Encryption/Decryption Analog voice directly OVER GSM BY USE - raspberry PI 3|B OVER GSM

******** Please read the description carefully *******

****Many programmers and engineers failed to complete the project****

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

Analog Voice Encryption

Encrypting voice of mobile calls (GSM, CDMA, LTE, APP ... calls) directly. Encrypt voice contents before sending into cell phone. Prevent intercept at phone, base station and Telecom server site. Analog encryption guard against crack and hack. Secure your voice contents extremely.

No APP Installation

No Server involvement

project doesn’t need internet connection. project communicate through voice channel. Won’t save or transfer log/key by 3rd party. Less exposure and higher security.

Provide unlimited encrypted phone call minutes. No licenese limitation. Secure phone call forever.

The phone is used to send encrypted voice between the parties.

The piece contains two parts

Part of the sender

Part of the receiver

Where the sender - sends the encrypted voice by phone to the other party

The receiver part decrypts the voice and hears it normally

Encryption and decryption are in real time

One piece works as a sender and recipient at the same time
