Group Key Management using IKEv2
draft-yeung-g-ikev2-11
Abstract
This document presents a new group key distribution protocol. The
protocol is in conformance with MSEC key management architecture it
contains two components: member registration and group rekeying, both
downloading group security associations from the Group Controller/Key
Server to a member of the group. The new protocol is similar to
IKEv2 in message and payload formats as well as message semantics.
