| Summary: | This paper proposes a cost-effective key management
method for multicast networks. This method divides a
multicast group into several subgroups, where the multicast
transmission is separated into two levels, namely, multicast and
unicast level. We model our proposed method based on the
cost of join and leave operations in the multicast group using
Markov chain and Poisson Arrival Process. Then, we compare
its performance (by means of analytical) against typical key treebased
methods. The results show that our proposed method
significantly reduces key update cost compared to the existing
ones. |
