Abstract
In data encryption, recently commonly used schemes are chaos-based due to their properties of sensitivity to initial conditions, control parameters, and pseudo-randomness. The chaotic crypto-algorithms are appropriate for extensive data encryption for images, audio or videos. In this paper, a novel audio encryption algorithm based on substitution and permutation network is proposed. In this study, Mobius transformation is used as a source to generate strong S-boxes for the substitution network and the Hénon chaotic map that performs pixel-wise permutation as employed for the permutation network. The proposed algorithm is tested several times with different sizes of audio files; the experimental outcomes show that the proposed algorithm has effective complexity and suitable for audio encryption and hence for secure audio communication.
