Abstract:
As an enabling technology or system integration framework, product data management (PDM) can manage the product-related information and process during the life cycle of manufacturing product in the range of whole enterprise. With the development of computer and network, PDM is applied in more enterprises. By studying the framework of PDM based on Intranet/Internet, this paper analyses the limitation of current PDM application software in security, proposes the method to build PDM security system, and discusses deeply how to keep security of data and process in PDM system. Some tools or methods about identity authentication, data encryption, digital signature, etc, which are used in PDM system, are described.
Key words:
