Abstract:
This paper analyzes desires of dynamic group key managerment oriented to vitual organization in grid computing system, investigates the four layers architecture of the VO based on selective environment by members in VO and the policy of member admission, and gives a layered distributed key protocol which appropriate to the VO of four layers architecture, the protocol can avoid the abuse of the centralized distribution and the single-point failure exists in the management pattern, also possesses the benefit of layered architecture.

摘要: 分析了网格计算系统中面向虚拟组织的动态组密钥管理需求,讨论了基于虚拟组织成员选择环境的“虚拟组织4层结构”和“成员加入策略”,给出了分层分布式密钥协议,避免在密钥的集中式分发与管理模式中,出现单点失败的情况,并具有了层次结构的优点。
