Abstract:
1. A method for managing session keys for a secure multicast group that includes a plurality of multicast proxy service nodes in a communication network, the method comprising the steps of: creating and storing an original session key associated with the secure multicast group in a first directory; receiving through periodic replication of the first directory a new session key for the secure multicast group, for use after addition of a first multicast proxy service node to the secure multicast group, from a second multicast proxy service node of the plurality of multicast proxy service nodes; and receiving the new session key comprises receiving the new session key from a replication service agent (RSA) that is operable to replicate key information from a local copy of the first directory that is associated with the second multicast proxy service node; wherein the local copy of the first directory is associated with a directory system agent (DSA) for communicating with one or more of the multicast proxy service nodes that include the second multicast proxy service node.
