Dynamics and Entropy Analysis for a Novel Sine-Cosine 5-D Hyper-Chaotic System and its Utilization for lightweight RGB Image Encryption

Résumé

In this paper, we presented a new sine-cosine 5-D hyper-chaotic system that
has 2+ve and large maximum Lyapunov exponent compression with all system 5-D different
previous studies with superior Kaplan-Yorke Dimension. This nonautonomous
system consists of sixteen terms, nine of them non-linear, and every equation includes
either a sine or cosine function with one zero unstable equilibrium point. We proved
that the highly complex bounded attractor hyperchaotic system by information analysis,
different analyses, including symmetric, SDIC, Kaplan-Yorke dimension, zero-one test,
multistability, Lyapunov exponent, dissipative, equilibrium pt., stability proposed systems,
bifurcation analysis, and Routh stability. Furthermore, we apply a 5-D sine-cosine hyperchaotic
to generate a matrix (SSMK Generation) that has special properties. Moreover,
we used the proposed system for RGB image encryption, which involves a two-part process.
The initial part entails scrambling of colored images, while the second part employs
a system in permutation, to give a better level of security while being easy to use to create
a new algorithm based on the proposed system. It has proven the efficiency and speed
of image encryption. We used MATLAB 2021b and Mathematica 13.2 to simulate and
offer results.
