摘要
多播作为一种能够有效利用网络带宽、提高通信效率的通信机制,正在广泛地被应用于多个领域。传统组播缺乏细粒度的访问控制机制,这给组播的安全及性能带来许多隐患。本文在主动组播的基础上提出一种基于信任管理的访问控制机制,并在此基础上给出了Keynote信任管理系统在安全主动组播中的应用构架。该构架能较好解决传统IP组播中未能解决的组播组成员的访问控制与分布式授权问题,从而提高了IP组播的安全性。
As an effective net wide and a mechanism which improves communication capacity, multicast now is being applied in many fields. However, traditional muhicast lacks the detailed filter precision in visit control mechanism, which brings safety problems to muhicast. Thus, on the base of active muhicast, this thesis proposes a visit control mechanism that is founded on trust management, and suggests the application structure of Keynote trust management system in active multicast. This structure can solve the problem, which exists in multicast members＇ visit control and delivering authorization of traditional IP multicast.
