Mohd Mujtaba Akhtar, Muskaan Singh, Virender Kadyan, Mohit Dua

Abstract: Highlights•Proposes chaotic maps and integrates DNA encoding, enhancing the security of audio data.•Utilizes a dynamic sinusoidal map (DSS), sinusoidal fusion with logistic map (SFL), and double DNA operations.•Achieves encryption speed, processing audio signals at 0.0016 kbps, significantly faster than the previous standard of 0.0041 kbps.•Lyapunov exponent also analyzed to demonstrate the chaotic behavior and sensitivity of the encryption process.
