Abstract
Manufacturing grid consists of a collection of heterogeneous resources across multiple administrative domains with the intent of providing enterprises to realize resource sharing and collaboration. A comprehensive set of manufacturing grid usage scenarios is presented and analyzed with regard to security requirements such as authentication, authorization, integrity, nonrepudition and confidentiality. The main value of these scenarios is to increase the awareness of security issues in manufacturing grid which are different from computational grid. We take the unique security requirements of manufacturing grid into consideration and design a corresponding security solution. The implementation within the project of SMVPN (Shanghai Manufacturing Virtual Private Network) proves that the solution is workable and valuable.
