Adaptive sliding mode observers in uncertain chaotic cryptosystems with a relaxed matching condition [PDF]

open access: yes, 2006
We study the performance of adaptive sliding mode observers in chaotic synchronization and communication in the presence of uncertainties. The proposed robust adaptive observer-based synchronization is used for cryptography based on chaotic masking ...

Pseudo-Random Number Generator Based on Logistic Chaotic System

open access: yesEntropy, 2019
In recent years, a chaotic system is considered as an important pseudo-random source to pseudo-random number generators (PRNGs). This paper proposes a PRNG based on a modified logistic chaotic system.

Chameleon Chaotic Systems With Quadratic Nonlinearities: An Adaptive Finite-Time Sliding Mode Control Approach and Circuit Simulation

open access: yesIEEE Access, 2021
A chameleon chaotic system is a chaotic system in which the chaotic attractor can change between hidden and self-excited attractor depending on the values of parameters.
