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 …

Abstract One-dimensional (1D) chaotic maps have many shortcomings, including simple
structures, uncomplicated chaotic behaviors, and narrow chaotic ranges. Multi-dimensional …

The generation, implementation, and application of multi-scroll chaotic systems have been
extensively studied due to their complex dynamic behaviors. This paper introduces a new …

Chaotic theory is being increasingly researched for application in image encryption scheme
(IES). This paper presents a novel two-dimensional cross hyperchaotic Sine-modulation …

The design of chaotic systems with complex dynamic behaviors has always been a key
aspect of chaos theory in engineering applications. This study introduces a novel fractional …

Digital chaotic maps are severely hampered by the finite calculation accuracy of the
hardware device that is used to implement them, and their applications in cryptography and …

In this paper, we investigate the correlation between the Lyapunov exponent (LE) and the
randomness in chaotic maps. The recently constructed chaotic map has certain limitations …

Designing low-dimensional discrete maps with initial-dependent coexisting property is an
attractive but challenging task. The coexisting property of a discrete map can be featured by …

Secure communication in the digital age is necessary; securing audio data becomes very
critical since this is normally transmitted across susceptible networks. Traditional …
