基于信任管理引擎的信任管理模型,提出了信任管理是信任意向的获取、评估和实施的新定义,并应用于已有的一个新型网格安全信任体系架构(NGST)中,将网格环境划分为多个自治域,每个自治域由一个信任代理处理本域所有信任关系的问题.在此环境下建立了域内信任管理模型,给出了安全性的形式分析与证明,利用凭证访问策略来保护协商双方的安全凭证中的敏感信息.结果表明,本文提出的信任管理模型是安全的,具备很好的自治性,并且能有效地将不良行为较多实体逐出自治域.
Based on the trust management model of trust management engine, trust management is proposed as a new definition of trust intentional acquisition, evaluation and implementation, and applied to a new type of grid security trust architecture (NGST) For multiple autonomous domains, each autonomous domain has a trusted agent to handle all the trust relationships in the domain.In this environment, an intra-domain trust management model is established, the formal analysis and proof of security is given, and the credential access policy is used The results show that the trust management model proposed in this paper is secure, has good autonomy, and effectively excludes more entities with bad behaviors from the autonomous domain.
