Abstract: This paper presents a secure framework for dispatching and completing tasks in a network of weak embedded devices, such as sensors. The framework allows a device to dispatch tasks to other remote devices so that the remote devices can utilise their idle resources to help the execution of the tasks. The framework also ensures that the secure data of the originating devices will not be disclosed with the tasks that are dispatched to the helping devices. The framework is implemented with TinyOS and MICAz motes for evaluation. The results show that the framework achieves the desired security with little overhead and is feasible to weak devices.
