Digital Cosine Chaotic Map for Cryptographic Applications
IEEE Access, 2019 Despite having many similar characteristics with cryptography, existing chaotic systems have many security issues that negatively affect the chaos-based cryptographic algorithms that utilize them.

The importance of choosing attractors for optimizing chaotic communications [PDF]
, 2004 In this brief, we consider methods to improve the performance of chaotic communication schemes. We study a system using a receiver which explicitly includes the presence of noise in the channel.

Abrupt bifurcations in chaotic scattering : view from the anti-integrable limit [PDF]
, 2013 Bleher, Ott and Grebogi found numerically an interesting chaotic phenomenon in 1989 for the scattering of a particle in a plane from a potential field with several peaks of equal height.

IEEE Access, 2022 We present a general framework for improving the chaotic properties of CMOS-based chaotic maps by cascading multiple maps in series. Along with two novel chaotic map topologies, we present the 45 $nm$ designs for four CMOS-based discrete-time chaotic ...

A Double-Layer Image Encryption Scheme Based on Chaotic Maps and DNA Strand Displacement
Journal of Chemistry, 2022 The image encryption schemes combining chaotic maps, DNA coding, and DNA sequence operation can effectively protect the image. In this paper, a double-layer image encryption scheme is proposed by combining chaotic maps with DNA strand displacement (DSD).

Digitization of chaotic signal for reliable communication in non-ideal channels [PDF]
, 2008 A new method of chaotic communication system based on digitization of the chaotic signal is proposed. The digitally encoded chaotic signal is transmitted through a practical channel and recovered at the receiver.

An investigation of the effects of chaotic maps on the performance of metaheuristics
Engineering Reports, 2021 This article presents an empirical investigation of the effects of chaotic maps on the performance of metaheuristics. Particle Swarm Optimization and Simulated Annealing are modified to use chaotic maps instead of the traditional pseudorandom number ...

Random Delays and the Synchronization of Chaotic Maps [PDF]
Physical Review Letters, 2005 We investigate the dynamics of an array of logistic maps coupled with random delay times. We report that for adequate coupling strength the array is able to synchronize, in spite of the random delays. Specifically, we find that the synchronized state is a homogeneous steady-state, where the chaotic dynamics of the individual maps is suppressed.

Algebraic entropy for algebraic maps [PDF]
, 2015 We propose an extension of the concept of algebraic entropy, as introduced by Bellon and Viallet for rational maps, to algebraic maps (or correspondences) of a certain kind. The corresponding entropy is an index of the complexity of the map.
