A security model based on relational model for semantic sensor networks

This paper proposes a novel security model for secure query processing in semantic sensor networks. A semantic sensor network (SSN) is a sensor network including semantics of sensory data and context information, and relationships between the semantics by using Semantic Web technologies. Even though much research has been activated on SSN, there is little activity on how to securely access data in semantic sensor networks. Most of storages have been developed based on relational database model and the relational database model provides a secure and robust security support. Therefore, we need to devise a security model considering such a real environment. This paper proposes a new access control model for secure query processing in semantic sensor networks. The proposed security model is based on relational database security model. This paper shows the overall framework and definitions of the proposal, and the experiment and evaluation is described to show validity of our proposal. With the experiment and evaluation, it is clear that the proposed model provides a secure access control support for SSNs.
