摘　　要：Multicast is an internet service that provides efficient data delivery from a source to multiple receivers. It greatly reduces the network bandwidth requirements and the host devices transmission overhead. This makes multicast an ideal technology for communication among a large group of participants. Secure multicast communication involves many services including teleconferencing, pay-TV and real-time delivery of stock quotes. One of the important challenges for multicast communication is to design secure and efficient group key management. In this paper, we propose two efficient selective-identity based multicast schemes. They have distinct advantages over the existing schemes in the sense of dynamic group key management. Our schemes satisfy forward secrecy and backward secrecy. Moreover, in our schemes, the member can be stateless receiver, who does not need to update his/her state from session to session.
