Главная Криптофон



Стандарт GSM не обеспечивает должного уровня безопасности телефонных разговоров. Разговор может быть прослушан через оператора связи, через различные активные, полуактивные и пассивные комплексы перехвата GSM.

Мы предлагаем вам программy для защиты разговора по сотовому телефону от прослушивания:

Secure Voice GSM — для защиты разговоров на базе Symbian

Secure Voice GSM

Technical Data

Voice encryption algorithm: AES 256/AES256 or ARC4;
Key exchange algorithm: Diffie-Hellman 4096;
Call authentication algorithm: RSA 1024 key;
Voice compression: AMR-NB 4.75 Kbps;
Voice encryption encoding: End-to-end, Full-duplex;
Roaming support: Yes;
Man in the middle protection: Yes.

Please make sure that the Data Call (CSD) facility is enabled on your SIM card, otherwise the Secure Voice GSM software will not work.

User Interface

Secure Voice GSM has intuitive interface, works reliably in the background and uses very little system resources. Some software screenshots can be seen below.




1. Main application screen: you can either enter a phone number manually or select one from the phone's contact list




2. By pressing the dial button the Secure Voice GSM software starts to establish a secure connection with another cell phone (installed Secure Voice GSM is required).




3. Once connected, the authentication process starts.




4. Once authentication is successful, the key exchanging process begins.




5. Encrypted connection is established successfully. You may now start your conversation in secure mode!




We have worked hard to make wide list of devices available for you to use with Secure Voice.
However please be sure that the devices are compatible with Secure Voice on Your GSM Network.

Please also try to use first of all devices that are 100% compatible and that we have tested personally before trying the possible compatible ones.
