Dispute Resolution for Smart Contract-based Two-Party Protocols
- Eric Wagner, Achim Völker, Frederik Fuhrmann, Roman Matzutt, Klaus Wehrle
- Computer Science, MathematicsInternational Conference on Blockchain
- 14 May 2019
SmartJudge is introduced, an extensible generalization of this trend for smart contract-based two-party protocols that relies on a protocol-independent mediator smart contract that moderates two- party interactions and only consults protocol-specific verifier smart contracts in case of a dispute.
Secure Low Latency Communication for Constrained Industrial IoT Scenarios
- Jens Hiller, Martin Henze, Martin Serror, Eric Wagner, Jan Niklas Richter, Klaus Wehrle
- Computer ScienceIEEE Conference on Local Computer Networks
- 1 October 2018
It is shown that antedated encryption and data authentication with templates enables IoT devices to meet both, security and low latency requirements and offload significant security processing to a preprocessing phase and thus decrease latency during actual transmission by up to 75.9 %.
QWIN: Facilitating QoS in Wireless Industrial Networks Through Cooperation
- Martin Serror, Eric Wagner, René Glebke, Klaus Wehrle
- Computer ScienceIFIP Networking Conference (Networking)
- 1 June 2020
QWIN is investigated, a novel approach that leverages this cooperative nature of industrial scenarios by enabling the stations to share the scarce transmission resources by offload their priority queues into the network and share them according to the quality-of-service requirements imposed by the overlying industrial applications.
IPAL: Breaking up Silos of Protocol-dependent and Domain-specific Industrial Intrusion Detection Systems
- Konrad Wolsing, Eric Wagner, Antoine Saillard, Martin Henze
- Computer ScienceInternational Symposium on Recent Advances in…
- 5 November 2021
This work proposes IPAL, the authors' industrial protocol abstraction layer, to decouple intrusion detection from domain-specific industrial protocols, and proves IPAL’s correctness in a reproducibility study of related work, and showcases its unique benefits by studying the generalizability of existing approaches to new datasets.
A False Sense of Security?: Revisiting the State of Machine Learning-Based Industrial Intrusion Detection
- Dominik Kus, Eric Wagner, Martin Henze
- Computer ScienceCPSS@AsiaCCS
- 18 May 2022
An evaluation methodology is developed and multiple approaches from literature are examined for their performance on unknown attacks, highlighting an ineffectiveness in detecting unknown attacks.

Take a Bite of the Reality Sandwich: Revisiting the Security of Progressive Message Authentication Codes
- Eric Wagner, Jan Bauer, Martin Henze
- Computer ScienceWireless Network Security
- 15 March 2021
SP-MAC is introduced, which implements R2-D2, which uses randomized dependencies with parameterized security guarantees to increase the resilience of progressive authentication against packet loss and is resilient to sophisticated network-level attacks.
PowerDuck: A GOOSE Data Set of Cyberattacks in Substations
- Sven Zemanek, I. Hacker, Konrad Wolsing, Eric Wagner, Martin Henze, Martin Serror
- Computer ScienceCSET @ USENIX Security Symposium
- 11 July 2022
PowerDuck is presented, a publicly available security data set containing network traces of GOOSE communication in a physical substation testbed, which envision PowerDuck improving and complementing existing data sets of substations, which are often generated synthetically, thus enhancing the security of power grids.
