Many drawbacks in chaos-based applications emerge from the chaotic maps' poor dynamic properties. To address this problem, in this paper a chaotification model based on modulo operator and secant functions to augment the dynamic properties of existing chaotic maps is proposed. It is demonstrated tha ...

This paper investigates the issue of chaos-based image encryption. Based on the z-shaped fuzzy number, the exponential function, and
the modulo operator, a 1-D chaotic map is constructed and studied. This map contains areas with constant chaotic behavior and high
Lyapunov exponent values. A statis ...

In the research on chaotic systems, which are used for cryptography and secure communication schemes, a key characteristic is the introduction of novel chaotic systems, usually by adding complexity to the existing ones in order to ensure security. In this direction, this chapter proposes novel chaot ...

This paper investigates the issue of chaos-based image encryption. A new one-dimensional piecewise chaotic map based on the z-shaped fuzzy number is proposed and investigated, exhibiting regions of constant chaos and high Lyapunov exponent values. A pseudorandom bit generator based on the novel chao ...

Typically, chaos-based encryption applications are concerned with encrypting a single type of data, such as an image, text, or sound. Hence, often an encryption approach is restricted to that type of data. This paper explores the aforementioned problem and proposes a novel chaos-based encryption, wh ...

This work studies the problem of chaos-based text encryption. A novel 1-D chaotic map is proposed and studied that exhibits regions of constant chaos, and high values of Lyapunov exponent. Based on the new chaotic map, a pseudorandom bit generator is designed that passes all the National Institute o ...

Augmented and virtual reality, game designing, medicine, medical engineering, and many other fields all revolve around 3D models. This is because 3D models have superior visual information than digital images. However, in recent years the advancements in digital image encryption are more rapid than ...
