Defense Communication StrategyCommunication
Infrastructure

• Hilmi Sanusi
• Institut Sains Angkasa
• Universiti Kebangsaan Malaysia

2
Defense Communication through Satellites WHY?

• Better mobility
• Satellite as relay
• Higher bandwidth
• Multimedia content
• More information can be transferred
• Better tactical ability
• Longer distance

3
Defense Communication through Satellites CONS

• Counter measure
• Jammed using Frequency Interference
• Eavesdropping
• Signal interception
• Weather..
• Rain attenuation (Ku band)

Satellite Communication Definition
5
The Needs of Secured Communication

• Satellite Communications Must Be Secure
• Satellite uplink commands must be encrypted and
  authenticated to assure legitimate control of the
  satellite and its operation.
• Sensitive and classified communications via
  satellite must be encrypted to protect them from
  interception and compromise.

6
The Needs of Secured Communication in Military

• Satellite Communications Encryption
• satellites must employ authenticated and
  encrypted command links, and encrypted downlinks
• Develop Standard to authenticate satellite
  command links and services
• Hierarchy of controlling the authenticated
  command links

7
Satellite Communications Encryption

• Provides the end-to-end security and integrity of
  such message exchange
• A data protection mechanism
• Develop own encryption method
• Where How to implement
• Network or Data-link layer
• Hardware / reconfigurable encryption
• Modulation scheme (CDMA for counter measure)
• Different encryption for different purposes
• Biometric??? (to differentiate access)

8
Goals for Secured Satellite Communication

• Best possible use of limited bandwidth
• High link utilization
• Conservation of power
• Prioritization of traffic
• Tolerant of intermittent connectivity
• High forward/return link asymmetry

9
Data integrity and Data Security Standard

• Should create appropriate standard to ensure the
  security of the data
• The encrypt and decrypt data should maintain the
  same fidelity
• At least follow the standard of the Consultative
  Committee for Space Data Systems (CCSDS ) or
  International Organization for Standardization
  (ISO) for Aircraft and Space Vehicles

10
VSAT . . .

• Provides secure solutions through VSAT
• Interception, Monitoring and logging systems.
• Authentication
• Wireless Local Loop WLL
• Coverage
• Better control of the network
