Methods, apparatus and systems configured for heterogeneous secure associations in Wi-Fi PAN
First Claim
1. 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 said PAN Master and designating as an outstanding MN as a MN which establishes a security association which differs from that advertised by said PAN Master; and
differentiating by said PAN Master between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both said Regular MN and said Outstanding MN are subscribed to said multicast address, then said PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model, wherein said MN and said Master are implemented in hardware or a combination of hardware and software.

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.

7. An apparatus, comprising:
-
a mobile node (MN) operable in a Wireless Fidelity Personal Area Networks (WiFi PAN) using heterogeneous secure associations; wherein said MN is designated as a regular MN which establishes a security association with a PAN Master as it advertised by said PAN Master or designated as an outstanding MN which establishes a security association which differs from that advertised by said PAN Master; and wherein said PAN Master differentiates between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both a Regular MN and an Outstanding MN are subscribed to said multicast address, then said PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model, wherein said MN and said Master are implemented in hardware or a combination of hardware and software. - View Dependent Claims (8, 9, 10, 11)

12. A non-transitory machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:
enabling heterogeneous secure associations in Wireless Fidelity Personal Area Networks (WiFi PAN) by designating as a regular mobile node (MN) a MN which establishes a security association with a PAN Master as it is advertised by said PAN Master and designating as an outstanding MN an MN which establishes a security association which differs from that advertised by said PAN Master, and differentiating by said PAN Master between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both said Regular MN and said Outstanding MN are subscribed to said multicast address, then said PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model, wherein said MN and said Master are implemented in hardware or a combination of hardware and software. - View Dependent Claims (13, 14, 15, 16, 17)

18. A system, comprising:
-
a Wireless Fidelity Personal Area Networks (WiFi PAN) master; at least one mobile node (MN) configured for heterogeneous secure associations with said PAN master; wherein said at least one MN is designated as a regular mobile node (MN) if it establishes a security association with said PAN Master as it advertised by said PAN Master or designated as an outstanding MN if it establishes a security association which differs from that advertised by said PAN Master; and wherein said PAN Master differentiates between subscribed and not subscribed multicast packets and if a currently processed frame is sent to a subscribed multicast address and both a Regular MN and an Outstanding MN are subscribed to said multicast address, then said PAN Master will convert the frame to unicast and will send to each subscribed Outstanding MN using its unicast security model, wherein said MN and said Master are implemented in hardware or a combination of hardware and software. - View Dependent Claims (19, 20, 21)
