摘　　要：针对制造业多企业联盟的业务协作特性和信息资源被非授权的用户使用所带来的访问控制问题,提出一种基于属性的云制造协同平台访问控制模型。首先对访问请求和策略判定进行了形式化定义,然后给出了所提模型的策略判定案例、实施框架及应用方案。通过案例和应用方案可知,该模型不但可实现对协同业务进行动态和细粒度的授权,而且提高了云制造协同平台的灵活性、可扩展性和安全性。Aiming at the problem of access control brought by characteristic of collaborative business and unauthorized use of information resources for manufacturing multi-enterprise alliance,an access control model for attribute-based cloud manufacturing collaboration platform was proposed.The formalized definition of access request and policy decision was given,and a decision case based on policy,implementation framework and application scheme of proposed model were presented.Through the proposed case and scheme,model not only had achieved the authorization of collaborative business from dynamic and fine-grained perspectives,but also had improved the flexibility,scalability and security of cloud manufacturing collaborative platform.
