Technical field
The utility model relates to communication security technical field, is specifically related to one voice encryption system end to end.
Background technology
Mobile communication has become the indivisible part obtained of people's Working Life, and the confidentiality requirement of the voice communication between people opposite end and end is also more and more higher.Voice flow between existing communicating terminal is not mostly through encryption.Mobile core network does not possess the ability to the encryption of communication voice data, is therefore a kind of mode realizing secure communication at voice data transmission process voice encryption.
Utility model content
Technical problem to be solved in the utility model is to provide one voice encryption system end to end, can ensure end-to-end between the fail safe of voice call.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
The utility model provides one voice encryption system end to end, described system comprises transmit leg communicating terminal and recipient's communicating terminal, described transmit leg communicating terminal comprises the microphone connected successively, first signal conditioning circuit, encoder, phonetic cryptographic coder and first communication module, described recipient's communicating terminal comprises the second communication module connected successively, voice decipher, decoder, secondary signal modulate circuit and loud speaker, described phonetic cryptographic coder is connected with voice decipher by the first communication module in transmission communicating terminal and the second communication module in recipient's communicating terminal.
The beneficial effects of the utility model are: in transmit leg communicating terminal, arrange encoder and phonetic cryptographic coder, decoder and voice decipher are set in recipient's communicating terminal, ensure the fail safe of voice call between transmit leg communicating terminal and recipient's communicating terminal.
On the basis of technique scheme, can also be improved further.
Further, described first signal conditioning circuit comprises squelch circuit and shaping filter amplifying circuit, and described secondary signal modulate circuit comprises signal amplification circuit.
Described further beneficial effect is: carry out denoising sound and shaping filter amplification to the voice signal of the transmit leg gathered, make voice signal purer.
Further, in described phonetic cryptographic coder, be provided with fingerprint extraction module, to extract the fingerprint of transmit leg user.
Further, in described voice decipher, be provided with fingerprint identification module, identify with the fingerprint of the transmit leg user extracted described fingerprint extraction module.
Described further beneficial effect is: in the phonetic cryptographic coder of transmit leg communicating terminal, arrange fingerprint extraction module, extract the fingerprint of transmit leg user, corresponding, in the voice decipher of recipient's communicating terminal, fingerprint identification module is set, be used for identifying the fingerprint of transmit leg user, when identify fingerprint identical with the fingerprint of transmit leg user time, deciphering ability by, ensure that the fail safe of voice call.
Further, described first communication module and second communication module are communication.
Further, described communication is radio communication mode or Blue-tooth communication method or WIFI communication mode.
Accompanying drawing explanation
Fig. 1 is the one voice encryption system schematic end to end of the utility model embodiment.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment, one be voice encryption system end to end.Below in conjunction with Fig. 1, the encryption system that the present embodiment provides is described in detail.
See Fig. 1, the voice encryption system that the present embodiment provides comprises transmit leg communicating terminal and recipient's communicating terminal, described transmit leg communicating terminal comprises the microphone connected successively, first signal conditioning circuit, encoder, phonetic cryptographic coder and first communication module, described recipient's communicating terminal comprises the second communication module connected successively, voice decipher, decoder, secondary signal modulate circuit and loud speaker, described phonetic cryptographic coder is connected with voice decipher by the first communication module in transmission communicating terminal and the second communication module in recipient's communicating terminal.
Wherein, described first signal conditioning circuit comprises squelch circuit and shaping filter amplifying circuit, and described secondary signal modulate circuit comprises signal amplification circuit.Fingerprint extraction module is provided with in described phonetic cryptographic coder, to extract the fingerprint of transmit leg user, corresponding, be provided with fingerprint identification module in described voice decipher, identify with the fingerprint of the transmit leg user extracted described fingerprint extraction module.
Second communication module in first communication module in transmit leg communicating terminal and recipient's communicating terminal adopts communication, and communication is specifically as follows radio communication mode or Blue-tooth communication method or WIFI communication mode.
The course of work of the system of voice encryption end to end adopting the present embodiment to provide is: the microphone of transmit leg communicating terminal gathers transmit leg call voice, noise treatment and shaping filter is gone to amplify process through the call voice of the first signal conditioning circuit to analog form, and through encoder, analog signal is encoded to digital signal, and the voice signal of digital form is inputed in phonetic cryptographic coder, fingerprint extraction module in phonetic cryptographic coder extracts the fingerprint of transmit leg user, and carry in voice signal after encryption, and the voice after the encryption carrying transmit leg user fingerprints are sent to the phonetic cryptographic coder in receiving terminal communicating terminal by first communication module and second communication module, wherein, fingerprint identification module is provided with in voice decipher, only have after the fingerprint recognition of transmit leg user is passed through, voice decrypting process just by, the voice of the digital form after deciphering through decoders decode be analog form, and through secondary signal modulate circuit, amplification process is carried out to the voice of analog form, the loud speaker exporting recipient's communicating terminal to is play.
The one that the utility model provides is voice encryption system end to end, encoder and phonetic cryptographic coder are set in transmit leg communicating terminal, decoder and voice decipher are set in recipient's communicating terminal, ensure the fail safe of voice call between transmit leg communicating terminal and recipient's communicating terminal; In addition, in the phonetic cryptographic coder of transmit leg communicating terminal, fingerprint extraction module is set, extract the fingerprint of transmit leg user, and corresponding fingerprint identification module is set in the voice decipher of recipient's communicating terminal, only have when the fingerprint identified is the fingerprint of transmit leg user really, the deciphering of voice just by, for the voice call between end-to-end further increases one deck guarantee.
In the description of this specification, concrete grammar, device or feature that the description of reference term " embodiment one ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, method, device or feature can combine in one or more embodiment in office or example in an appropriate manner.In addition, when not conflicting, the feature of the different embodiment described in this specification or example and different embodiment or example can carry out combining and combining by those skilled in the art.
