Information Security

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).

Ý-484 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 channels.

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 ( Qualcomm GSP1620 satellite modem, Qualcomm GCK1410 car kit on the basis of Qualcomm GSP1600 UT) with M-484.

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.
