摘　　要：针对网络化制造系统中产品设计文档流转的特殊安全需求,提出了基于PK I的文档安全解决方案。该方案采用对称加密技术保证设计图纸加解密的效率,通过数字信封技术实现对称密钥在多个用户之间的安全传输;将消隐数字签名技术应用于VRML格式文件中,实现了在不出示完整文档的情况下认证文档中的部分内容,解决了不可见性和完整性之间的矛盾。原型系统基于B/S模式和通用的VRML文件格式,具有良好的适应性和跨平台性。To meet the special security requirement for the transmission of product design documents in networked manufacturing systems, a secure scheme was proposed based on PKI. The scheme adopted symmetric encryption technology to assure the efficiency of the encryption and decryption of the design drawing, and realized safe transmission of the symmetric key among multiple users by digital-envelop technology; the sanitizable digital signature technology was used for documents in VRML format to realize the authentication of partial file without the whole file being demonstrated, by which the contradiction between invisibility and integrity was overcame. The system based on B/S mode and the general VRML format has good cross- platform adaptability.
