Problems solved by technology

The voice channel has the advantages of less full-duplex delay, but in mobile communication standards such as GSM, the original voice signal itself is not encrypted, but is encrypted at the communication protocol level. If the channel is cracked and monitored, there is a risk of leakage
The data channel can encrypt the voice signal and then transmit it, but because of the different requirements of communication specifications, the real-time performance of the data channel is not as good as that of the voice channel, there will be a certain delay in the call, and the

Abstract

The invention discloses a mobile terminal capable of encrypting voice information and an encryption method thereof. The mobile terminal comprises an encryption and decryption module, a first mobile phone communication module and a second mobile phone communication module. In the invention, voice information acquired by a microphone is encrypted through the encryption and decryption module; the encrypted voice information is transmitted to the first mobile phone communication module; the first mobile phone communication module transmits the voice information to another mobile terminal communicating with the mobile terminal; and the encryption and decryption module also transmits a secret key to another mobile terminal through the second mobile phone communication module. According to the invention, separate transmission of secrete keys of the voice information is realized; the encryption security is improved; after the secret key and the voice information output by another mobile terminal are received, the voice information is encrypted through the encryption and decryption module; therefore, decryption of the voice information is realized; even though any channel of two communicating mobile terminals is monitored, a monitor cannot obtain all information; and thus, the encryption security is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile terminal capable of encrypting voice information and an encryption method thereof. Background technique [0002] According to the existing mobile communication standards for mobile phones, voice calls use the voice channel, while data services use the data channel. The voice channel has the advantage of less delay in full-duplex, but in mobile communication standards such as GSM, the original voice signal itself is not encrypted, but is encrypted at the communication protocol level. If the channel is cracked and monitored, there is a risk of leakage. The data channel can encrypt the voice signal and then transmit it, but because of the different requirements of communication specifications, the real-time performance of the data channel is not as good as that of the voice channel, there will be a certain delay in the call, and the user experience is not good;...
