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 .
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
This video is only to explain and understand the idea well
