3 Hardware Trojans in Electronic Devices
Features:
• Connection to the user’s phone via Bluetooth interface;
• TopSec Mobile works with nearly all modern mobile phones;
• It can also be used with routers and satellite phones with Bluetooth interface;
• Cannot be identified by a mobile operator;
• Voice encryption is carried out with the help of the Advanced Encryption Standard
(AES) and 256-bit key.
The device employs complex combination of asymmetrical 1024-bit encryption
and symmetric 128-bit encryption to ensure a high protection level. Figure 3.14
demonstrates the operating principle of this device in a distributed communication
system.
In order to establish a secure connection, the user only needs to dial a number and
press the button “crypto”. The other subscriber also needs to use TopSec GSM or a
stationary phone equipped with similar equipment, such as ELCRODAT 6-2 ISDN
by Rohde & Schwarz. This company started selling such devices after purchasing the
hardware encryption department from the company Siemens Information & Communication Mobile. TopSec GSM works in two frequency ranges, 900 and 1800 MHz,
due to which it can be used in any region where GSM 900/1800 networks are available. The company sells new models in many countries of the world at about 3
thousand dollars.
The downside of this approach is having a dedicated server for control over calls
between subscribers registered on the server. However, this is a necessary condition
for designing a distributed interaction system.
