| Abstract: | Current access control models applied in the network-based manufacturing system and application characteristics of collaborative project were analyzed. Based on these analyses, a role-based access control model was applied in collaborative environment. ARBCA97 was extended and activities in collaborative environment were combined with operations in role models. Mapping rules for activities in collaborative environment and operation in role models were introduced to guarantee authorization consistence in the event-sequence. Finally, the architecture and implementation mechanism of the model were also discussed. The proposed studies were applied in practical production with satisfactory results. |
