TRANSCRIPT

A Testbed for Research and Development of Secure IP Multimedia

Communication Services

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.

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

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
