This research project focusses on extending an existing digital twin platform called DTaaS (Digital Twin as a Platform) with better support for secure collaboration between different legal entities. Digital twins are software representations of physical assets, processes, or systems. They leverage real-time data to mirror the behaviour and characteristics of their physical counterparts, enabling predictive maintenance, optimization, and improved decision-making in various industries like manufacturing, construction, and urban planning. Secure collaboration facilities in the DTaaS platform allows co-creation of products and services across multiple companies and authorities, thus supporting large virtual enterprises necessary for the development and operation of large-scale enterprises, such as critical infrastructures, logistics chains, etc.  

The research involves extensions to the DTaaS platform with multitenant security mechanisms that support definition and enforcement of security policies for multiple autonomous legal entities. A proof-of-concept of the value of such dynamic collaboration in a System of Systems setting is included with a case centred around Aarhus Festuge. Industrially this new technology is very valuable in order to protect the Intellectual Property for the different legal entities and principles for sharing data as the situation changes (using the security policies).
