Abstract

In multimedia conferencing systems the need for confidentiality and privacy gains more and more in importance, particularly in open networks like the Internet. In this paper we give an overview of the security requirements of multimedia conferencing systems and of applicable security functions. For real-time video transmissions there is a special need for selective encryption of the transmitted data. Existing methods are investigated and their strengths and weaknesses will be shown.

To combine different security functionalities we present the implementation of a scalable security gateway, adaptive to the requirements of specific applications and the properties of special forms of multimedia data.
