Multicast is an internetwork group communication service which reduces the transmission overheads. The data can be secured by encrypting it with a group key, shared among all group members. Whenever members join/leave in a group communication, it is essential to preserve the forward and backward confidentiality by sending new keys for transmission. When members join/leave frequently, it gives rise to transmission overhead. Leasel is a multicast group communication model which addresses the problem of scalability due to the multicast transmission overheads. Being a de-centralized group model, a top ranking member of the sub-group is designated as a Leader and authorized to perform key generation and distribution.
