Abstract
Multicast communication is becoming the basis for a growing number
of applications. It is therefore critical to provide sound security
mechanisms for multicast communication. Yet, existing security protocols
for multicast offer only partial solutions. We first present a taxonomy
of multicast scenarios on the Internet and point out relevant security
concerns. Next we address two major security problems of multicast
communication: source authentication, and key revocation. Maintaining
authenticity in multicast protocols is a much more complex problem than
for unicast; in particular, known solutions are prohibitively
inefficient in many cases. We present a solution that is reasonable for
a range of scenarios. This approach can be regarded as a `midpoint'
between traditional message authentication codes and digital signatures.
We also present an improved solution to the key revocation problem
