This work presents a simple method of designing pseudo-random bit generator by generating multiple bits per iteration from the decimal part of a chaotic map. This is done by extracting the decimal part of the state in each iteration and comparing eac

In the current study, we investigate the possibility of constructing sensors based on chaotic circuits with memristors. The study involves different memristor models, both simple and more physically realistic. We demonstrate that changes in the induc

Information security plays an important role in modern technologies. Stream encryption is one of the common tools used for secure communications. The stream encryption algorithms require sequence with pseudo-random properties. The chaotic maps as a s

Semi-implicit multistep methods are an efficient tool for solving large-scale ODE systems. This recently emerged technique is based on modified Adams–Bashforth–Moulton (ABM) methods. In this paper, we introduce new semi-explicit and semi-implicit

Dynamical degradation is a known problem in the computer simulation of chaotic systems. Data type limitations, sampling, and rounding errors give rise to the periodic behavior. In applications of chaotic systems in secure communication and cryptograp

The increasing complexity of advanced devices and systems increases the scale of mathematical models used in computer simulations. Multiparametric analysis and study on long-term time intervals of large-scale systems are computationally expensive. Th

The synchronization between chaotic systems implemented in similar ways—e.g., computer models or circuits—is a well-investigated topic. Nevertheless, in many practical applications, such as communication, identification, machine sensing, etc., sy

Multistep integration methods are widespread in the simulation of high-dimensional dynamical systems due to their low computational costs. However, the stability of these methods decreases with the increase of the accuracy order, so there is a known

This work proposes a modified logistic map based on the system previously proposed by Han in 2019. The constructed map exhibits interesting chaos related phenomena like antimonotonicity, crisis, and coexisting attractors. In addition, the Lyapunov ex
