| 随着因特网用户的急剧增加和因特网不断的商业化,多播技术呈现出极为广阔的应用领域.在国际上,多播是一个崭新的学术研究领域,主要的研究成果集中在多播的路由算法、流量控制、拥塞控制和可靠传输上,多播安全领域的研究成果相对较少(尤其是在组通信密钥管理方面).研究了多播安全机制中的组通信密钥管理和访问控制问题.提出了一种基于子组安全控制器的组通信密钥管理和访问控制方案,该安全方案改进并解决了IOLUS系统和WGL方案中存在的若干问题,简化了访问控制策略,达到了预期的设计目标和要求. |

| Abstract: |
| As the process of proliferation of the Internet progresses and multicast applications are deployed for mainstream use, the need to IP multicasting technology will become critical. Now, the research of multicast technology has become a fresh new thriving academic field. Many main results converge to such fields as the multicast routing, the flow control, the congestion control and reliable multicast. But the results referred to multicast security are very few (especially in the field of group key management).In this paper,the problems of group key management and access control for large dynamic multicast groups have been researched.A scheme based on subgroup secure controllers are proposed which solves many problems of the Iolus System and the solution of WGL, and at the same time,which simplifies the scheme of access control and meets our design aims and requirements. |
