基于信任域的网格认证模型
Trust domain-based authentieation model in grid
-
摘要: 针对现有网格认证模型中PKI认证过程过于繁琐,建设和维护成本高以及IBC认证存在密钥托管的问题.研究了域内和域间资源提供者和资源请求者间的行为信任关系,利用该信任关系,在现有的组合PKI和IBC认证模型中引入临时信任域的概念,设计了基于信任域的网格认证模型.仿真实验表明,该模型具有较低的通信量和较短的认证时间.Abstract: Aimed at the problems that PKI authentication process is too onerous,construction and maintenance costs are high,and there is key escrow in IBC certification model in the existing grid authentication model,the behavior trust relationship between the resource providers and resource requester in the intra-and inter-domain was studied.We make use of the trust relationship to introduce the concept of temporary trust domain in the combination of the existing PKI and IBC certification model.The grid authentiation model based on the trust domain was designed.Simulation results showed that the model had low traffic and shorter authentieation time.
