摘 要：提出了一种新的与PDM集成的协同设计环境中的产品数据安全模型。该安全模型通过用户登录模块、用户管理模块、访问控制管理模块、协同冲突机制模块、审计日志模块等来解决与PDM集成的协同设计环境中的产品数据的安全问题，并在此基础上引入了数据加/解密技术。研究结果表明，该模型可以有效地应用于与PDM集成的协同设计环境中，解决产品数据在设计过程中的安全问题。

Abstract: A new security model of product data in computer supported collaborative design integrated with PDM was presented. The new security model was realized by several methods which are user login, user and access control management, collaborative collision mechanism, audit record ，also import encryption and decryption of the product data. The research results show that the model can be effectively applied in the computer supported collaborative design integrated with PDM and solves the problem of data security.
Key words: computer supported collaborative design; product data; security model
