“…It is with great achievement to note that this research paper considers the WBC with conventional parameters coupled to the RCSJJ model which remain not yet been investigated and the interest in coupling both systems with separate rich behaviors is to obtain complex characteristics like chaos which find wide application in security regarding encryption of sEMG signals [46,47], communication [48] and network [49,50]. This paper then further realized the interesting application of security with the success reported in encrypting a biomedical image.…”

This paper recounts the dynamical investigations and microcontroller validation of Josephson junction (JJ) driven by Wien bridge circuit (WBC). Relying on the stability analysis of two equilibrium points found in JJ driven by WBC (JJDWBC), it is revealed that one equilibrium point is unconditionally stable while the other equilibrium point is unstable. The JJDWBC exhibits reverse period-doubling bifurcation, periodic attractors, period-doubling bifurcation, bistable chaotic attractors, and different presentations of monostable chaotic attractors. Partial and total amplitude controls are achieved by adding two controller parameters into the rate equations of JJDWBC. Finally, the microcontroller implementation is used to validate the dynamical behaviors found in JJDWBC.

“…The method for protecting digital photographs is called picture encryption generation [9][10][11][12][13], and its fundamental idea is to encrypt the digital records that are contained within the digital photograph, as well as to acquire the completely exceptional encrypted photographs of the appearance and the genuine digital photograph. This ensures that the content of the digital photograph can't be viewed immediately.…”

In every form of electronic communication, data security must be an absolute top priority. As the prevalence of Internet and other forms of electronic communication continues to expand, so too does the need for visual content. There are numerous options for protecting transmitted data. It's important that the transmission of hidden messages in images remain unnoticed to avoid raising any red flags. In this paper, we propose a new deep learning-based image encryption algorithm for safe image retrieval. The proposed algorithm employs a deep artificial neural network model to extract features via sample training, allowing for more secure image network transmission. The algorithm is incorporated into a deep learning-based image retrieval process with Convolution Neural Networks(CNN), improving the efficiency of retrieval while also guaranteeing the security of ciphertext images. Experiments conducted on five different datasets demonstrate that the proposed algorithm vastly improves retrieval efficiency and strengthens data security. Also hypothesised a 2D Sin-Cos-Henon (2D-SCH)-based encryption algorithm for highly secure colour images. We demonstrate that this algorithm is secure against a variety of attacks and that it can encrypt all three colour channels of an image simultaneously.

“…In some considerations, the crisis mechanism in the non-linear damp JJ for the appearance of complex characteristics was exploited [3]. Chaotic, bursting, and spiking behaviors were investigated in JJ with nonlinear resistance [38,39], Field-Programmable Gate Array (FPGA) validation and encryption mechanisms in the piecewise JJ [40], coding of Surface Electromyography (sEMG) signal with nonlinear resistance JJ model [41], and recently, the protection of a medical picture with the self-driving piecewise damp JJ jerk oscillator by Ramadoss et al [30].…”

This paper evaluates the microcontroller implementation, offset boosting control, suppression of chaos, and combination of three types of synchronization in the autonomous piecewise damping Josephson junction (JJ) jerk oscillator (APDJJJO). The APDJJJO exhibits vast shapes of chaotic behaviors, bistable limit circles, bistable period-2-oscillation, and the coexistence of regular and chaotic behaviors exposed by numerical simulations. The microcontroller realization scheme of APDJJJO validates simulated dynamics. Proceeding, two constants are outlined in the rate equations of APDJJJO to achieve the linear offset boosting of constants based on the second and third state variables, respectively. The polarity of the chaotic signal of the second or third state variable can be flexibly altered by changing any of the two introduced constants while the other constant is kept at zero. When the two constants are equal, the second and third state variables can swap between bipolar and unipolar signals flexibly by altering the unique constant parameter. Moreover, theoretical probing is performed to validate the efficacy of the configured single controller engrossed in subduing chaos in APDJJJO. Lastly, the combination of three types of synchronization between two chaotic APDJJJO are analytically and numerically investigated.
