Research on Secure Job Process and Implementation Technologies of Engineering Computational Service Grid Portal

Engineering Computational Service Grid Portal (ECSGP) is an engineering computational environment for integrating design resources effectively by using Grid portal technology. For ECSGP, the secure job process by integrating proxy credential, authentication trust level, and secure BPEL(Business Process Execution Language) engine is proposed, and the implementation technologies are analyzed in this paper. The research results in this paper provide the basis for constructing ECSGP.
