Moving from traditional one-to-one to many-to-many communication, publish/subscribe systems promise a more dynamic and efficient exchange of data. However, the resulting significantly more complex communication relationships render traditional end-to-end security futile for sufficiently protecting the sensitive and safety-critical data transmitted in industrial systems. Most notably, the central message brokers inherent in publish/subscribe systems introduce a designated weak spot for security as they can access all communication messages. To address this issue, we propose ENTRUST, a novel solution for key server-based end-to-end security in publish/subscribe systems. ENTRUST transparently realizes confidentiality, integrity, and authentication for publish/subscribe systems without any modification of the underlying protocol. We exemplarily implement ENTRUST on top of MQTT, the de-facto standard for machine-to-machine communication, showing that ENTRUST can integrate seamlessly into existing publish/subscribe systems. cyber-physical system security; publish-subscribe security; end-to-end security internet-of-production https://www.comsys.rwth-aachen.de/fileadmin/papers/2021/2021-dahlmanns-entrust.pdf ACM Proceedings of the 1st ACM Workshop on Secure and Trustworthy Cyber-Physical Systems (SaT-CPS '21), co-located with the 11th ACM Conference on Data and Application Security and Privacy (CODASPY '21), April 26-28, 2021, Virtual Event, USA Virtual Event, USA ACM Workshop on Secure and Trustworthy Cyber-Physical Systems April 28, 2021 978-1-4503-8319-6/21/04 10.1145/3445969.3450423 1 MarkusDahlmanns JanPennekamp Ina BereniceFink BerndSchoolmann KlausWehrle MartinHenze
