A New Image Encryption Algorithm Based on Modified Optically Injected Semiconductor Laser Chaotic System

open access: yesIEEE Access, 2021
Compared with general chaotic systems, laser chaotic systems have more complex dynamic behaviors and extremely high sensitivity to parameters and initial values.

On systems of maximal quantum chaos

open access: yesJournal of High Energy Physics, 2021
A remarkable feature of chaos in many-body quantum systems is the existence of a bound on the quantum Lyapunov exponent. An important question is to understand what is special about maximally chaotic systems which saturate this bound.

A Class of Quadratic Polynomial Chaotic Maps and Their Fixed Points Analysis

open access: yesEntropy, 2019
When chaotic systems are used in different practical applications, such as chaotic secure communication and chaotic pseudorandom sequence generators, a large number of chaotic systems are strongly required.

Nonchaotic Behavior and Transition to Chaos in Lorenz-like Systems Having Invariant Algebraic Surfaces

open access: yesChaos Theory and Applications, 2022
The famous and well-studied Lorenz system is considered a paradigm for chaotic behavior in three-dimensional continuous differential systems. After the appearance of such a system in 1963, several Lorenz-like chaotic systems have been proposed and ...

Discrete-time synchronization of chaotic systems for secure communication [PDF]

open access: yes, 2012
This paper deals with the problem of designing an exact nonlinear reconstructor for discrete-time chaotic encrypted messages. More precisely, we investigate the problem of designing a discrete-time dead-beat observer for nonlinear systems with unknown ...

The importance of choosing attractors for optimizing chaotic communications [PDF]

open access: yes, 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.

Digitization of chaotic signal for reliable communication in non-ideal channels [PDF]

open access: yes, 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.
