Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the invention discloses a kind of speech ciphering method, be applied to voice and send terminal, to improve voice communication safety, described method includes:
Step 101: judge whether user starts to give an oral account character string information in communication process；When judging that obtaining user to start to give an oral account character string information, enter step 102；Otherwise, the character string information that user gives an oral account is directly inputted in mobile radio communication, and again performs step 101 on this basis；
Step 102: start AES, is encrypted to another character string information by the character string information that user gives an oral account；
Step 103: the character string information after encryption is input in mobile radio communication；So far, epicycle voice encryption process completes, and returns step 101 afterwards and starts next round voice encryption process.
Character string implication, described character string information can be bank card number and password, individual's sensitive information such as mailbox user name and password, when not limiting to.From string content, described character string information can be the number sequence comprising several digital numbers and/or several letter numbers.
Whether voice sends terminal can detect whether manual triggering signal starts to give an oral account the criterion of character string information as user in communication process, illustrate: voice sends terminal use before utilizing mobile radio communication that oneself bank card number and password are conveyed to phonetic incepting terminal use, can first pressing voice to send a certain control in terminal and carry out suggestion voice and send terminal oneself and to start typing character string information, voice sends and automatically starts AES after terminal receives prompting the character string information that user gives an oral account is encrypted to another character string information.
Or, by voice recognition mode, voice sends terminal can also judge whether user starts to give an oral account character string information, illustrate: when mentioning the printed words such as " bank card number is ", " password is " in voice call process when voice sends terminal use, voice transmission terminal will automatically start AES and the character string information that user gives an oral account is encrypted to another character string information.
In the prior art, audio encryption is that after noise or noise, (the so-called intelligibility of speech drops in its intelligibility of speech, refer to what one or several speaker was sent out, significant linguistic unit percent can be confirmed as by one or several music-listener through communication system) it is zero, there is obvious encrypted feature, note easily caused by assailant, and the present embodiment keeps the intelligibility of speech constant (what namely listener-in heard is also normal voice) before and after audio encryption, this does not show any encrypted feature after making audio encryption, camouflage property is fabulous, it is difficult to be aware voice signal encrypted, assailant is not easily caused to note.
Phonetic incepting end can decrypt original voice signal automatically, but compared to prior art, voice call content is not done omnidistance encryption by the present embodiment, therefore reduces the decryption burden of phonetic incepting terminal.And, owing to the signal after encryption is still normal voice, facilitate phonetic incepting end subscriber record, therefore phonetic incepting end can not also be deciphered, but by phonetic incepting end subscriber decipherment algorithm according to a preconcerted arrangement, the normal voice under pre-recorded is manually deciphered, this reduces the decryption burden of phonetic incepting end further.
Wherein, the AES that the character string information that user gives an oral account is encrypted to another character string information can be that each character in the character string information to user's oral account rearranges, specific implementation can be, the character string information that user is sent carries out speech recognition, and store each character information respectively, then according to preset order rearranges currently stored each character information, thus the character string information after being encrypted；Or, the character string information that user is sent carries out speech recognition, and in the character voice packet prestored, find out the character information corresponding respectively with each character information, then according to preset order rearranges each character information that current lookup goes out, thus the character string information after being encrypted；Certainly, both specific implementations also it are not limited to.Below, illustrate the cipher round results of this AES: voice is sent to the bank card password that content is " xyz13588660517 " of terminal use's typing, voice sends terminal can be encrypted as " 813x0y571z8665 ", and the voice content sent is reconfiguring of the character that same user truly pronounces, or the reconfiguring of the respective symbols in voice packet.
Or, the AES that the character string information that user gives an oral account is encrypted to another character string information can also be that all or part of character in character string information user given an oral account replaces to other characters, specific implementation can be, the character string information that user is sent carries out speech recognition, the character voice packet prestored finds out the character information corresponding respectively with each character information, then all or part of character information gone out by current lookup replaces to the character information of the other guide in this character voice packet, thus the character string information after being encrypted；Certainly, the character voice packet that this prestores both can be that user prerecords, it is also possible to obtains (downloading as from the Internet) from other approach.Below, illustrate a kind of cipher round results of this AES: voice is sent to the bank card password that content is " xyz13588660517 " of terminal use's typing, voice sends terminal can be encrypted as " 2a5764b32c8943 ", and the voice content sent is the character combination that same user truly pronounces, or non-user prerecords the character combination in voice packet.Or, it is also possible to both AESs are combined as a kind of new AES.
By foregoing description it can be seen that the voice signal that content is character string information is only encrypted by the present embodiment, the signal after encryption is still normal voice, not easily causes assailant to note, thus improve voice communication safety.Additionally, due to voice call content is not done omnidistance encryption by the present embodiment, therefore reduce the decryption burden of phonetic incepting terminal.
