An architecture methodology for secure video conferencing

This paper describes how to enhance the security of VoIP applications using hardware security features on computing platforms such as notebooks, tablets and smartphones. Specifically we explain how to develop such applications using the protection offered by a processor based security technology, which provides the ability for software developers to maintain control of the security by creating trusted domains within applications. Using this processor security technology, sensitive code and data can be hosted without the risk of being observed or modified by malware present in other parts of the system. The resulting VoIP applications would better meet the strong security needs of corporate and government sectors for real time digital information sharing. We include results of a research project sponsored by the United States Department of Homeland Security and the United States Air Force Academyⁱ where the team studied ways to enhance the security of a video conferencing application and implemented an experimental Video Chat application using security technologies provided by the processor and media processing hardware.
