In traditional systems a secure element (the \"dongle\") is used to protect software. However, this approach suffers from several technical and economical drawbacks such as the dongle being lost or broken. We present a system that provides such dongles as a cloud service, and more importantly, provides the required cryptographic material to control access to software functionality in real-time. This system is developed as part of an ongoing nationally funded research project and is now entering a first trial stage with stakeholders from different industrial sectors.}, language = {en} }
