Abstract
En 中文
Audio encryption is critical for securing digital communications and protecting sensitive audio data from unauthorized access. In this study, we address the challenge of enhancing security and efficiency in audio encryption by proposing a novel encryption strategy that combines Dynamic Sinusoidal System (DSS) and Sinusoidal Fusion with Logistic (SFL) chaotic maps, along with double DNA operations. The primary objective is to develop a robust encryption system capable of resisting modern cryptographic attacks while improving performance. The experimental results clearly demonstrate the effectiveness of our approach. The bifurcation analysis of the proposed chaotic maps shows a broader chaotic range with no stable windows, highlighting the system's ability to generate highly unpredictable behavior essential for encryption. Additionally, the chaotic maps exhibit positive Lyapunov exponents, confirming the system's sensitive and chaotic nature. Our method also achieves a substantial improvement in time efficiency, with an encryption rate of 0.0016 kbps, compared to the state-of-the-art rate of 0.0041 kbps, resulting in a significant improvement of 0.0025 kbps. These findings validate the proposed system's ability to provide highly secure and efficient encryption for audio data.
