Audio Encryption With Computational Chaotic System Error

This paper proposes a novel method of chaos-based encryption for audio. Our method outperformed the minimal requirement of speed for real time audio transfers while maintaining its high security features. The paper exploits finite errors derived from the computation of chaotic systems. The cipher is built on the lower bound error, which is computed by means of two interval extensions of a chaotic system. It was found that the method was effective, and required little computational power in order to be completed, proving to be faster and still reliable compared to other works.
