A Service-oriented Secure Infrastructure for Feature-based Data Exchange in Cloud-based Design and Manufacture

Under the impact of service-oriented architecture (SOA) and cloud computing, Cloud-Based Design and Manufacture (CBDM) has been a flexible and effective way for Collaborative Product Development (CPD). As a crucial issue in sharing CAD models for CPD, Feature-Based Data Exchange (FBDE) among heterogeneous CAD systems should be adapted in CBDM. On the other hand, the sensitive information and intellectual property of CAD models should be protected in the process of FBDE and CBDM. This paper presents a service-oriented architecture for secure FBDE in CBDM. This architecture replaces traditional data exchange and secure process, which are based on client sides, with a service-oriented data exchange and secure process on clouds. In this way, feature-based CAD models could be exchanged among collaborative designers with the sensitive information protected in CBDM. The service-oriented infrastructure provides cost-effective, flexible and scalable solutions for secure FBDE. The case study and experiments demonstrate the proposed idea and method.
