In this paper, a universal two-dimensional (2D) enhanced cosine coupled model (2D-
ECCM) is first designed, which can construct new 2D chaotic systems using most of the …

In recent years, smart healthcare mode has been gradually maturing with the evolution of
Internet cloud computing technology. However, due to the open and shared features of the …

Some existing image encryption schemes based on chaotic systems have various security
defects, such as non-uniform distribution of the chaotic system's phase trajectory, narrow …

Nowadays, images have an increasingly deep impact on human life, so it is essential to
encrypt images. Among various image encryption methods, chaotic encryption is particularly …

Current multiple-image encryption schemes usually require a fixed number or the same size
of images. Therefore, this paper proposes a multiple-image encryption algorithm that can …

In this paper, we introduce a novel three-dimension chaotic system with strange
characteristic by applying construction of a 3D chaotic circuit method. Multiple equilibria and …

The continuous development of Industry 5.0 technology has brought great convenience to
people's work and life. However, during digital data transmission and storage, the data may …

Chaotic maps, with their unpredictability, sensitivity to initial conditions and control
parameters, are highly suitable for cryptographic applications. However, most chaotic maps …

A new fractional-order 5D hyperchaotic system based on memristor is constructed in this
paper, with the speciality that the system exists chaotic and hyperchaotic states in the …

In recent years, the field of information science has seen a surge in research focused on
digital image security. Chaotic systems have emerged as essential tools in the development …
