Encryption earphone and voice communication method thereof

Abstract

The invention discloses an encrypted earphone, which comprises a sound receiving and transmitting module used for receiving and outputting voice; the key generation module is used for generating a key according to a key generation strategy; the voice encryption module is used for encrypting the audio signal; the voice decryption module is used for decrypting the encrypted audio signal; the communication transceiving module is used for transmitting and receiving voice data; the secret key generation module comprises a first secret key factor generation sub-module and is used for generating a binary code according to a password input by a user and taking the binary code as a first secret key factor; the second key factor generation submodule is used for generating a second key factor according to the multiple groups of massive random keys; and the key generation sub-module is used for performing exclusive-or operation on the key factor I and the key factor II to obtain a key. According to the invention, digital coding, encryption and modulation of a sound source are realized through combination of a narrowband voice coding technology and a general password technology, and the method is applied to an encryption earphone.

Description

technical field [0001] The present invention relates to the technical field of earphones, and in particular, to an encrypted earphone and a voice communication method thereof. Background technique [0002] Mobile communication has become an inseparable part of people's work and life, and people's requirements for the confidentiality of voice communication are getting higher and higher. Most of the voice streams of existing communication network communication terminals are not encrypted. The mobile core network does not have the ability to encrypt communication audio data, so voice encryption is a way to achieve secure communication in the process of voice data transmission. [0003] At present, the existing encryption methods used to encrypt the voice data transmission process are mostly realized by encrypting the mobile phone or installing encryption software on the mobile phone, and there are many problems in this method, such as: 1. It is only applicable to a specific 2...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing encryption methods used to encrypt the voice data transmission process are realized by encrypting the mobile phone or installing encryption software on the mobile phone, but there are many problems in this method, such as: 1. It is only applicable to a specific 2. In terms of security, you must rely on and trust a specific service provider, and you cannot achieve security independence; 3. Because it is encrypted by the mobile phone itself, it is very difficult It is easy to be cracked by mobile phone virus software or malicious attack programs, resulting in the leakage of important information
