The St.-Petersburg Regional Center of the Information Security (SPb RCZI), which specializes in
development of information protection cryptographic systems, in February 2003 carried out
complex tests of M-484
devices to check their application for cryptographic protection
of the information transmitted through satellite communications channels by means of
źGlobalTel╗ equipment (the FAPSI Certificate registration No. SF\020-0321 dated 06.03.2000).
Cryptographic Information Security System device M-484
The M-484 is designed to operate independently irrespective of the data transmission mode
selected by the customer; it was required to confirm this feature for the GlobalTel satellite
The M-484 is connected to the RS-232c standard asynchronous interface between the computer
(or another information processing unit) and the HAYES-modem, providing the cryptographic
information protection rate of up to 115 kbps.
The given devices allow to transmit through satellite channels the information with the
security classification of źconfidential╗, źstrictly confidential╗ and źclassified╗.
Tests diagrams are shown on the following Figures:

The NetMeeting programme was used as the tests software.
The tests confirmed full compatibility of the GlobalTel equipment (
modem, Qualcomm GCK1410 car kit
on the basis of Qualcomm GSP1600 UT)
The rate and quality of data transmission in communications channels are determined by the
satellite channel data rate and does not change when M-484 is connected. The point-to point
data rate during testing was from 2.0 to 8.4 kbps.
