There is a TinySec in TinyOS to provide integrity and confidentiality in wireless sensor network (WSN). However, the TinySec is operated based on simple group key management; this is not enough to ensure sensor node security. Accordingly, we propose a new access control methodology using task-role based access control (T-RBAC) which has been successfully applied to many different kinds of security...
