TY - CHAP U1 - Konferenzveröffentlichung A1 - Schaad, Andreas A1 - Grohmann, Björn A1 - Winzenried, Oliver T1 - CloudProtect - A Cloud-based Software Protection Service T2 - SACMAT '19: Proceedings of the 24th ACM Symposium on Access Control Models and Technologies N2 - Protecting software from illegal access, intentional modification or reverse engineering is an inherently difficult practical problem involving code obfuscation techniques and real-time cryptographic protection of code. 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.
