ABSTRACT:
This invention provides a bandwidth-efficient mechanism whereby the source or originating node(s) (the invention supports multiple source nodes, each creating single or multiple broadcast message(s)) may utilize broadcast addressing service to efficiently reach multiple receiver nodes and still control which receiver node(s) may access the broadcast data or message. This method is realized by a novel and efficient key distribution technique.
