一种高效的制造网格认证模型设计

An Efficient Design of Authentication Model in Manufacturing Grid

针对制造网格的组织结构和工作流程复杂,传统的基于Globus的GSI认证机制在制造网格中的认证效率低下,从而降低整个网格资源的利用率的问题;提出一种改进的GSI认证模型,将用户证书和代理证书申请和签署集成在网格Portal上,在原有网格Portal服务器上部署CA认证模块,并增加MyProxy服务器,存储用户的个人证书和用户映射表,在其上部署代理证书签署模块;用户通过认证后即可提交任务、访问跨域资源,提高了制造网格的认证效率。

The business processes and organization of Manufacturing Grid（MG） are complicated.The traditional GSI authentication mechanism based on Globus is inefficient,which reduces the whole utilization ratio of grid resources.An efficient GSI authentication model which integrated user certificate and proxy certificate on grid portal is presented in the paper.It integrates user certificate and proxy certificate in grid portal,deploys CA authentication on used portal server.It also increases MyProxy server which stores personal certificate and user mapping,deploys proxy certificate signed module.The model improves the authentication efficiency of MG,and users can access cross-domain resources after being authenticated.
