Encryption/Decryption Analog voice directly by using raspberry pi0

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:

No JB, Do not install APP, No Internet Connection
