Synchronization and partial synchronization of linear maps

, 2003
We study synchronization of low-dimensional ($d=2,3,4$) chaotic piecewise linear maps. For Bernoulli maps we find Lyapunov exponents and locate the synchronization transition, that numerically is found to be discontinuous (despite continuously vanishing ...

A Secure Anonymous Identity-Based Virtual-Space Agreement Method for Crowds-Based Anonymous Communicate Scheme

IET Information Security, 2023
Anonymous data exchange is in great demand in many situations, especially in remote control systems, in which a stable, secure, and secret data channel must be established between the controlling and controlled parties to distribute control commands and ...

Nonlinearly driven transverse synchronization in coupled chaotic systems

, 2005
Synchronization transitions are investigated in coupled chaotic maps. Depending on the relative weight of linear versus nonlinear instability mechanisms associated to the single map two different scenarios for the transition may occur. When only two maps

An Extended Chaotic Map-Based Authentication and Key Agreement Scheme for Multi-Server Environment

Mathematics, 2021
With the increasing number of users and the emergence of different types of network services, a multi-server architecture has emerged in recent years. In order to ensure the secure communication of Internet participants in an open network environment, the authentication and key agreement protocol for multi-server architectures were proposed in the past.

Information transfer and nontrivial collective behavior in chaotic coupled map networks

, 2002
The emergence of nontrivial collective behavior in networks of coupled chaotic maps is investigated by means of a nonlinear mutual prediction method. The resulting prediction error is used to measure the amount of information that a local unit possesses ...

A-coupled-expanding and distributional chaos [PDF]

, 2014
The concept of A-coupled-expanding map, which is one of the more natural and useful ideas generalized the horseshoe map, is well known as a criterion of chaos. It is well known that distributional chaos is one of the concepts which reflect strong chaotic

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.
