Research on the Security of BPEL Based Manufacturing Service Workflow Management System

The security of BPEL (Business Process Execution Language) based manufacturing service workflow management system is researched in this paper, in order to achieve the efficient and secure integration and sharing of dispersed and heterogeneous design/manufacturing resources, and to realize the reuse of the complex distributed Design/Manufacturing process models. By integrating the secure BPEL engine, proxy credential server and authentication trust level, the security framework of the BPEL based manufacturing service workflow management system is built up, and the security mechanism of integrating BPEL and WSRF (Web Service Resource Framework) is analyzed. In addition, the system implementation technologies are analyzed and a distributed injection mould Design/Manufacturing application scenario is described. The research results provide the basis for developing a secure BPEL based distributed Design/Manufacturing prototype system.
