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...
