Dependability arguments supported by fuzz-testing

Abstract

Today’s situation in operating theaters is characterized by many different devices from various manufacturers. Missing standards for device intercommunication lead to the fact that inter-device communication in most cases is either difficult or even impossible. A system oriented approach with networked devices is envisioned to improve this heterogeneous situation. Every device in the operating theater shall be able to interchange data with every other device in the network. Even remote control of other devices shall be possible. Therefore, concepts for safe and secure dynamic networking of components in operation theaters and hospitals have to be provided. This paper will show methods to test such systems of systems and provide a way to increase the robustness of the interfaces. This will be part of the evidence described in multidimensional dependability arguments provided to certification authorities.
