摘　　要：供应链中实体间关系的动态性、交叉性、多变性和复杂性为供应链中RFID数据及关联信息的安全访问带来了巨大的挑战。在分析实体和实体、用户和实体之间关系的基础上,综合多种信息访问控制模型,提出了一种适合于数字供应链的RFID数据及关联信息的复合访问控制模型,设计了一种信息访问控制的授权规范,建立了一种关系以实现从用户到信息访问权限的映射,给出了用户对信息访问权限的判断流程。结合关系型数据库和工作流引擎,给出了该复合访问控制模型的实现方法。The dynamic, crossover,versatility and complex relation among entities in a supply chain brings great challenges for the access control of RFID data and related information. Based on the analysis of relation between entities, user and entities, a composite access control model for the RFID data and related information in digital supply chain was presented, which combines some of the existed access models. An authorization specification for information access was designed, the map between user and information access authorization is established~ and the workflow to decide whether a use can access some information is given. An implementation for such composite access control model is given based on relational database and workflow engine.
