Cipher Unit for Mobile GSM - UMTS - THURAYA
The 3177-V cipher unit has been designed to meet the stringent requirements for speech security which is s necessary in modern communications.
The device is built to be used with many mobile phones via a cable or wireless via the Bluetooth interface.
The flexible interface makes it possible to have a simple plug con-nection to most of the modern equipment of various manufacturers.
Beside the widespread GSM standard the 3177-V allows also to work with Thuraya satellite equipment. The cipher unit delivers a good audio quality including speaker rec-ognition in real-time.
Thus, for the first time it is possible to transmit confidential information with high security end-to-end via the normal voice channel of either mobile phones (GSM) or satellite net-works (Thuraya).
The 3177-V cipher unit is a quite new concept in high grade voice encryption by a multi mode system using time and frequency domain via a vocoder. Due to the most modern technology the 3177-V cipher unit requires only a low band width which is satisfied by the normal voice channel a mobile phone offers.
Because there is no need of any additional technical feature beside the voice channel, no GSM provider has to be asked the make the data channel available which never de¬livers a reasonable voice quality due to its package switching feature.
New keys can be loaded by using a PC-based application or a key gun linked to the 3177-V cipher unit via its interface.
The entire high sophisticated electronic is packed in a small separate housing. Thus, it does not depend on a certain model of mobile phone but can be even reused when the mobile itself is replaced. Because the interfacing is done via the connection cable all you need in that case might be a new cable for the connection between the new mobile and the 3177-V cipher unit.
Because the cipher unit has its own power supply it does not need to be charged by the battery of the mobile phone and thus does not touch its operation time.
