Abstract

There is a TinySec in TinyOS to provide integrity and confidentiality of message for Wireless Sensor Network (WSN). However, TinySec employs a simple group key management, so if a sensor node is compromised by an adversary, overall sensor nodes in the network are likely to be compromised. Therefore, we propose a new access control methodology for WSN, based on Task-Role Based Access Control (T-RBAC). T-RBAC has been successfully applied to many different kinds of security applications. T-RBAC has also capability to provide flexible authentication and authorization to the system. We present the design and implementation results on our approach, and we show security analysis and comparison results show the feasibility of our approach.
