This paper describes support for batch rekeying in Mykil, a
key management system for supporting secure group mul
ticast. Batch rekeying in Mykil allows for substantial re
ductions in the cost and complexity of rekeying operations,
arguably the expensive portion of the system. By accumu
lating join and leave operations and utilizing an algorith
mic approach to minimize the number of necessary rekey
ing messages, Mykil can achieve a marked reduction in the
total number and size of messages and can signiﬁcantly
streamline the system’s operation.
