摘要

在日益数字化的世界中,由于保护知识产权和保护敏感的个人信息的需求日益增长,最近对音频数字加密的研究得到了加强。随着音乐、播客和私人通信等音频内容越来越容易获得,并通过在线平台广泛传播,未经授权访问和盗版的风险也在上升。加密在确保创作者和制作人保持对其作品的控制,从而防止未经授权的复制和分发方面起着至关重要的作用。对加密的关注不仅是为了保护经济利益,也是为了在数字盗窃和非法共享普遍存在的情况下维护知识产权的完整性。高级加密标准AES (Advanced Encryption Standard)是美国政府国家标准与技术研究院采用的一种正式加密方法,在世界范围内被广泛接受。在本文中,我们提出了一种基于AES和丛技术混合的音频加密方法。通过AWGN和瑞利信道的传输测试了所提出的方法。AES是一种分组密码算法,它在一个加密密钥中使用几轮加密。在我们的研究中,AES加密算法采用128位块大小,相当于16字节的长度。“轮”定义了AES算法根据密钥长度重新加密数据的混合过程。Plexus算法依靠排列原理将数据随机化以降低误码率。混合使用两种算法可以提高传输质量和加密强度。

Audio plexus encryption algorithm based on AES for wireless communications
Recent research in digital encryption for audio has intensified due to the growing need to safeguard intellectual property and protect sensitive personal information in an increasingly digital world. As audio content, such as music, podcasts, and private communications, becomes more accessible and widely distributed through online platforms, the risk of unauthorized access and piracy also rises. Encryption plays a crucial role in ensuring that creators and producers maintain control over their work, thereby preventing unauthorized copying and distribution. This focus on encryption is not only about protecting financial interests but also about preserving the integrity of intellectual property in a landscape where digital theft and illegal sharing are prevalent.
The Advanced Encryption Standard (AES) is a formal encryption method adopted by the National Institute of Standards and Technology of the US Government, which is accepted worldwide. In this paper, we propose a hybrid approach which is based on mixing of both the AES and plexus techniques for audio encryption purpose. The proposed approach is tested through the transmission over AWGN and Rayleigh channels. The AES is a block cipher algorithm, which uses several rounds within an encryption key. In our study, the AES encryption algorithm is applied with 128 bits block size, which equal to 16 bytes in length. The “rounds” define the mixing process in which the AES algorithm re-encrypts the data depending on the key length. Plexus algorithm depends on permutation principle that randomizes the data as a way of reducing the bit error rate. Mixing the two algorithms will develop both the transmission quality and the encryption strength.

期刊介绍: Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
