Secure GSM

Inbuilt Secure GSM Application,

Stratign’s advanced Inbuilt Secure GSM Application (STN-ISG3G) is a versatile encryption software application designed to protect phone calls from eavesdropping. STN-ISG3G offers unparalleled level of security due to point-to-point encryption with fully secure duplex communication. The inbuilt secure GSM software also ensures high quality audio and a noise-free background.

It works as peer-to-peer to provide end-to-end security if the data network provides a global IP address; or else it can work through the ISG3G server which can be customer owned & managed and even located at the customer’s premises. Otherwise, the server can be provided at a secure location where it can be managed under Stratign’s arrangements.

With STN-ISG3G, you can enjoy encrypted text messages, voice calls, file transfers, video messages and group chats – making communication safe like never before. This GSM phone application does not involve secure calls going through third party servers which further prevent unexpected data theft from happening in the first place. All one-to-one communication audio calls are performed in point-to-point mode.

A new end-to-end key exchange is performed prior to every call. Encryption of every audio packet is done by using AES 256 in GCM mode. A Signaling server is deployed for purpose of call signaling – informing other party about an incoming call. End-to-end encryption of audio packets prevents the Signaling server to decrypt audio data even if the server gets to intercept the P2P UDP traffic between two clients.
