| 摘 要： | 针对应用层多播的特点,提出一种基于角色和上下文的访问控制模型(DRBAC),从而实现对组播系统进行动态的权限分配.该方案以DRBAC数据库为核心,以组成员的上下文信息为配置条件,动态地给组成员授权.不仅能动态指派角色,而且能灵活地维护配置权限,适用于组成员复杂且频繁更新的大规模应用层多播系统,这样能有效提高应用层多播的访问控制性能. |

| Abstract: | 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.... |
