2 3rd AFCEA Europe Student Conference, London 2010 2 Outline Introduction Main elements of NNCS Hidden Protocol Bridges Master Resident Implementation References

3 3rd AFCEA Europe Student Conference, London 2010 3 Introduction What is NNCS? National Network Centric System is a military platform for information warfare that takes advantage of the hidden data transmission to gain informational lead over a potential enemy.

4 3rd AFCEA Europe Student Conference, London 2010 4 Main elements of NNCS Hidden Protocol Interpreters Master Resident Hidden Protocol Bridges Hidden data links (Voice over IP, PSTN, GSM, VHF, Wi-Fi and Video over IP soon)

5 3rd AFCEA Europe Student Conference, London 2010 5 Hidden Protocol Bridge HPB is the connection between two types of data links. There are two types of HPB: - HPB-H (hardware bridge) - HPB-S (software bridge)

6 3rd AFCEA Europe Student Conference, London 2010 6 HPB-H Data link #1 (eg. VoIP) Data link #2 (eg. PSTN) Audio signal with embedded watermark

7 3rd AFCEA Europe Student Conference, London 2010 7 HPB-S Watermark embedder Audio signal sourceHidden information RS/BCH coder eg. VoIP call Watermark extractor RS/BCH decoder RS/BCH coder Watermark embedder Audio signal source eg. GSM call HPB-S
