中文摘要: 着眼于CAD安全模型的创新，针对CAD文档保护系统的现状，分析并提出了目前CAD文档保护系统存在的问题，提出了一个以多层次动态权限策略为基础的CAD模型/文档保护算法。该算法通过对产品设计生命周期中不同角色在不同阶段的权限/行为分析，结合访问控制、权限管理、加解密技术等，实现了对CAD产品模型在整个产品设计周期内的安全控制。
Abstract:Based on the present situation of CAD document protection system, the paper focuses on the innovation of CAD security model. It analyses current problems and puts forward a CAD model protection algorithm whose basis is a multi-level and dynamic permission strategy. This algorithm allows different access permissions or operations to the CAD models while in different phases of the product life cycle. Combined with the technologies of Access Control, Permission Manage, Encryption and Decryption, the paper successfully makes the security control of the CAD model more reliable in its product life cycle.
