With the growing interconnections in the Internet of things (IoT), secure communication is an increasing challenge. Within SIMPL a special solution for secure communication will be developed, tailored to the needs of loosely coupled devices in the IoT. SIMPL shall be independent of the utilized communication middleware to avoid a vendor lock-in at a platform as a service provider and to enable parallel operation of secure and insecure communication. This allows the systems to be extended and migrated step by step.

The goal of SIMPL is to realize a security solution for IoT systems that contains the following innovations:

  • As a security overlay, SIMPL allows to keep the existing event-based middleware without changes.
  • The high dynamics of IoT systems with changing communication partners are taken into account.
  • SIMPL supports especially mobile devices with limited resources, which are common in IoT applications.

To reach these goals, existing security techniques are examined regarding their applicability and integrated into the SIMPL system. A management instance responsible for the IoT system performs the dynamic configuration and monitoring independently of the used middleware. The developed concepts are implemented in a feasibility study and subsequently demonstrated and evaluated for different use cases.
