption algorithm to assure the secrecy of …

In terms of Chua's circuit system, compressive sensing (CS) and Haar wavelet, a novel
image compression-encryption scheme (CES) is proposed in this paper. Firstly, the plaintext …

A novel and secure plaintext-related image encryption scheme is given in this paper using
hyper-chaotic Lorenz system and hash function. In our scheme, we used the classical …

In this paper, an image encryption program based on AES in cipher block chaining mode
was designed with C language. The encryption/decryption speed and security performance …

In this work, we propose a novel 3D chaotic map obtained by coupling the piecewise and
logistic maps. Showing excellent properties, like a high randomness, a high complexity and …

Chaotic image encryption is widely used in the field of information security. This paper
proposes a novel chaotic image encryption method with spiral-transform-based fractal …
