Problems solved by technology

There are certain shortcomings in voice communication in the public network, that is, the security and reliability of voice communication are relatively low
This is because the public network uses plaintext to transmit the voice communication between mobile phones. This way of plaintext transmission makes the voice communication between mobile phones easy to be eavesdropped by others, which leads to the leakage of mobile phone user information. Mobile phone users pose a great security risk
Especially for some specific groups, such as governments, agencies, scientific research and other secret-related units, the eavesdropping of voice communication may lead to the leakage of secret-related information, and the consequences are disastrous

Abstract

The present invention provides a method for voice communication encryption and decryption, the method comprising: a first mobile terminal initiates a call to a second mobile terminal through a first STK menu, and the STK menu is provided by a first SIM card in the first mobile terminal ; The first SIM card sends the pre-stored key corresponding to the voice communication between the first mobile terminal and the second mobile terminal to the first communication module in the first mobile terminal, and the key is also pre-stored at the second In the second SIM card in the second mobile terminal; the first communication module encrypts the voice frame sent by the first mobile terminal to the second mobile terminal with a key, and sends the encrypted voice frame to the second mobile terminal; The second communication module in the second mobile terminal obtains the key from the second SIM card after receiving the call from the first mobile terminal; the second communication module uses the key to decrypt the received voice frame. Correspondingly, the present invention also provides a voice communication encryption and decryption system. Implementing the invention can effectively improve the security of voice communication.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for encrypting and decrypting voice communication. Background technique [0002] The emergence of mobile phones has brought great convenience to people's lives, especially the voice communication function, which enables people to communicate anytime and anywhere without being limited by space and region. In the prior art, the voice communication between mobile phones is carried out in the public network provided by the operator. There are certain disadvantages in performing voice communication in a public network, that is, the security and reliability of voice communication are relatively low. This is because the public network uses plaintext to transmit the voice communication between mobile phones. This way of plaintext transmission makes the voice communication between mobile phones easy to be eavesdropped by others, which leads to the leakage...
