This digital era uses lots of images in communication, which are confidential and large in
volume. The transmission channel thus arises the question of security as well as …

With the development of mobile communication network, especially 5G today and 6G in the
future, the security and privacy of digital images are important in network applications …

In this paper, we designed a new hyperchaotic two-dimensional map with wide distribution
and two large positive Lyapunov exponents. Then, we used it to construct a new randomized …

Over the last few years, lots of chaotic image encryption schemes have been proposed.
However, most of the schemes are permutation-diffusion architectures which still have some …

The performance of an image encryption algorithm based on chaos is largely determined by
the nonlinear characteristics of the underlying chaotic system. This paper proposes a mixed …

In this paper, a new two-dimensional discrete hyperchaotic system is proposed. Verification
using the phase-track map, bifurcation map and Lyapunov exponent of the chaotic system …

This letter proposes an image encryption algorithm using scrambling by exploiting the
features of chaotic maps suited for cryptography. The proposed algorithm performs …

In this paper, we propose an image encryption algorithm based on the memristive chaotic
system, elementary cellular automata (ECA) and compressive sensing (CS). Firstly, the …

Digital images can be large in size and contain sensitive information that needs protection.
Compression using compressed sensing performs well, but the measurement matrix directly …

Based on hyper-chaotic systems, a novel image encryption algorithm is introduced in this
paper. The advantages of our proposed approach are that it can be realized easily in one …
