A Toolkit for Secure Internet Multicast
Abstract:
The Internet today supports a basic form of multicast service where anyone can join a multicast group as a receiver. To send data to a multicast group, it's not even necessary to be a member of the group. In other words, Internet multicast in its current form don't support private and authenticated communication. Support for privacy and authentication in multicast can be useful in a number of applications where it is important to restrict the set of receivers and/or authenticate the data source. Applications such as pay-per-view distribution of digital media, pay-per-use multi-party games, and restricted conferences fall in this category.
In this talk, I'll describe our ongoing effort to develop an application toolkit that provides secure multicast services over the Internet. In particular, I'll discuss how our toolkit achieves scalability in terms of group size and group dynamics, and accommodates diverse security and performance needs of various applications. I'll also discuss our initial experiences with the toolkit and the applications that use it.
