Problems solved by technology

At the same time, for well-known reasons, voice encryption itself greatly damages the sound quality, and improving the encrypted sound effect is also one of the problems
[0003] Most of the voice call encryption in the existing technology is channel encryption based on a fixed platform, and little attention is paid to the encrypted sound quality

Abstract

The present invention proposes a cross-platform information source voice encryption method and device, including: collecting and processing converted standard PCM data by the sender's mobile terminal, and sequentially performing sound effect processing, routing processing and encryption processing on the standard PCM data, Generate encrypted code stream data, and encode and modulate the encrypted code stream data, and the mobile terminal sends the coded and modulated code stream data to the base station through a wireless channel after carrier frequency modulation; through the base station and the core network, Send the code stream data to the receiver's mobile terminal; the receiver's mobile terminal receives the code stream data, performs decoding, modulation, decryption, audio mixing and routing processing on the code stream data in turn, selects the correct channel to transmit the code stream data, and adjusts the downlink Gain, play the code stream data after gain optimization. The invention can better solve the strong dependence of call encryption on the hardware platform, provides an encryption method with higher security, and adopts a modular idea in scheme design.

Description

technical field [0001] The invention relates to the technical field of mobile communication information security, in particular to a method and device for encrypting voices of cross-platform information sources. Background technique [0002] With the rapid development of mobile terminals, especially smart phones, more and more transactions are processed on mobile phones, and the hidden dangers of mobile phone information security are increasing. The security of voice calls against eavesdropping is one of the hidden dangers. At the same time, for well-known reasons, voice encryption itself greatly damages the sound quality, and improving the encrypted sound effect is also one of the problems. [0003] Most voice call encryption in the prior art is channel encryption based on a fixed platform, and little attention is paid to the encrypted sound quality. Therefore, how to propose a cross-platform voice encryption scheme is a technical problem to be solved at present. Content...
