Encrypt Analog voice directly by using raspberry pi3

GSM is the most wide spread mobile communications system in the world. However the security of the GSM voice traffic is not guaranteed especially over the core network. It is highly desirable to have end-to-end secure communications over the GSM voice channel. In order to achieve end-to-end security, speech must be encrypted before it enters the GSM network .

Project requirements:

encryption algorithm :- vse: audio signal variable synthesis encryption algorithm

key exchange :- diffie - hellman (DH) + audio code .

No JB, Do not install APP, No Internet Connection

Analog Voice Encryption
