Embodiment

[0031] In order to solve the problems in the prior art that the voice encryption method for the public communication network is not reliable, technically difficult, and inconvenient to implement, such as figure 1 As shown, the present invention discloses a system for secure communication based on the voice channel of the public communication network, the system includes:

[0032] Power supply: supply power to each module in the system, the power supply can be external power supply or built-in battery;

[0033] Processor: Control the digital-to-analog mapping modulation / demodulation module to perform signal modulation and demodulation, control the voice compression / decompression module to compress and decompress voice, and encrypt, decrypt and process voice signals;

[0034] Digital / analog conversion module: convert the voice signal from analog voice to digital voice, that is, convert the analog voice signal into a digital voice signal on the sending end, and convert the digita...

Abstract

The invention discloses a system and an implement method thereof for secret communications based on a public communication network voice channel. The system and the implement method thereof for the secret communications based on the public communication network voice channel mainly solve the problem in an existing technology that a voice encryption method of a public communication network is low in reliability, difficult in technique and not convenient to implement. The system for the secret communications based on the public communication network voice channel comprises a power source, and further comprises a processor connected with the power source, and a storage, a digital / analog conversion module, a voice compression / decompression module, an encryption / decryption module, and a digital analogy mapping modulation / demodulation module all connected with the processor. By adopting the scheme, the system and the implement method thereof for the secret communications based on the public communication network voice channel achieve a purpose of conveniently and reliably keeping voice communications confidential, and have high practical value and promotional value.

Description

technical field [0001] The invention relates to a security system, in particular to a system for conducting security communication based on the voice channel of the public communication network and its realization method. Background technique [0002] With the continuous development of technology, mobile communication has been widely used as a convenient way of communication. With the increasing popularization of mobile communication technology, the issue of communication security has become increasingly prominent and has become an important topic that people pay attention to. [0003] At present, there are mainly two methods for confidential communication based on the public communication network: [0004] Secure communication method based on data channel: Encrypt by end-to-end voice encryption method, this encryption method is relatively mature in technology, but this method has long call establishment time, large end-to-end delay, poor concealment, High price and other d...
