Model security for collaborative product design in a networked environment (or called networked manufacture, grid manufacture, and cloud manufacture) is an important but also challenging research issue. In order to support collaborative product design in a secure and flexible means, a partial encryption based secure sharing method for Computer Aided Design (CAD) model is presented in this paper. Based on the above method, parts of a CAD model can be selected flexibly by users for encrypting according to different users’ requirements. The secret keys for the different parts of the CAD model can be customized to meet the requirements of users. Case studies have been developed to demonstrate the effectiveness of the proposed method.
