Secure Group Communication
Speaker: Robert Chirwa, Ph.D. candidate, University of Kentucky; advisor:
Dr. Ken Calvert

Several research groups are investigating solutions to the problem of
securing group communication. The three main research areas are (1) Policy
(2) Group secret key management (3) Data encryption. This talk discusses
some issues in the key management problem area. I will start by giving an
overview of the challenges of secure group communication. Some interesting
schemes proposed to tackle some of these challenges shall be summarized.
Some reliability enhancements to key management suggested by the
University of Texas-Austin team of Yang, Zhang, and Lam at the 2001
Sigcomm conference will be presented. In conclusion, I will talk about how
the solutions proposed by this team solve problems associated with
unreliable key distribution and also speed up key delivery.
