Abstract: The paper proposes an active-network-based secure multicast , which solves multicast security problems such as the privacy and integrity of data, authentication and management of senders. Besides, the use of active network technology provides the high flexibility , by which users can update the multicast software, adjust the group management of multicast at any time. So the technology proposed by the paper is characterized by security and flexibility.
