While electromagnetic attacks against radars can be carried out externally, primarily by military actors, research has recently shown that marine radar is also vulnerable to attacks from cyberspace. These can be carried out internally, less “loudly”, and with significantly less effort and know-how, thus posing a general threat to the shipping industry, the global maritime transport system, and world trade. Based on cyberattacks discussed in the scientific community and a simulation environment for marine radar systems, we investigate in this work to which extent existing Intrusion Detection System (IDS) solutions can secure vessels’ radar systems, how effective their detection capability is, and where their limits lie. From this, we derive a research gap for radar-specific methods and present the first two approaches in that direction.

While existing literature proposes effective IIDS solutions evaluated in controlled environments, their deployment in real-world industrial settings poses several challenges. This paper highlights two critical yet often overlooked aspects that significantly impact their practical deployment, i.e., the need for sufficient amounts of data to train the IIDS models and the challenges associated with finding suitable hyperparameters, especially for IIDSs training only on genuine ICS data. Through empirical experiments conducted on multiple state-of-the-art IIDSs and diverse datasets, we establish the criticality of these issues in deploying IIDSs. Our findings show the necessity of extensive malicious training data for supervised IIDSs, which can be impractical considering the complexity of recording and labeling attacks in actual industrial environments. Furthermore, while other IIDSs circumvent the previous issue by requiring only benign training data, these can suffer from the difficulty of setting appropriate hyperparameters, which likewise can diminish their performance. By shedding light on these challenges, we aim to enhance the understanding of the limitations and considerations necessary for deploying effective cybersecurity solutions in ICSs, which might be one reason why IIDSs see few deployments.}, keywords = {Industrial Intrusion Detection Systems, Cyber-Physical Systems, Industrial Control Systems, Deployment}, web_url = {https://arxiv.org/pdf/2403.01809}, publisher = {Springer}, booktitle = {Proceedings of the 10th Workshop on the Security of Industrial Control Systems \& of Cyber-Physical Systems (CyberICPS '24), co-located with the the 29th European Symposium on Research in Computer Security (ESORICS '24)}, event_place = {Bydgoszcz, Poland}, event_name = {10th Workshop on the Security of Industrial Control Systems \& of Cyber-Physical Systems (CyberICPS 2024)}, event_date = {September 16-20, 2024}, state = {accepted}, language = {English}, reviewed = {1}, author = {Wolsing, Konrad and Wagner, Eric and Basels, Frederik and Wagner, Patrick and Wehrle, Klaus} } @Inproceedings { 2024-dahlmanns-cired, title = {Reliable and Secure Control Center to Station Device Communication}, year = {2024}, month = {6}, day = {19}, abstract = {The increasing demands on the power grid require intelligent and flexible solutions that ensure the grid's stability.

To this end, IEC 61850 introduces data models which allow flexible communication. Still, the specification leaves open how DSOs should interconnect their stations to realize resilient communication between the control center and station devices. However, DSOs require such communication to adapt modern solutions increasing the grid's capacity, e.g., adaptive protection systems. In this paper, we present our envisioned network and communication concept for future DSO's ICT infrastructures that enables the control center to resiliently and flexibly communicate with station devices. For resilience, we suggest interconnecting each station with two distinct communication paths to the control center, use MPLS-TP and MPTCP for fast failovers when a single link fails, and mTLS to protect the communication possibilities against misuse.

This requirement contrasts with SDO policies that permit SEP holders to charge implementers monetary patent royalties, sometimes on terms that are specified as “fair, reasonable and nondiscriminatory” (FRAND). As demonstrated by two decades of intensive litigation around the world, FRAND royalties have given rise to intractable disputes regarding the manner in which such royalties should be calculated and adjudicated.

Accordingly, numerous SDOs around the world have adopted RF licensing policies and many widely adopted standards, including Bluetooth, USB, IPv6, HTTP, HTML and XML, are distributed on an RF basis.

Digital shadows enable a more comprehensive understanding and monitoring of processes on shop floor level. Thus, process information becomes available between decision levels, and the aforementioned criteria regarding quality, cost, or safety can be included in control decisions for production processes. The contextual data for digital shadows typically arises from heterogeneous sources. At shop floor level, the proximity to the process requires usage of available data as well as domain knowledge. Data sources need to be selected, synchronized, and processed. Especially high-frequency data requires algorithms for intelligent distribution and efficient filtering of the main information using real-time devices and in-network computing. Real-time data is enriched by simulations, metadata from product planning, and information across the whole process chain. Well-established analytical and empirical models serve as the base for new hybrid, gray box approaches. These models are then applied to optimize production process control by maximizing the productivity under given quality and safety constraints.

The paradigm of Line-less Mobile Assembly Systems (LMAS) provides a solution for the future of assembly by mobilizing all resources. Thus, dynamic product routes through spatiotemporally configured assembly stations on a shop floor free of fixed obstacles are enabled. In this chapter, we present research focal points on different levels of LMAS, starting with the macroscopic level of formation planning, followed by the mesoscopic level of mobile robot control and multipurpose input devices and the microscopic level of services, such as interpreting autonomous decisions and in-network computing. We provide cross-level data and knowledge transfer through a novel ontology-based knowledge management.

Consequently, it requires a technical infrastructure that can support the agile deployment of these concepts and corresponding high-level applications, which, e.g., demand the processing of massive data in motion and at rest. As such, key research aspects are the support for low-latency control loops, concepts on scalable data stream processing, deployable information security, and semantically rich and efficient long-term storage. In particular, such an infrastructure cannot continue to be limited to machines and sensors, but additionally needs to encompass networked environments: production cells, edge computing, and location-independent cloud infrastructures. Finally, in light of the envisioned WWL, i.e., the interconnection of production sites, the technical infrastructure must be advanced to support secure and privacy-preserving industrial collaboration. To evolve today’s production sites and lay the infrastructural foundation for the IoP, we identify five broad streams of research: (1) adapting data and stream processing to heterogeneous data from distributed sources, (2) ensuring data interoperability between systems and production sites, (3) exchanging and sharing data with different stakeholders, (4) network security approaches addressing the risks of increasing interconnectivity, and (5) security architectures to enable secure and privacy-preserving industrial collaboration.

Consequently, to ensure end-to-end secure communication and authentication, (i) traditional industrial protocols, e.g., Modbus, are retrofitted with TLS support, and (ii) modern protocols, e.g., MQTT, are directly designed to use TLS. To understand whether these changes indeed lead to secure Industrial Internet of Things deployments, i.e., using TLS-based protocols, which are configured according to security best practices, we perform an Internet-wide security assessment of ten industrial protocols covering the complete IPv4 address space. Our results show that both, retrofitted existing protocols and newly developed secure alternatives, are barely noticeable in the wild. While we find that new protocols have a higher TLS adoption rate than traditional protocols (7.2 \% vs. 0.4 \%), the overall adoption of TLS is comparably low (6.5 \% of hosts). Thus, most industrial deployments (934,736 hosts) are insecurely connected to the Internet. Furthermore, we identify that 42 \% of hosts with TLS support (26,665 hosts) show security deficits, e.g., missing access control.

Background. As part of our collaborative research of advancing the scope of industrial applications through cybersecurity and privacy, we identified a set of common challenges and pitfalls that surface in such applied interdisciplinary collaborations. Aim. Our goal with this paper is to support researchers in the emerging field of cybersecurity in industrial settings by formalizing our experiences as reference for other research efforts, in industry and academia alike. Method. Based on our experience, we derived a process cycle of performing such interdisciplinary research, from the initial idea to the eventual dissemination and paper writing. This presented methodology strives to successfully bootstrap further research and to encourage further work in this emerging area. Results. Apart from our newly proposed process cycle, we report on our experiences and conduct a case study applying this methodology, raising awareness for challenges in cybersecurity research for industrial applications. We further detail the interplay between our process cycle and the data lifecycle in applied research data management. Finally, we augment our discussion with an industrial as well as an academic view on this research area and highlight that both areas still have to overcome significant challenges to sustainably and securely advance industrial applications.

As companies employ numerous, frequently mutually incompatible data management and preservation approaches, interorganizational data sharing and reuse regularly requires human interaction and is thus associated with high overhead costs.

We propose FactStack, a unified approach to data management and preservation based upon a novel combination of existing Web-standards and tightly integrated with the HTTP protocol itself. Based on the FactDAG model, FactStack guides and supports the full data lifecycle in a FAIR and interoperable manner, independent of individual software solutions and backward-compatible with existing resource oriented architectures. We describe our reference implementation of the approach and evaluate its performance, showcasing scalability even to high-throughput applications.

Our extensive literature review of previous approaches shows that these needs for cross-company information retrieval are widely acknowledged, but related work currently only addresses them insufficiently. To overcome these concerns, we present PrivAccIChain, a secure, privacy-preserving architecture for improving the multi-hop information retrieval with stakeholder accountability along supply chains. To address use case-specific needs, we particularly introduce an adaptable configuration of transparency and data privacy within our design. Hence, we enable the benefits of information sharing as well as multi-hop tracking and tracing even in supply chains that include mutually distrusting stakeholders. We evaluate the performance of PrivAccIChain and demonstrate its real-world feasibility based on the information of a purchasable automobile, the e.GO Life. We further conduct an in-depth security analysis and propose tunable mitigations against common attacks.

However, the typically small number of privacy peers enable single adversaries to mimic distributed services. We thus present AnonBoot, a Sybil-resistant medium to securely bootstrap distributed anonymity services via public blockchains. AnonBoot enforces that peers periodically create a small proof of work to refresh their eligibility for providing secure anonymity services. A pseudo-random, locally replicable bootstrapping process using on-chain entropy then prevents biasing the election of eligible peers.

Complementarily, suppliers need to keep any data irrelevant to such routine checks secret to remain competitive.

The vision of an Internet of Production promises the establishment of a Worldwide Lab, where data from every process in the network can be utilized, even interorganizational and across domains. While numerous existing approaches consider interoperability from an interface and communication system perspective, fundamental questions of data and information interoperability remain insufficiently addressed. In this paper, we identify ten key issues, derived from three distinctive real-world use cases, that hinder large-scale data interoperability for industrial processes. Based on these issues we derive a set of five key requirements for future (IoT) data layers, building upon the FAIR data principles.

Apart from the obvious usage for industry applications in human-robot interaction, acquiring the emotional state of a person automatically also is of great potential for the health domain, especially in psychology and psychiatry. Here, evaluation of human emotion is often done using oral feedback or questionnaires during doctor-patient sessions. However, this can be perceived as intrusive by the patient. Furthermore, the evaluation can only be done in a non-continuous manner, e.g. once a week during therapy sessions. In contrast, using automatic emotion detection, the affect state of a person can be evaluated in a continuous non-intrusive manner, for example to detect early on-sets of depression. An additional benefit of automatic emotion recognition is the objectivity of such an approach, which is not influenced by the perception of the patient and the doctor. To reach the goal of objectivity, it is important, that the source of the emotion is not easily manipulable, e.g. as in the speech modality. To circumvent this caveat, novel approaches in emotion detection research the potential of using physiological measures, such as galvanic skin sensors or pulse meters. In this paper we outline a way of detecting emotion from brain waves, i.e., EEG data. While EEG allows for a continuous, real-time automatic emotion recognition, it furthermore has the charm of measuring the affect close to the point of emergence: the brain. Using EEG data for emotion detection is nevertheless a challenging task: Which features, EEG channel locations and frequency bands are best suited for is an issue of ongoing research. In this paper we evaluate the use of state of the art feature extraction, feature selection and classification algorithms for EEG emotion classification using data from the de facto standard dataset, DEAP. Moreover, we present results that help choose methods to enhance classification performance while simultaneously reducing computational complexity.}, url = {/fileadmin/papers/2016/2016-ackermann-healthcom-emorec.pdf}, web_url2 = {http://ieeehealthcom2016.com/}, misc2 = {Online}, publisher = {IEEE}, booktitle = {2016 IEEE 18th International Conference on e-Health Networking, Applications and Services (Healthcom)}, event_place = {Munich, Germany}, event_name = {2016 IEEE 18th International Conference on e-Health Networking, Applications and Services (Healthcom)}, event_date = {September 14-17, 2016}, language = {en}, ISBN = {978-1-5090-3370-6}, reviewed = {1}, author = {Ackermann, Pascal and Kohlschein, Christian and Bitsch Link, J{\'o} Agila and Wehrle, Klaus and Jeschke, Sabina} } @Article { 2015-cheng-piap-jmu, title = {Psychologist in a Pocket: Lexicon Development and Content Validation of a Mobile-Based App for Depression Screening}, journal = {JMIR Mhealth Uhealth}, year = {2016}, month = {7}, day = {20}, volume = {4}, number = {3}, pages = {e88}, tags = {piap}, web_url = {http://mhealth.jmir.org/2016/3/e88/}, web_url2 = {http://www.ncbi.nlm.nih.gov/pubmed/27439444}, misc2 = {Online}, language = {en}, ISSN = {2291-5222}, DOI = {10.2196/mhealth.5284}, reviewed = {1}, author = {Cheng, Paula Glenda Ferrer and Ramos, Roann Munoz and Bitsch Link, J{\'o} Agila and Jonas, Stephan Michael and Ix, Tim and See, Portia Lynn Quetulio and Wehrle, Klaus} } @Inproceedings { 2016-zimmermann-remp, title = {ReMP TCP: Low Latency Multipath TCP}, year = {2016}, month = {5}, publisher = {IEEE}, booktitle = {Proceedings of the IEEE International Conference on Communications (ICC 2016), Kuala Lumpur, Malaysia}, event_place = {Kuala Lumpur, Malaysia}, event_name = {ICC 2016}, event_date = {23.-27.5.2016}, ISBN = {978-1-4799-6664-6}, ISSN = {1938-1883}, DOI = {10.1109/ICC.2016.7510787}, reviewed = {1}, author = {Fr{\"o}mmgen, Alexander and Erbsh{\"a}user, Tobias and Zimmermann, Torsten and Wehrle, Klaus and Buchmann, Alejandro} } @Inproceedings { 2016-ramos-inpact-lexicon, title = {How Do I Say ''Sad?''

While most of the current techniques are limited to research clinics and require excessive set-up, new consumer EEG devices connected to standard, off-the-shelf mobile devices allow us to lift these limitations. This allows neuropsychological assessment and research in mobile settings, possibly even in remote areas with limited accessibility and infrastructure, thus bringing the equip- ment to the patient, instead of bringing the patient to the equipment. We are developing an Android based mobile framework to perform EEG studies.

In practice, this makes MANETs hard to realize. While 802.11-compliant mobile devices implement the ad-hoc mode on the hardware layer, the software layer typically does not implement support for ad-hoc networking in terms of ad-hoc routing and name resolution protocols. Modern mobile operating systems, such as Android and iOS, even hide the inherent ad-hoc functionality of the wireless card through restrictions in the OS. In contrast to this, support for the 802.11 infrastructure mode is a commodity. We propose establishing ad-hoc networks using the 802.11 infrastructure mode. In MA-Fi (Mobile Ad-Hoc Wi-Fi), a small core of mobile router nodes (RONs) provides infrastruc-ture mode network access to mobile station nodes (STANs). As RONs also act as a station in infrastructure networks of other RONs, MA-Fi achieves multi-hop communication between RON and STAN devices in the overall network. We show the creation and operation of mobile ad-hoc networks using MA-Fi. We focus on mobility of RONs and STANs as well as topology control in the overall network.}, url = {fileadmin/papers/2011/2011-wirtz-wintech.pdf}, misc = {Online}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the Sixth ACM International Workshop on Wireless Network Testbeds, Experimental evaluation and Characterization (WiNTECH 2011), Las Vegas, NV, USA}, event_place = {Las Vegas, Nevada, USA}, event_name = {The Sixth ACM International Workshop on Wireless Network Testbeds, Experimental evaluation and Characterization}, event_date = {2011-09-19}, language = {en}, ISBN = {978-1-4503-0867-0}, DOI = {10.1145/2030718.2030737}, reviewed = {1}, author = {Wirtz, Hanno and Backhaus, Robert and Hummen, Ren{\'e} and Wehrle, Klaus} } @Inproceedings { VaegsABW2011, title = {Efficient Power Management Using Out-of-Band Signaling}, year = {2011}, month = {9}, day = {16}, pages = {77-80}, abstract = {A tremendous amount of energy is wasted today, because computing devices are left running all the time even though they are needed only sporadically. Especially in office environments many devices (e.g., printers) are very rarely turned off, because they need to be available from time to time and because it is inconvenient having to switch them on and off manually. Existing solutions, such as Wake-on-LAN (WoL), provide support for managing the power consumption of the network devices remotely using an always-on data channel. However, these solutions are inefficient, because power to the network interface has to be maintained even when the host system is asleep just to ensure remote accessibility. We propose a Wireless Sensor Network (WSN) based out-of-band signaling architecture for network interfaces which minimizes the systems’ power consumption during the large idle periods when nobody is using them. This is done by separating the data and control channels on the Internet-enabled devices using a low-power out-of-band signaling channel based on battery driven, energy scavenging devices. Unlike existing solutions, which only allow parts of the system to go in sleep modes, our architecture allows the whole system, including the main power supply, to be shut down. Our initial investigation indicates a significant reduction in energy consumption of devices during idle times compared to the existing in-band signaling mechanisms such as WoL.}, keywords = {Energy Saving, Wireless Sensor Network, Out-of-Band Signalling}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2011/2011-vaegs-fgsn-ecocom.pdf}, misc2 = {Online}, booktitle = {Proceedings of the 10th GI/ITG KuVS Fachgespr{\"a}ch Drahtlose Sensornetze (FGSN), Paderborn, Germany}, institution = {RWTH Aachen University}, event_place = {Paderborn, Germany}, event_name = {10th GI/ITG KuVS Fachgespr{\"a}ch Drahtlose Sensornetze (FGSN11)}, event_date = {September 15-16, 2011}, language = {en}, reviewed = {1}, author = {Vaegs, Tobias and Alizai, Muhammad Hamad and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} } @Inproceedings { 2011-ipsn-alizai-pad, title = {Probabilistic Addressing: Stable Addresses in Unstable Wireless Networks}, year = {2011}, month = {4}, url = {fileadmin/papers/2011/2011-ipsn-alizai-pad.pdf}, misc2 = {Online}, publisher = {ACM}, address = {New York, NY, USA}, booktitle = {Proceedings of the 10th ACM/IEEE International Conference on Information Processing in Sensor Networks (IPSN 2011), Chicago, IL, USA}, event_place = {Chicago, IL, USA}, language = {en}, ISBN = {978-1-60558-988-6}, reviewed = {1}, author = {Alizai, Muhammad Hamad and Vaegs, Tobias and Landsiedel, Olaf and G{\"o}tz, Stefan and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} } @Poster { 2011-03-vomLehn-NSDI-PrivacyOnWeb, title = {Work in Progress: Uncovering the Privacy Implications of Web Usage [Poster]}, year = {2011}, month = {3}, note = {poster and abstract}, url = {fileadmin/papers/2011/2011-03-vomLehn-NSDI-PrivacyOnWeb.pdf}, misc2 = {Online}, booktitle = {8th USENIX Symposium on Networked Systems Design and Implementation (NSDI '11), Boston, MA, USA}, organization = {Usenix}, event_place = {Boston, MA, USA}, event_name = {NSDI}, event_date = {March 30 – April 1, 2011}, state = {accepted}, language = {en}, reviewed = {1}, author = {vom Lehn, Hendrik and Bitsch Link, J{\'o} Agila and Wehrle, Klaus} } @Inproceedings { 2010-sensys-alizai-tinywifi, title = {Poster Abstract: TinyOS Meets Wireless Mesh Networks}, year = {2010}, month = {11}, pages = {429-430}, abstract = {We present TinyWifi, a nesC code base extending TinyOS to support Linux powered network nodes.

The header bits take the role of pilot bits having perfect reliability. These bits are distributed over the frame as strong supporting points for the MAP decoder which results in a significant enhancement of the output speech quality compared to the benchmark scheme using ISCD for speech only. For this approach, we exploit new cross-layer concepts that support the direct communication between non-adjacent layers.

Additionally, we show that KleeNet integrates well into TinyOS application development life cycle with minimum manual effort, making it easy for developers to test their applications.}, tags = {kleenet}, url = {fileadmin/papers/2008/2008-09-Sasnauskas-FGSN08-BugHunting.pdf}, web_url = {ftp://ftp.inf.fu-berlin.de/pub/reports/tr-b-08-12.pdf}, misc2 = {Print}, publisher = {Freie Universit{\"a}t Berlin, Institute of Computer Science}, address = {Berlin, Germany}, booktitle = {Proceedings of the 7th GI/ITG Fachgespraech Wireless Sensor Networks, Berlin, Germany}, institution = {Chair of Communication and Distributed Systems (ComSys)}, language = {en}, reviewed = {1}, author = {Sasnauskas, Raimondas and Bitsch Link, J{\'o} Agila and Alizai, Muhammad Hamad and Wehrle, Klaus} } @Inproceedings { 200808OsechasEMBC08RatPack, title = {Ratpack: Wearable Sensor Networks for Animal Observation}, year = {2008}, month = {8}, day = {20}, pages = {538--541}, abstract = {The goal of our project is to describe the behavior of rats.

Unstable links, although often promising to be of large routing progress, are not considered for packet forwarding as link estimators typically cannot handle their dynamics. In this paper we introduce short-term link estimation to capture link dynamics at a high resolution in time and to identify when these render a link temporarily reliable or unreliable. We identify such dynamics based on packet overhearing, predict short-term availability and unavailability, and adapt neighbor tables, thereby enlarging the set of links useable by any routing algorithm.
