A Semantic-based Access Control Mechanism Using Semantic Technologies

摘要

In order to overcome the shortcomings of the recent frameworks and mechanisms for semantic-based access control, this paper presents a semantic-based, context-aware, and multi-domain enabled framework implementing a semantic-based access control mechanism for Semantic Web. The access control framework is based on the MA(DL)~2 model, which takes the semantic relationships among different entities into account. The framework handles the Semantic Web context by classifying and representing it through an ontology. Considering the MA(DL)~2 model, the framework assumes Semantic Web having some overlapped domains, which each contains an authority and a security agent. As a domain authority responsibility is to specify the domain policies, its agent is to enforce them. The mechanism is designed using the semantic technologies, which make it fully consistent with the environment. The paper clarifies the usability of the designed mechanism through some examples of an elections system case study.
