The complexity and distinct management of our interconnected infrastructures makes their understanding and protection schemes very difficult. It is necessary to develop tools that represent the actual infrastructure and its dependencies on other infrastructures in order to assist infrastructure deployment, management, and assessment. However, even though it is necessary to share internal infrastructure information to model dependencies, operators, who often compete on the same market, are not willing to do so. In this paper, we propose a framework for an infrastructure simulator that gathers dependency information on a virtual market and assess the relevance of the information using dynamic trust models. We argue that a virtual market has the ability to motivate stakeholders to share information that can then be used in an internal simulator modelling dependencies.
