Abstract

Abstract: A fine-grained access control model based on trust is proposed in that the fine grit of traditional role access control model is not compatible and the model also introduces authorized trust constrain on the basis of RBAC, which effectively prevents malicious behavior and realizes trust computing method based on loyalty owing to the adoption of computing method based on loyalty. So not only does the model have the advantages of all RBAC model but also it is much more accessible, flexible and extensible than RBAC model.

Key words: trust, fine-grained, loyalty, access control

摘要： 针对传统的角色访问控制模型权限控制粒度较大，提出一种基于信任的细粒度访问控制模型，该模型在RBAC基础上引入授权信任约束，采用了一种基于忠诚度的信任度计算方法，有效地遏制恶意行为，实现细粒度访问控制。该模型不仅具有RBAC模型的所有优点，而且比RBAC模型具有更好的通用性、灵活性和可扩展性。
