Since the early 1990s, a large number of chaos-based communication systems have been
proposed exploiting the properties of chaotic waveforms. The motivation lies in the …

Because of the COVID-19 pandemic, most of the tasks have shifted to an online platform.
Sectors such as e-commerce, sensitive multi-media transfer, online banking have …

We show the usefulness of bifurcation diagrams to implement a pseudo-random number
generator (PRNG) based on chaotic maps. We provide details on the selection of the best …

A color image encryption algorithm using the Hénon-zigzag map and chaotic restricted
Boltzmann machine (CRBM) is proposed in this paper. The proposed pseudo-random …

Although chaotic systems with hidden attractors have been discovered recently, there is a
few investigations about relationships among them. In this work, we introduce a unique …

In this paper, by considering the Caputo-like delta difference definition, a fractional
difference order map with chaotic dynamics and with no equilibria is proposed. The complex …

An ultra-low power true random number generator (TRNG) based on a sub-ranging SAR
analog-to-digital converter (ADC) is proposed. The proposed TRNG is composed of a …

This paper presents a novel simple 4-D dissipative autonomous hyperchaotic system with a
saddle-point index-2 equilibrium point. The dynamics of the new system consists of nine …

This study investigates how qubits of modern quantum annealers (QA) such as D-Wave can
be applied for generating truly random numbers. We show how a QA can be initialised and …

Dynamic and non-linear systems have been used to generate random bits in high-security
applications for decades. In this perspective, due to their stochastic characteristic, chaotic …
