Wu Zheng Xiao · Information Security and Communications Privacy · 2007
In order to manage members of secure multicast, this paper proposes a centralized warrant scheme. The scheme sets a warrant table by a group controller, each record of warrant table defining a secure group. After group controller partitioning all members into different secure group, members can communicate securely with other members in same secure group. It can support forward confidentiality, backward confidentiality and anti-allied attack by dynamically updating warrant table and secure group.
