The Internet of Things (IoT) will connect a large number of communication and information systems. These systems will be part of everyday life in the same way mobile phones have become part of our lives. The information security properties of the IoT are often difficult to understand for its users, because they are hidden in pervasive systems and small devices manufactured by a large number of vendors. Trustworthiness, security functions and privacy implications are vast, and must be assessable to users and consumers.The main focus of the uTRUSTit project lies in its objective to integrate the user directly in the trust chain, guaranteeing transparency in the underlying security and reliability properties of the IoT. The results of uTRUSTit enable system manufacturers and system integrators to express the underlying security concepts to users in a comprehensible way, allowing them to make valid judgements on the trustworthiness of such systems. Further, uTRUSTit's design guidelines on trust help the industry to implement the trust-feedback toolkit developed by uTRUSTit in a secure, usable and accessible way.The uTRUSTit project will develop a cognitive model of user trust perception, its requirements, and its complete evaluation in simulation and end user trials.The problem area will be approached with interdisciplinary requirements engineering, the extension of usability methodology, simulation of IoT environments in virtual reality, and rapid prototyping of IoT environments for end-user testing in usability labs.The uTRUSTit consortium is composed of experienced security researchers, practitioners, and simulation and usability laboratories from different parts of Europe. It provides the expertise and experience needed to successfully solve the challenges of trust in the IoT.
