面向语义Web的基于语义和上下文的访问控制模型

Context-aware semantic-based access control model for semantic Web

对语义Web上资源的访问需要授权决策充分考虑其中实体之间的语义关系和上下文因素,而传统的访问控制模型不能处理这些问题。结合基于本体的语义描述技术和基于SWRL规则的推理机制,并将不同的语义关系归纳为一种包含关系,提出了一种面向语义Web的基于语义和上下文的访问控制(CSBAC)模型,并讨论了其语义授权推理、授权传播及冲突解决和实现架构。

The access decision should take into account the semantic relationships among entities and contexts under this environment when accessing to resources on the semantic Web, but traditional access control models fail to do it. By combining Ontology-based semantic representation technology with SWRL rule-based reasoning mechanism, and reducing different semantic interrelations to the subsumption relation, a Context-aware Semantic-based Access Control （CSBAC） model for the semantic Web was presented, and its semantic authorization inference, authorization propagation and conflict resolution were discussed. In the end, a structure for implementing the CSBAC model was proposed.
