A Testbed for Research and Development of Secure IP Multimedia Communication Services

PI: Ram Dantu, Co-PIs: Elisa Bertino, Sonia Fahmy, Dipak Ghosal, Henning Schulzrinne

  • New services over the Internet, such as Voice over IP (VoIP) and IP-based media distribution (IPTV), are being aggressively deployed. Not only will these services reduce communication costs, but they will also pave the way for innovative, value-added, highly personalized services.

  • Multimedia services are vulnerable to threats such as unpaid service usage and service disruption.

  • New vulnerabilities are possible due to:

  •  Convergence of the public switched telephone network and the Internet

  •  Use of separate signaling and bearer channels

  •  Strict Quality of Service (QoS) requirements

  • Despite the importance of new multimedia services, there is little data on the scalability and vulnerabilities of these services.

  • Example research projects

  • Defense against denial of emergency 911 service

  • Defense against denial of multimedia communication services

  • Spam prevention

  • Impact of security on Quality of Service

Migration Strategy: Replace access first, edge next, and core networks last
