Abstract
In order to protect the sensitive information in collaborative manufacturing grid environment, an access control solution was proposed to satisfy the inherent dynamic natures of the Manufacturing Grid, including dynamic Business Flow and system environment. In this solution, the Manufacturing Context-Aware Grid Access Control (MG_TC-RBAC) model extended the Role based Access Control (RBAC) model, activity is used to encapsulate user's role and relevant permission, and the user's permission is accurate by task and environment context. This model can be used as a reference basis for the Manufacturing Grid security problem.
