ABSTRACT:
An embodiment of the present invention provides a method for heterogeneous secure associations in Wireless Fidelity Personal Area Networks (WiFi PAN), comprising designating as a regular mobile node (MN) a MN which establishes a security association with a PAN Master as it advertised by the PAN Master and designating as an outstanding MN as a MN which establishes a security association which differs from that advertised by the PAN Master; and differentiating by the PAN Master between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both the Regular MN and the Outstanding MN are subscribed to the multicast address, then the PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model and to regular MN as regular multicast frame.
