To build multicast scheme satisfying
Group member outside the coverage area
Group member inside the coverage area
Shared Wireless Channel
Coverage area of base station
Range of base station
Malicious node outside coverage area but inside the range of base station
The key establishment algorithm
Session Key is unique for each of the multicast group receivers.
Session Key is common for all the multicast group receivers.
Session Key is common for a subset of the multicast group receivers and unique keys are used for the remainder members.
The requests for re-keying are aggregated over a period of time and then processed. The batch interval is parameter
When a node new node enters we use the old key to multicast the new key to the older members
