ACM Distinguished Paper Award for Fault Tolerant Systems Research Group members

October 14, 2016

Gábor Bergmann, Csaba Debreceni, István Ráth and Dániel Varró from the Fault Tolerant Systems Research Group received the ACM Distinguished Paper Award for their paper, entitled Query-based Access Control for Secure Collaborative Modeling using Bidirectional Transformations, at MODELS 2016 (ACM/IEEE Model Driven Engineering Languages and Systems) conference. MODELS is the premier conference series for model-based software and systems engineering which since 1998 has been covering all aspects of modeling, from languages and methods to tools and applications.

In large-scale model-driven system engineering projects several engineers with different areas of expertise have to work together, often in a multi-organizational collaboration, which raises a number of security questions. The paper proposes a new approach that allows for more granular, precise and flexible ways of access control than what was previously possible. A prototype tool demonstrates that such a service can be seamlessly integrated into existing tools and traditional collaboration workflows, while also providing efficient support for web-based simultaneous online model editing.
