A Proposal of a New Chaotic Map for Application in the Image Encryption Domain
, 2023 Several chaos-based image encryption schemes have been proposed in the last decade. Each encryption scheme has pros and cons regarding its speed, complexity, and security.

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.

Stochastic webs and quantum transport in superlattices : an introductory review. [PDF]
, 2009 Stochastic webs were discovered, first by Arnold for multi-dimensional Hamiltonian systems, and later byChernikov et al. for the low-dimensional case. Generated by weak perturbations, they consist of thread-like regions of chaotic dynamics in phase space.

Construction of a New Discrete Chaotic Mapping Based on the Robust Chaos Theorem
MathematicsChaotic systems serve as fundamental pseudo-random sequence generators in encryption algorithms and play a vital role in communication security. However, most current research still focus on the classical Logistic chaotic map, making it vulnerable to ...

LP-Conjugation: Unraveling Time Series Dynamics through Chaotic Map Convolution
, 2023 LP-Conjugation, introduced by Padua and Libao, is a versatile method used in solving the Inverse Frobenius-Perron problem (IFPP) for chaotic systems based on time series data.

ESTIMATING HYPERBOLICITY OF CHAOTIC BIDIMENSIONAL MAPS [PDF]
International Journal of Bifurcation and Chaos, 2012 We apply to bidimensional chaotic maps the numerical method proposed by Ginelli et al. [2007] to approximate the associated Oseledets splitting, i.e. the set of linear subspaces spanned by the so-called covariant Lyapunov vectors (CLV) and corresponding to the Lyapunov spectrum.

BER Performance Improvement of Dual Chaotic Maps Based on STBC Communication System
Al-Khawarizmi Engineering Journal, 2022 Sensitive information of any multimedia must be encrypted before transmission. The dual chaotic algorithm is a good option to encrypt sensitive information by using different parameters and different initial conditions for two chaotic maps.

A new approach to the treatment of separatrix chaos [PDF]
, 2012 We review an approach to separatrix chaos that has allowed us to solve some significant problems by: (i) finding analytically the maximum width of the chaotic layer, a problem that lay unsolved for 40 years, and showing that the maximum may be much ...
