Reliable and Secure Group Communication

Reliable and Secure Group Communication

• Personnel Deb Agarwal, Karlo Berket, Guillaume
  Egles, and Olivier Chevassut

Objectives Developing the InterGroup protocol
which is a reliable multicast protocol intended
to scale to large group sizes and to the
Internet. Developing a Secure Group Layer that
provides a secure channel abstraction similar to
Secure Sockets Layer (SSL), but for multicast
2
