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 part
The receiver part decrypts the voice and hears it normally
End to end encrypt
Hi, analog speech encryption or scrambling is comparatively complex process thn digital encryption.
My plan is to read the analog audio signal from microphone (or any other source) in raspberry pi ie converting it to digital domain, doing encryption or decryption and converting back to analog domain and send it back to the microphone pin o the audio connector to fed that to mobile or speaker(decryption end),
The system will not be connected to internet or any external source, it will not use any external or internal database and server. there will be only audio in/out in this system.
Do you have any requirement about the encryption algorithm. In your budget I can provide basic encryption only
Please inbox me for more details.
Hi,
so we can use a software that won't be easy to tweak but in the end we can encrypt GSM using the same very strong algorithms used on internet connections
