Access Control Model of Manufacturing Grid
Hongxia Cai, Tao Yu, Minglun Fang · 2006
The overall motivation for Manufacturing Grid is to realize resource sharing and collaboration in the field of Manufacturing. In order to protect the shared resources and services, the access control guarantees in the MG is necessary and important. Due to inherent heterogeneity, multi-domain characteristic and highly dynamic nature of Manufacturing Grid, we propose a new Manufacturing Grid Access Control Model to support the dynamic restricted rights management based on the current Role-based Access Control Model. We employ a distributed access control mechanism to realize the authorization from the local service nodes according to the global and local authorization policy. The implementation within the project of the Shanghai High Institutions Grid proves the authorization architecture and model are workable and our work is valuable.
