摘要

在网格中

组播是实现大规模信息资源共享的一种重要方式

然而

如何保障组播的安全性是一个十分复杂的问题.本文将以集中控制和分布式管理所采用的密钥管理策略为基础

在遵循网格组播机制的前提下

考虑成员动态变化因素

提出了分层方法、成员发现协议、分簇协议和密钥分配策略

从而形成了一种基于网格的安全组播密钥分配策略.仿真实验结果表明此密钥分配策略具有良好的可行性和有效性.

Abstract

In Grid

it is an important strategy that using multicast to realize the large-scale information resource sharing.However

it is very difficult to ensure the security of multicast.In this paper

based on the basic principles of the centralized key distributed strategy and the distributed key distribution strategy

according to the multicast mechanism in Grid

considering the dynamic factors of multicast members

we present the member hierarchy method for key distribution

the member discovery protocol

the clustering protocol and the key distribution strategy

thus constituting the key distribution strategy of security multicast in Grid.In order to validate the feasibility and the availability of this strategy

a simulation experiment is done.The results show that it is feasible and efficient to ensure the security multicast in Grid.
