Research of DRBAC-based privilege management in application layer multicast
Wang Xia · Journal of Foshan University · 2009
Based on the characteristics of Application Layer Multicast,this paper proposes a DRABC model-based scheme,which can manage the privilege of multicast system dynamically.This scheme is based on DRBAC database and group member's context information,authorizes the group member dynamically.It can not only assign roles to the group members dynamically,but also maintain the allocated privilege flexibly.It can be applied to large-scale frequent updated application-layer multicast system which has complex members.By this means it can effectively improve the application layer multicast access control performance.
