Further, external voice encryption device based on smart mobile phone also includes the memorizer being connected with described processor.
Further, external voice encryption device based on smart mobile phone also includes the display lamp for showing external voice encryption device and smart mobile phone connection status.
This utility model additionally provides a kind of smart mobile phone, including the mobile phone body possessing data-interface, inserting external voice encryption device based on smart mobile phone on described data-interface, based on smart mobile phone the external voice encryption device that described smart mobile phone is described by data-interface is powered and sets up communication therewith.
Compared with prior art, this utility model has the advantages that
This utility model is communicated with mobile phone by the data-interface (USB interface) of mobile phone, the acquisition process of voice, compression, encryption are all carried out on external voice encryption device, and can guarantee that working key is only stored in external voice encryption device, accordingly even when the implanted virus of smart mobile phone or wooden horse, also it is merely able to the speech data after obtaining encryption, and working key cannot be obtained, thus ensure the safety of voice call.
Accompanying drawing explanation
Fig. 1 is the theory diagram of external voice encryption device.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
Development along with mobile phone technique, smartphone data interface is substantially uniform for data-interface, i.e. usb interface, and generally support usb otg function, main frame can be served as and access external equipment (such as u dish, mouse etc.), and the electric current less than 100ma can be externally provided, make outer being located at when electric current is less than 100ma be no longer necessary to cell powers, the volume of peripheral hardware can be made to accomplish optimum.
As shown in Figure 1, present embodiments provide a kind of external voice encryption device, this encryption device is by realizing communicating between USB interface and the mobile phone of mobile phone, during work, external voice encryption device is inserted on smartphone data interface, being thered is provided power supply by data-interface (usb) for external voice encryption device by smart mobile phone, external voice encryption device completes collection and broadcasting, AD/DA conversion, compressed encoding, the encryption of voice signal, sends to smart mobile phone；Being sent to the communication server by after the smart mobile phone framing again of the encrypted voice data to receiving, the communication server is transmitted to recipient the encrypted voice data received.By above-mentioned design, complete dialog context is encrypted in external voice encryption device, data information transfer between mobile phone, actually transmit is the content after passing through encryption, after calling party or callee obtain encrypted content, then completes deciphering via the external voice encryption device of binding, accordingly even when the implanted virus of smart mobile phone or wooden horse, also it is merely able to the speech data after obtaining encryption, and working key cannot be obtained, thus ensure the safety of voice call.
In the present embodiment, external voice encryption device includes following structure: Mike, receiver, coder, processor, power supply chip, communication interface and memorizer；Wherein, power supply chip is connected with processor and is that the operation of each parts is powered；Two-way communication is carried out, the main conversion being responsible for data between coder and processor；Processor connects the USB interface of smart mobile phone by communication interface, is achieved in the communication with smart mobile phone；During phonetic entry, Mike exports voice signal to coder；During voice output, coder output voice signal is to receiver.External voice encryption device has been used for the collection of upstream voice data, compression, encryption work, is sent to smart mobile phone；Meanwhile, complete the deciphering of downlink data, decompress, play.The cryptographic algorithm that this device can use is as follows: the rivest, shamir, adelmans such as SM2, DES, 3DES；The symmetric encipherment algorithms such as SM4, AES.Above-mentioned AES is existing algorithm, and and therefore not to repeat here.
In order to preferably implement external voice encryption device, the present embodiment is additionally provided with display lamp, and display lamp, after external voice encryption device with mobile phone successful connection, plays indicative function；Or, display lamp, when external voice encryption device is connected unsuccessful with mobile phone, plays indicative function, it is also possible to the two combined, and uses different colours/state to point out.
Calling party is completed by the communication server with the communication of callee, and the foundation of talking link has been responsible for by the communication server, communication link is safeguarded, communicating data forwards, removes the functions such as communication link.
So that those skilled in the art, this utility model application is had apparent understanding and understanding, below to the method using external voice encryption device to realize communication, is specifically introduced.
Communicating pair (calling party and callee) be both needed to configure external voice encryption device；Secondly, the external voice encryption device that communicating pair is configured should be the corresponding external voice encryption device bound in advance, otherwise, it is impossible to normally realize communication.
Work process of the present utility model is as follows: user operation mobile phone enters working interface, and calling party initiates call request, after callee accepts call request, enters talking state.In communication process, performing following steps: one, the external voice encryption device of calling party generates working key W1, PKI P1 and private key S1, the external voice encryption device of callee generates working key W2, PKI P2 and private key S2；Two, the external voice encryption device of calling party transmits after using PKI P2 cryptographic work key W1 to callee, and the external voice encryption device of callee transmits to calling party after using PKI P1 cryptographic work key W2；Three, the external voice encryption device of calling party uses private key S1 deciphering to obtain working key W2, and the external voice encryption device of callee uses private key S2 deciphering to obtain working key W1；Four, the transmission of speech data between calling party and callee: the external voice encryption device of calling party uses W1 encrypted voice data to transmit to callee, and deciphers the speech data received with W2, delivers to receiver after decompression, DA conversion；The external voice encryption device of callee uses W2 encrypted voice data to transmit to calling party, and deciphers the speech data received with W1, delivers to receiver after decompression, DA conversion.
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is; on the premise of above-mentioned design principle; for solving same technical problem; even if some made on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme used is still as this utility model, therefore it should also be as in protection domain of the present utility model.
