Secure communication with a chaotic system owning logic element

Synthetic Adaptive Fuzzy Disturbance Observer and Sliding-Mode Control for Chaos-Based Secure Communication Systems

“…Their paper introduced the H-infinity combined with sum-of-squares to synchronize and effectively reject disturbances. Çiçek et al [2] proposed a new logic element chaotic system to provide a secure communication system background. Their sliding-mode control is an important portion of the synchronization algorithm.…”

“…Two experimental cases of the proposed approach were well performed on computers with electronic circuit synchronization [23]. In previous papers [2][3] and [49] there are no disturbance observers for the synchronization, which leads the performance of the real experiment synchronization system to go awry. In [2] the sliding-mode control was proposed for synchronizing a chaotic logic system without the existence of disturbance.…”

A Novel Chaotic System with a Line Equilibrium: Analysis and Its Applications to Secure Communication and Random Bit Generation

“…In this section, the proposed chaotic system is applied to the problem of secure communications. The methodology considered is the symmetric chaos shift keying (SCSK) modulation, which was applied in [7,28]; see also [27,[33][34][35][36][37][38][39] for similar approaches. The system design is shown in Figure 9.…”

Disturbance and Uncertainty Rejection-Based on Fixed-Time Sliding-Mode Control for the Secure Communication of Chaotic Systems

“…In [2], the secure communication of two nonidentical logic circuits was archived with the support of a sliding-mode control (SMC) method. The paper ignored that, when a circuit is implemented in an experiment, changes in the mainboard uncertainties, capacitors, and resistors always occur.…”

“…The precision of the recovery data depends on the precision of synchronization control. Some motivations from previous published papers are as follows: In [2], an SMC was used to synchronize the master and slave of a logical element chaotic system, and the synchronization outcome was good under ideal conditions. However, the synchronization overshoot and settling times were still high.…”
