Below in conjunction with specific embodiment realization of the present invention is described in detail:
Embodiment one
Fig. 1 shows the structure chart of the intelligent terminal that the embodiment of the invention one provides, and described intelligent terminal comprises:
Use processing unit 11, be used for when intelligent terminal is set up the unencryped word conversation voice transfer of the input of control audio frequency, output channel;
In the present embodiment, described application processing unit 11 is communication and control main bodys of software in the intelligent terminal, so when intelligent terminal communicates or various software is installed, may be at application processing unit 11 resident Hacker Program.
Switch unit 12 connects or cuts off with described application processing unit 11 and be connected for the input of switching audio frequency, output channel;
In the present embodiment, switch unit 12 can be electronic device with handoff functionality, electromagnetic device etc., and preferred, described switch unit can be single-pole double-throw switch (SPDT), can realize not only that by single-pole double-throw switch (SPDT) the switching of audio frequency input, output channel selects, and realize simple, cost is low.
In the present embodiment, the speech scrambling of terminal-to-terminal service is the encrypted word conversation, and the non-encrypted conversation of terminal-to-terminal service is unencryped word.
In the present embodiment, during the unencryped word conversation, intelligent terminal is by using the voice transfer of processing unit 11 control audio frequency inputs, output channel, during the encrypted word conversation, cut off to use that processing unit 11 is imported with audio frequency, being connected of the voice transfer of output channel, and by independently encrypting the voice transfer of control unit 13 control audio frequency inputs, output channel, because audio frequency input, output channel break away from the control of using processing unit 11, have reached the purpose that thorough isolation may reside in the Hacker Program of intelligent terminal terminal.
In addition, owing to set up communicating to connect of audio frequency input, output channel and described application processing unit 11 at the described switch unit 12 of control, and cut off in the process that communicates to connect of described audio frequency input, output channel and described application processing unit, adopt the switch unit 12 of physics, can cut off communicating to connect of described audio frequency input, output channel and described application processing unit 11 more completely, further improve the fail safe of intelligent terminal encrypted word phone system.
In the present embodiment, described audio frequency input, output channel comprise: the input of unencryped word audio frequency, output channel and the input of encrypted word audio frequency, output channel.At this moment, described encryption control unit 13 also is used for when intelligent terminal is set up the unencryped word conversation, controls described switch unit 12 and switches to described unencryped word audio frequency input, output channel; And when intelligent terminal is set up the encrypted word conversation, control described switch unit 12 and switch to described encrypted word audio frequency input, output channel.By under different call modes, adopting corresponding audio frequency input, output channel, can guarantee the fail safe of voice call.
Optionally, described encryption control unit 13, also be used for carrying out real-time encrypted to the voice of transmission line, be specially: described encryption control unit 13 carries out real-time encrypted to the voice of transmission line by base station controller, key server and third party's encryption/decryption element, wherein, pass through key server, be used for obtaining the key that the voice that transmit are encrypted, third party's encryption/decryption element is used for according to the key that obtains, and carries out real-time encrypted to the voice of transmission line.
For the ease of understanding, below with a concrete realization example intelligent terminal in the present embodiment is described, but the situation with this realization example is not limited, see also the structure chart that Fig. 2 shows the intelligent terminal system that realization example of the present invention provides, described system comprises intelligent terminal 1, base station controller 2, reaches KMC's server 3, wherein, intelligent terminal comprises application processing unit 11, encrypts control unit 12, single-pole double-throw switch (SPDT) 13 and third party's encryption/decryption element 14.
The course of work of intelligent terminal 1 is as follows: when intelligent terminal is set up the unencryped word conversation, encrypt control unit 12 and switch to path a respectively by two single-pole double-throw switch (SPDT)s 13 of control line L1, L2 control, described audio frequency input, output channel are connected with application processing unit 11, by using the voice transfer of processing unit 11 control audio frequency inputs, output channel; When intelligent terminal is set up the encrypted word conversation, encrypt control unit 12 and switch to path b respectively by two single-pole double-throw switch (SPDT)s 13 of control line L1, L2 control, described audio frequency input, output channel are connected with encryption control unit 12, by encrypting the voice transfer of control unit 12 control audio frequency inputs, output channel.
Wherein, encrypt control unit 12 also with base station controller 2, KMC's server 3 and 14 pairs of transmission courses of third party's encryption/decryption element in the voice to transmission line carry out real-time encryptedly, and it is as follows to finish the process of encrypted word conversation:
When intelligent terminal 1 was caller: the user chose encrypted word conversation instruction and sends to encryption control unit 12, encrypt control unit 12 and base station controller 2,14 pairs of transferring voices of KMC's server 3 and third party's encryption/decryption element are encrypted, detailed process is as follows: encrypt control unit 12 and obtain for encrypted secret key from KMC's server 3, for example, can obtain described key by note, be encrypted according to described key and 14 pairs of transferring voices of third party's encryption software, and the transmission encrypted speech is to base station controller 2, send described encrypted speech extremely to the callee by described base station controller 2, thereby realize the encryption anti-eavesdrop function of voice transfer circuit.
When intelligent terminal 1 when called: encrypt the encrypted word that control unit 12 receives base station controller 2 and call out, with base station controller 2,14 pairs of transferring voices of KMC's server 3 and third party's encryption/decryption element are decrypted, detailed process is as follows: encrypt the transferring voice that control unit 12 receives the secret key encryption of base station controller 12 transmissions, obtain the key that described transferring voice is encrypted from KMC's server 3, be decrypted according to described key and 14 pairs of transferring voices of third party's encryption software, thus the encryption anti-eavesdrop function of realization voice transfer circuit.
In the present embodiment, intelligent terminal switches the audio frequency input by switch unit, output channel connects or cuts off with described application processing unit and is connected, when intelligent terminal is set up the unencryped word conversation, control described switch unit by the encryption control unit and set up the audio frequency input, communicating to connect of output channel and described application processing unit, and when intelligent terminal is set up the encrypted word conversation, control described switch unit by the encryption control unit and cut off described audio frequency input, communicating to connect of output channel and described application processing unit, and control audio frequency input, the voice transfer of output channel, make when unencryped word is conversed, intelligent terminal can normally be realized calling record, online, download and install intelligent terminal general utility functionss such as third party software, and when encrypted word is conversed, can guarantee that intelligent terminal is not subjected to the interference of Hacker Program, prevent that effectively Hacker Program is from the phonetic entry of intelligent terminal, privacy of user is obtained in the output equipment eavesdropping.
