WSNLab – a Security Testbed and Security Architecture for WSNs : Demo at the 36th IEEE Conference on Local Computer Networks

Abstract

There is a need for a real-world security testbed for the evaluation of WSN security measures and a security architecture for WSNs can be developed, implemented, and evaluated. A Wireless Sensor Network (WSN) consists of small, resource-constrained computing devices (so-called motes) that perform physical measurements (e.g., temperature, vibration) in a distributed manner. The motes form a self-adaptive multihop network to transport the measured data to a sink. The data may be pre-processed and fused in the network. Furthermore, WSNs often provide capabilities using a reverse channel for sensor control and management as well as flashing of motes and Over-The-Air Programming (OTAP). WSNs are deployed in a steadily growing plethora of application areas. Especially their deployment in the industrial, military, public safety, and medical domains renders security in these networks an issue of high relevance. There is a need for a real-world security testbed for the evaluation of WSN security measures. Given such a lab, a security architecture for WSN can be developed, implemented, and evaluated. The rest of this abstract is structured as follows: The testbed is described in Section II. Next, we present a threat analysis and security architecture for WSNs (Section III). In the demo, we will show our WSN testbed as well as the Intrusion Detection System (IDS).
