A group communication benefits from IP multicast to achieve to scalable exchange of messages. IP multicast itself does not provide any mechanism for preventing non group members to have access to the group communication. Although encryption can be used to protect messages exchanged among group members. There are different approaches to group key management these approaches can the authors divided into three main classes: centralized group key management protocols, decentralized architectures and distributed key management protocols.
