The development of innovative methods for concealing critical data in multimedia files has exploded in information security in recent years. Cryptography and steganography cannot be used alone to protect data; rather, they can be combined and used in a single system. Audio steganography is among the most important information security techniques. It involves the concealment of information within audio signals to achieve covert communication. This paper introduces a comprehensive technique that integrates chaos Henon, Baker, and Arnold maps for image encryption with audio steganography to create a robust and secure audio steganography technique. First, the target image is encrypted using chaotic maps. Then, it is embeded within the high frequencies of the cover audio signal based on the Inverse Short Time Fourier Transform (ISTFT) to be transmitted to the destination through the channel. By integrating both encryption and concealment techniques, the cover audio signal quality can be preserved. Moreover, the hidden image security and robustness are improved, making the technique resistant to many types of attacks. The simulation results confirm that the suggested technique is robust in the presence of attacks. It achieves a distinct perceptual quality with an appreciated peak signal-to-noise ratio (PSNR) of 91.2 dB and a Mean Square Error (MSE) of 7.5 × 10. The randomness of the resulting encrypted image has successfully passed the National Institute of Standards and Technology (NIST) statistical test suite.
近年来，用于在多媒体文件中隐藏关键数据的创新方法在信息安全领域蓬勃发展。加密技术和隐写术不能单独用于保护数据；相反，它们可以结合起来并在单个系统中使用。音频隐写术是最重要的信息安全技术之一。它涉及在音频信号中隐藏信息以实现隐蔽通信。本文介绍了一种综合技术，该技术将用于图像加密的混沌亨农映射、贝克映射和阿诺德映射与音频隐写术相结合，以创建一种强大且安全的音频隐写术技术。首先，使用混沌映射对目标图像进行加密。然后，基于逆短时傅里叶变换（ISTFT）将其嵌入到掩护音频信号的高频部分，通过信道传输到目的地。通过整合加密和隐藏技术，可以保留掩护音频信号的质量。此外，隐藏图像的安全性和鲁棒性得到提高，使该技术能够抵御多种类型的攻击。仿真结果证实了所提出的技术在存在攻击的情况下具有鲁棒性。它实现了显著的感知质量，峰值信噪比（PSNR）达到91.2 dB，均方误差（MSE）为7.5×10。所得加密图像的随机性已成功通过美国国家标准与技术研究院（NIST）统计测试套件的测试。
