In secure group communication model users in the group communicate among themselves securely. A group key is used to provide security for the messages. Some applications like pay-per-view, periodical electronic information distribution etc., are relied on secure group communication model, many users join and leave the group at the same moment known as bursty behavior. In this paper we propose a scheme for handling bursty behavior. We use binomial key tree for managing the secure group, which is quite efficient in handling rekeying strategies. We show that our scheme is efficient by comparing with other existing schemes.
