PDM中数据安全研究

The research about data security of PDM

以国家十五攻关项目“网络化制造平台”的子项目“网络化产品数据管理(PDM)”为支撑,研究PDM对内、对外的安全性。重点研究了数据加密技术和数字签名技术,并创造性地给出了混合加密和数字签名联合使用的实现策略,该策略已在数家制造企业实施PDM时所应用。

Mainly researched the data security of PDM and support by ' network data management (PDM) ' which was subproject of 'network manufacturing platform'. The internal security depended on privilege management & data encryption technologies & digital signature technologies. The strategy for mix encryption associating with digital signature had been brought forth which had been validated by PDM implementing in several manufacturing enterprise.
