Study on Light-Weight Secured Model for Wireless Sensor Network Based on RBAC

A RBAC(role based access control) model is extended to TinyRBAC which is a light-weight secured model for wireless sensor network in TinyOS. First the core module, role hierarchy and restricted mechanism of the TinyRBAC are described and defined; Through the analysis and experiments, the secure targets and performance are evaluated. The result shows that the TinyRABC is feasible and useful for wireless sensor network.
