  1. Defense Communication Strategy&Communication 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)

  4. 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
