With the miniaturization of devices and development of network infrastructure, the use of Machine-to-Machine (M2M) or Internet of Things (IoT) services are becoming widespread. The arrival of M2M/IoT raises many questions such as how to suit the current computer security standard to IoT devices, how to accommodate the huge number of IoT devices, and how to meet the heterogonous requirements from a wide variety of devices. In this paper, we focus on the characteristics of IoT devices and propose a multi-level security support architecture for resource-constrained IoT devices without impairing security for resource-rich devices. We also discuss the comparison results from using a conventional uniform security support architecture.
