Towards Trust Management-based Detection in Internet of Things

With the tremendous development of Internet of Things (IoT), many security concerns have been raised. For protection, detection mechanisms like intrusion detection system (IDS) are moving into a collaborative mode. However, due to the distributed nature, insider threats are a big challenge that can compromise the detection performance and efficiency in IoT environments. Hence there is a great need to design appropriate trust management mechanisms to help enhance the effectiveness of detection mechanisms. This talk will introduce the background of intrusion detection in IoT networks, discuss the state-of-the-art on how to combine trust management with collaborative detection, and share the vision regarding how to build robust collaborative intrusion detection under large-scale IoT networks.
