Fips 140 Level 2 Transec Security Module - Comtech EF Data DMD1050TS Installation And Operation Manual

The Baseband Printed Circuit Card also contains the M&C Circuitry responsible for:
•
Programmable part setup and initialization
•
Continuous control and adjustment of some functions
•
Calibration
•
Monitoring fault status
•
Calculating and displaying measurements
•
Calculations
•
User monitor and control interface including any remote interface
•
Unit configuration and feature set
The M&C System is based on a powerful microprocessor with a large amount of Flash memory.
Several bus architectures are used to interconnect the M&C to all components of the
DMD1050TS. Communication to the outside world is done via connections to the remote port,
terminal port, Ethernet port and alarm port. The M&C runs on software programmed into its Flash
memory. The memory can be reprogrammed via the Ethernet port to allow changes in software.

3.1.3 FIPs 140 Level 2 TRANSEC Security Module

The DMD1050TS Modem Card is optionally equipped with the FIPs 140 Level 2 Transmission
Security (TRANSEC) Security Module in standalone operation with the DMD1050TS Modem.
The Federal Information Processing Standards (FIPS) Module is a standalone, independently-
certified optional card that is secured to the DMD1050TS baseband processing card. It does bulk
encryption and decryption of traffic over the satellite, using the AES-256 algorithm.
The DMD1050TS is fully compatible and interoperable in all specified modes of operation with
KIV-19 Provisional and KG-95-1 Provisional TRANSEC equipment used by the Government.
