Architectural Patterns for Secure IoT Orchestrations

The vast amount of connected devices on the Internet of Things (IoT) creates an enormous potential for new applications, by leveraging synergies arising through the convergence of consumer, business and industrial Internet, and creating open, global networks connecting people, data, and "things". In this context, the SEMIoTICS project aims to develop a pattern-driven framework, built upon existing IoT platforms, to enable and guarantee secure and dependable actuation and semi-autonomic behaviour in IoT/Industrial IoT applications. To achieve this, patterns are used to encode proven dependencies between the security, privacy, dependability and interoperability (SPDI) properties of individual smart objects and corresponding properties of orchestrations (composition) involving them. This paper sketches this approach followed by SEMIoTICS, whereby the SPDI patterns are used to generate IoT orchestrations with proven SPDI properties at design time, while at runtime these properties are monitored in real-time, across system layers, triggering adaptations to return the deployed orchestration to the desired SPDI state, when needed.
