Summary:A system for multicasting a data packet in a multicast group includes a network entity, and a plurality of members of the multicast group. A member can notify the network entity of a rogue member of the group claiming an identity of a spoofed member of the group. In response to being notified, the network entity can distribute, to at least the members of the group other than the spoofed member, different versions of a symmetric key associated with the spoofed member. The member notifying the network entity of the rogue member can then receive a next data packet and a code for the next data packet, the code having been generated at the rogue member using a version of the symmetric key associated with the spoofed member such that the rogue member can be identified based upon the version of the symmetric key.
