Testing the Strength of Chaotic Systems as Seeds in a Pseudo Random Bit Generator

IEEE Access
Chaotic random bit generators have become an integral part of chaotic cryptography and other data protection applications, where they are used as sources of deterministic randomness, to secure an information signal.

Applications of tripled chaotic maps in cryptography

, 2007
Security of information has become a major issue during the last decades. New algorithms based on chaotic maps were suggested for protection of different types of multimedia data, especially digital images and videos in this period. However, many of them

Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn2+‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

Advanced Science, EarlyView.
A multifunctional benzimidazole‐terminated CNF separator is constructed via a PEI‐mediated covalent locking strategy, generating dense zincophilic sites that accelerate Zn2+ transport and desolvation while enabling uniform Zn (002) deposition and suppressing side reactions.

Memristive Physical Reservoir Computing

Advanced Science, EarlyView.
Memristors’ nonlinear dynamics and input‐dependent memory effects make them ideal candidates for high‐performance physical reservoir computing (RC). Based on their conductance modulation, memristors can be classified as electronic or optoelectronic types.

Enhanced High Dimensionality and the Information Processing Capacity in Interfered Spin Wave‐Based Reservoir Computing, Achieved With Eight Detectors

Advanced Electronic Materials, EarlyView.
Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

CHAOTIC DIFFUSION IN MULTIDIMENSIONAL CONSERVATIVE MAPS

International Journal of Bifurcation and Chaos, 2012
In the present paper, we provide results and discussions concerning the processes that lead to local and global chaotic diffusion in the phase space of multidimensional conservative systems. We investigate and provide a measure of the extent of the domain over which diffusion may occur.
