“…Performing secure end-to-end voice communication is difficult due to limitations such as limited bandwidth, lossy compression, and noisy channels. Standard digital encryption is not suitable for limited channel bandwidth [11] as encryption adds overheads [3]. The human voice range extends from 100 Hz to 17 kHz, but traditional narrowband telephone calls limit audio frequencies from 300 Hz to 3.4 kHz.…”

Secure end-to-end voice communication is crucial, but it has several issues. Researchers in this field can benefit from a review paper with broader evaluation parameters than existing literature and from a coverage of security algorithms for voice communication. This paper provides a comprehensive overview of end-to-end secure voice communication and evaluation of various methods for securing voice transmissions over communication networks. The evaluation parameters include System Throughput Capacity, Transmission Error Rate, Recovered Speech Quality, and Security of the System. The analysis results show that Steganography category is the most popular technique in recent years and the most promising category to implement high system throughput capacity. Modem-based Cryptography category is the most promising category to implement standard security algorithms with low system throughput capacity. Meanwhile, chaotic Cryptography provide suitable cryptography for voice security. Furthermore, the results reveal gaps in proposed solutions, including the evaluation and improvement of speech quality, the need for further development of compatible method to implement standard security algorithms, and the extensive development space for Artificial Intelligent based method.

This article considered the guarantee of confidentiality task of audio information transmitted over a packet communication channel. Domain analysis showed, that in most cases cryptographical method used for guarantee of confidentiality of audio information, however, along with them, matrix methods of protective coding used, with implementation on FPGA or DSP processors. These methods, using random matrices, impose additional instrumental errors during decoding. The purpose of the study: is to assess the quality of protective coding ‒ masking of audio data by quasi-orthogonal structured matrices. The proposed method of masking digital audio information by quasi-orthogonal matrices differs from the known ones in predictable results and simplity of implementation. An alternative approach to the classical use of metrics is proposed for evaluating the result of masking. It is based on the analysis of the spectral component of the signal. It is shown that masking with a square Mersenne ‒ Walsh matrix brings digital audio information, presented in the form of a matrix, to a form close in spectrum to white noise. This reliably protects it in the communication channel from unauthorized access. The obtained results showed that the proposed method is promising and suggests the study of the influence of the choice of orthogonal matrix structures and their sizes on the results of masking.
