چكيده فارسي :
This paper proposes an efficient many-to-many
group key management protocol in distributed group
communication. In this protocol, group members are managed in
the hierarchical manner logically. Two kinds of keys are used,
asymmetric and symmetric keys. The leaf nodes in the key tree
are the asymmetric keys of the corresponding group members
and all the intermediate node keys are symmetric keys assigned
to each intermediate node. For asymmetric key, Diffie-Hellman
key agreement is introduced. To calculate intermediate node keys,
members use codes assigned to each intermediate node key tree.
Group members calculate intermediate node keys rather than
distributed by a sponsor member. The features of this approach
are that, no keys are exchanged between existing members at join,
and only one key, the group key, is delivered to remaining
members at leave.
