A Generalized Associated Temporal and Spatial Role-Based Access Control Model for Wireless Heterogeneous Networks

[[abstract]]To securely access data center supporting the constraint of temporal and location-based services, access-control system requires more flexible definitions applying to Wireless Heterogeneous Networks (WHNs). To cope with the WHNs environment, we propose an Associated Temporal and Spatial Role-based Access Control (ATSRBAC) model. In this model, both temporal-period and spatial-location based entities are used to constrain the permissions of objects, user positions, and geographically bounded roles within associated wireless time-bound database (WTD) servers. In this paper, we also present temporal and spatial-based relations of associated RH, associated time and spatial SSD and associated time and spatial DSD constraints in the ATSRBAC model
