The IP multicast routing infrastructure requires the authentication of control messages and also of data messages. The current work identifies the various categories of authentication keys required within a multicast distribution tree and presents a basic model for their key-management. It also introduces the concept of core authentication routers within the distribution tree that have the additional burdensome task of authenticating data messages. An approach to the management of keys that authenticate control messages is then presented, illustrated using the example of the key arrangement defined for the PIM multicast routing protocol.
