     		   "IP Multicast Security"



         Montag, 16.02.2004, 13:00 c.t, IC 4/39

Abstract

T-Systems is currently developing a Multicast Security Gateway, called
MuSeGa, which enables secure content distribution over multicast  networks.
The concept is compatible to the IETF MSEC architecture which  is a general
framework for multicast security at the IP layer. 

IPSec is the well defined and accepted standard for security in unicast  IP.
In the step from unicast to multicast there arise several problems
concerning security: group key agreement, key management, source
authentication, ...

Our main focus in this talk is on the status of standardization  in the
IETF and an overview of efficient group key management algorithms for IP
multicast. 

Presentation language: German (slides in English)
