In recent years it has become more and more evident that the ability of systems to adapt themselves is an increasingly important requirement. This is not least driven by emerging computing trends like Ubiquitous Computing, Ambient Intelligence, and Cyber Physical Systems, where systems have to react on changing user needs, service/device availability and resource situations. Despite being open and adaptive it is a common requirement for such systems to be trustworthy, whereas traditional assurance techniques for related system properties like safety, reliability and security are not sufficient in this context. We recently developed the Plug&Safe approach for composition time safety assurance in systems of systems. In this position paper we provide an overview on Plug&Safe, elaborate the different facets of trust, and discuss how our approach can be augmented to enable trust assurance in open adaptive systems.
