Abstract:

  The challenges posed by the Internet of Things (IoT) render existing security measures ineffective against emerging networks and devices. These challenges include heterogeneity, operation in open environments, and scalability. We propose SST (Secure Swarm Toolkit), an open-source toolkit for construction and deployment of an authorization service infrastructure for the IoT. The infrastructure uses locally centralized, globally distributed authorization entities, which provide authorization services that can address heterogeneous security requirements and resource constraints in the IoT. The authorization services can be accessed by network entities through software interfaces provided by the SST infrastructure, called accessors. The accessors enable IoT developers to readily integrate their devices with authorization services without needing to manage cryptographic keys and operations. To rigorously show that SST provides necessary security guarantees, we have performed a formal security analysis using an automated verification tool. In addition, we demonstrate the scalability of our approach with a mathematical analysis, as well as experiments to evaluate security overhead of network entities under different security profiles supported by SST.
