Institut für Verteilte Systeme

Unser Institut beschäftigt sich mit Themen wie Skalierbarkeit, Zuverlässigkeit, Sicherheit und Datenschutz, Selbstorganisation und Beherrschbarkeit von Komplexität in Verteilten Systemen in einer Vielzahl von Einsatzszenarien wie Cloud-Computing oder Fahrzeug-Fahrzeug-Kommunikation.

In der Lehre decken wir das gesamte Spektrum von Rechnernetzen, über verteilte Systeme bis hin zu Sicherheit und Privacy-Schutz ab.

Chronograph – A Distributed Processing Platform for Online and Batch Computations on Event-sourced Graphs
Proceedings of the 11th ACM International Conference on Distributed Event-Based Systems

Zusammenfassung: Several data-intensive applications take streams of events as a continuous input and internally map events onto a dynamic, graph-based data model which is then used for processing. The differences between event processing, graph computing, as well as batch processing and near-realtime processing yield a number of specific requirements for computing platforms that try to unify theses approaches. By combining an altered actor model, an event-sourced persistence layer, and a vertex-based, asynchronous programming model, we propose a distributed computing platform that supports event-driven, graph-based applications in a single platform. Our Chronograph platform concept enables online and offline computations on event-driven, history-aware graphs and supports different processing models on the evolving graph.

A Testing Framework Architecture Concept for Automotive Intrusion Detection Systems
Proceedings of Automotive - Safety and Security 2017
Mai 2017

Zusammenfassung: Vehicles are the target of a rising number of hacking attacks. The integration of in-vehicle intrusion detection systems is a common approach to increase the overall system security. However, testing and evaluating these systems is difficult due to the lack of tools to generate realistic benign and malicious workloads as well as sharing these workloads with other researchers. Currently, test- ing tools are predominantly intended for Network Intrusion Detection System (NIDS) in company or industrial networks where their usefulness became apparent. Yet, in the automotive domain, develop- ment of testing tools is still in the early stages. Existing non-commercial automotive tools only focus on one specific bus technology each. However, in-vehicle communication exceeds bus technology boundaries and a testing tool must cover multiple technologies. We propose a framework architec- ture concept for in-vehicle NIDS testing and evaluation to enable the creation of realistic network traffic and attacks in consideration of automotive specific challenges. Our concept provides the op- portunity to share data without additional anonymization effort therefore improving cooperation and reproducibility of testing results.
