A secure multilayer audio encryption scheme based on chain ring algebraic S-boxes, Rössler diffusion, and 4D hyperchaotic permutation

Abstract The secure transmission of digital audio requires encryption techniques that can protect audio information against different types of cryptanalytic attacks. Existing chaos-based audio encryption methods commonly use conventional $$\:GF\left({2}^{8}\right)$$ -based substi...

Dynamical Analysis and Backstepping-Based Synchronization of a Fractional-Order Hyperchaotic Yan System Using RBF Neural Networks

This paper explores the dynamic behavior and control of a novel 4D fractional-order hyperchaotic Yan system, characterized by transitions between stability, periodicity, and chaos, driven by fractional-order parameters and initial conditions. The system’s complex nonlinear dynami...
