Specific embodiment
The embodiment of the present invention is reference will now be made in detail, the example of the embodiment is shown in the drawings, wherein, identical mark Number identical component is referred to always.It will illustrate the embodiment by referring to accompanying drawing below, to explain the present invention.
Fig. 1 shows the flow of the method for the protection call voice according to an exemplary embodiment of the present invention for electric terminal Figure.Here, the electric terminal includes modem and application processor.
Here, as an example, the electric terminal can be mobile communication terminal (for example, smart mobile phone), can intelligently wear The electric terminal of voice communication can be carried out by wearing equipment (for example, smartwatch), personal computer, tablet computer etc..
With reference to Fig. 1, in step S10, when proceeding by call voice encryption, application processor is received from modem Call voice data packet to be encrypted.
As an example, can when detect proceed by voice communication when, determine to proceed by call voice encryption；And/or It can determine to proceed by call voice encryption when receiving to trigger the encrypted user's operation of call voice.
As an example, application processor, which can be spaced at predetermined time intervals from modem, receives a call to be encrypted VoP.
