An Attribute-Based Extended Delegation Model 基于属性的扩展委托模型
This model supports dynamic and distributed attribute-based resource query, and it can be argued that this model has excellent scalability. 该模型支持基于属性的动态分布式查找,并且具有很好的扩展性。
Then an Attribute-based access control ( ABAC) model is proposed, which adopted the authorization mechanism dynamically and fine-grained based on subject, resource and environment attributes. 接着论文提出了一种基于属性的访问控制模型(ABAC),它基于主体、客体和环境的属性,采用动态的、细粒度的机制进行授权。
By combining the techniques of attribute based cryptosystem, we provided a totally new Attribute-Base Access Control model. It is extended from an attribute-based encrypt scheme of selection tree CPA security under standard model. 本文结合属性基密码的特性,提出了一种全新的基于属性的访问控制模型,它是由一个在标准模型下选择树CPA安全的属性基加密方案改进而来。
