IP Packets between MN -- CN
The Idea – to hide the relation among HoAm, CoAm and CN

Packets from MN to CN
PKT’ = {CoAm’, CN, HoAm, payload} (3)
where
CoAm’ = (Prefix of CoAm) | (Interface of CoAm Å k’) (4)
(64 bits) (64 bits)
k’ = Hash( km | 0 ) (5)

Packets from CN to MN
PKT” = {CNm”, CoA, HoAm, payload} (6)
where
CNm’ = (Prefix of CN) | (Interface of CN Å k”) (7)
(64 bits) (64 bits)
k” = Hash( km | 1 ) (8)
