The security of images has become a hot research area due to the widespread usage of the digital images all over the world. Literature review on chaotic image cryptography, on the other hand, indicates that many constructs have been employed for the realization of confusion operation while developing the image ciphers. To enhance the computational time, this study proposes a novel image cipher based on two chaotic maps and rectangle as a scrambler. As the given grayscale image is input, it is scrambled through dynamically generated rectangles. As a modus operandi, these rectangles are created in the given image with various dimensions and different location. The pixels lying on the boundary of the rectangle are rotated clockwise and anticlockwise with an arbitrary amount. These operations have been repeated a number of times to get the scrambling effects. The scrambled image has been further subjected to an XOR operation for embedding the diffusion effects in it. Two chaotic maps of Hénon and piecewise linear chaotic map have been used for the generation of random numbers. These numbers help in deciding the size, location, clockwise/anticlockwise movement of the pixels and the amount with which these pixels have to be rotated. The performance analysis and the machine simulation validate that the suggested cipher is sufficient enough to thwart the varied cryptanalytic attacks. In particular, we gained the computational speed of 0.5156 seconds and the information entropy of 7.9975. Besides, we posit that it has the ample prospects for its real world application.

“…Additionally, many synchronization schemes for memristive system have been studied, such as finite-time quantized synchronization method was studied in [14], UDE-based complete synchronization and antisynchronization method was proposed in [15], switching SMC combina tion synchronization and parameter identification method was considered in [16], finite-time H ∞ synchronization method was described in [17], adaptive fuzzy-impulsive synchronization method was focused in [18], active projective synchronization method was described in [19], passive-constrained synchronization control method was given in [20], inverse matrix projective difference synchronization method and its application were investigated in [21], and other synchronization control schemes were described in [22][23][24][25][26]. An image encryption method employing memristive map was introduced in [27]. Adaptive symmetry control in security systems was realized in [28].…”

The subject of this article is to study a memristive system and modulation and demodulate the information signal in security system, a novel memristive system is presented and its dynamics are considered. Then, the adaptive synchronization control between the proposed memristive systems is demonstrated. Additionally, the original signal is modulated in a system parameter and it can be demodulated by using filter technology. Compared to previous secure systems, in this scheme, the demodulated signal can be adjusted by the adaptive filter, It has better security performance and is easy to implement in engineering.
