Thus, deploying redundant hardware for both local and wide area communication, along with protocols that leverage these redundancies for automatic and timely failovers, is fundamental. This paper presents a comprehensive overview of key protocols (PRP/HSR, MPLS-TP, and MPTCP) which offer robust recovery mechanisms. Additionally, it provides a specific concept and topology that effectively combine the presented protocols to ensure resilient communication from the control center to substation devices. ven2us Proceedings of the CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems, November 7-8, 2024, Chicago, USA Chicago CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems November 7-8, 2024 accepted 1 Ina BereniceFink MarkusDahlmanns GerritErichsen KlausWehrle inproceedings 2024-dahlmanns-cired 2024 6 19 The increasing demands on the power grid require intelligent and flexible solutions that ensure the grid's stability. Many of these measures involve sophisticated communication between the control center and the stations that is not efficiently realizable using traditional protocols, e.g., IEC 60870-5-104. 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. Additionally, in accordance with IEC 61850, we envision the control center to communicate with the station devices using MMS by using the station RTU as a proxy. ven2us Proceedings of the CIRED workshop on Increasing Distribution Network Hosting Capacity 2024, June 19-20, 2024, Vienna, Austria Vienna CIRED workshop on Increasing Distribution Network Hosting Capacity 2024 June 19-20, 2024 10.1049/icp.2024.2096 1 MarkusDahlmanns Ina BereniceFink GerritErichsen GuosongLin ThomasHammer BurkhardBorkenhagen SebastianSchneider ChristofMaahsen KlausWehrle inproceedings 2023-lorz-cired 2023 3286-3290 ven2us 27th International Conference on Electricity Distribution (CIRED 2023), Rome, Italy, June 12-15, 2023 Rome, Italy International Conference & Exhibition on Electricity Distribution (CIRED) June 12-15, 2023 10.1049/icp.2023.0864 1 TobiasLorz JohannJaeger AntigonaSelimaj ImmanuelHacker AndreasUlbig Jan-PeterHeckel ChristianBecker MarkusDahlmanns Ina BereniceFink KlausWehrle GerritErichsen MichaelSchindler RainerLuxenburger GuosongLin inproceedings 2020_delacadena_trafficsliver 2020 11 12 1971-1985 Website fingerprinting (WFP) aims to infer information about the content of encrypted and anonymized connections by observing patterns of data flows based on the size and direction of packets. By collecting traffic traces at a malicious Tor entry node — one of the weakest adversaries in the attacker model of Tor — a passive eavesdropper can leverage the captured meta-data to reveal the websites visited by a Tor user. As recently shown, WFP is significantly more effective and realistic than assumed. Concurrently, former WFP defenses are either infeasible for deployment in real-world settings or defend against specific WFP attacks only. To limit the exposure of Tor users to WFP, we propose novel lightweight WFP defenses, TrafficSliver, which successfully counter today’s WFP classifiers with reasonable bandwidth and latency overheads and, thus, make them attractive candidates for adoption in Tor. Through user-controlled splitting of traffic over multiple Tor entry nodes, TrafficSliver limits the data a single entry node can observe and distorts repeatable traffic patterns exploited by WFP attacks. We first propose a network-layer defense, in which we apply the concept of multipathing entirely within the Tor network. We show that our network-layer defense reduces the accuracy from more than 98% to less than 16% for all state-of-the-art WFP attacks without adding any artificial delays or dummy traffic. We further suggest an elegant client-side application-layer defense, which is independent of the underlying anonymization network. By sending single HTTP requests for different web objects over distinct Tor entry nodes, our application-layer defense reduces the detection rate of WFP classifiers by almost 50 percentage points. Although it offers lower protection than our network-layer defense, it provides a security boost at the cost of a very low implementation overhead and is fully compatible with today’s Tor network.

While hundreds of isolated solutions exist to utilize this data, e.g., optimizing processes or monitoring machine conditions, the lack of a unified data handling and exchange mechanism hinders the implementation of approaches to improve the quality of decisions and processes in such an interconnected environment. 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. We propose to address them by creating FactDAG, a conceptual data layer model for maintaining a provenance-based, directed acyclic graph of facts, inspired by successful distributed version-control and collaboration systems. Eventually, such a standardization should greatly shape the future of interoperability in an interconnected production industry.

Recent studies have shown that WFP targeting Tor users is notably more effective than previously expected. Concurrently, state-of-the-art defenses have been proven to be less effective. In response, we present a novel WFP defense that splits traffic over multiple entry nodes to limit the data a single malicious entry can use. Here, we explore several traffic-splitting strategies to distribute user traffic. We establish that our weighted random strategy dramatically reduces the accuracy from nearly 95% to less than 35% for four state-of-the-art WFP attacks without adding any artificial delays or dummy traffic. https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-delacadena-splitting-defense.pdf ACM Proceedings of the 26th ACM SIGSAC Conference on Computer and Communications Security (CCS '19), November 11-15, 2019, London, United Kingdom London, United Kingdom November 11-15, 2019 978-1-4503-6747-9/19/11 10.1145/3319535.3363249 1 WladimirDe la Cadena AsyaMitseva JanPennekamp JensHiller FabianLanze ThomasEngel KlausWehrle AndriyPanchenko inproceedings 2019_pennekamp_multipath 2019 10 7 Users of an onion routing network, such as Tor, depend on its anonymity properties. However, especially malicious entry nodes, which know the client’s identity, can also observe the whole communication on their link to the client and, thus, conduct several de-anonymization attacks. To limit this exposure and to impede corresponding attacks, we propose to multipath traffic between the client and the middle node to reduce the information an attacker can obtain at a single vantage point. To facilitate the deployment, only clients and selected middle nodes need to implement our approach, which works transparently for the remaining legacy nodes. Furthermore, we let clients control the splitting strategy to prevent any external manipulation.

These data plane programs are, however, limited in per-packet time budget (e.g., 67.2 ns at 10GbE) and program size, making program optimization imperative. Existing approaches focus on optimizing the distribution of flow rules in fixed data planes or they are limited to a single switch. We see great potential in integrating the network topology into program optimization. maki https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-krude-chain-opt.pdf ACM NetPL '19: ACM SIGCOMM Workshop on Networking and Programming Languages Beijing, China 978-1-4503-6877-3/19/08 10.1145/3341561.3349590 1 JohannesKrude MatthiasEichholz MaximilianWinck KlausWehrle MiraMezini inproceedings 2019_pennekamp_infrastructure 2019 5 8 31-37 New levels of cross-domain collaboration between manufacturing companies throughout the supply chain are anticipated to bring benefits to both suppliers and consumers of products. Enabling a fine-grained sharing and analysis of data among different stakeholders in an automated manner, such a vision of an Internet of Production (IoP) introduces demanding challenges to the communication, storage, and computation infrastructure in production environments. In this work, we present three example cases that would benefit from an IoP (a fine blanking line, a high pressure die casting process, and a connected job shop) and derive requirements that cannot be met by today’s infrastructure. In particular, we identify three orthogonal research objectives: (i) real-time control of tightly integrated production processes to offer seamless low-latency analysis and execution, (ii) storing and processing heterogeneous production data to support scalable data stream processing and storage, and (iii) secure privacy-aware collaboration in production to provide a basis for secure industrial collaboration. Based on a discussion of state-of-the-art approaches for these three objectives, we create a blueprint for an infrastructure acting as an enabler for an IoP.

This attack can be performed by a local passive eavesdropper – one of the weakest adversaries in the attacker model of anonymization networks such as Tor. In this paper, we present a novel website fingerprinting attack. Based on a simple and comprehensible idea, our approach outperforms all state-of-the-art methods in terms of classification accuracy while being computationally dramatically more efficient. In order to evaluate the severity of the website fingerprinting attack in reality, we collected the most representative dataset that has ever been built, where we avoid simplified assumptions made in the related work regarding selection and type of webpages and the size of the universe. Using this data, we explore the practical limits of website fingerprinting at Internet scale. Although our novel approach is by orders of magnitude computationally more efficient and superior in terms of detection accuracy, for the first time we show that no existing method – including our own – scales when applied in realistic settings. With our analysis, we explore neglected aspects of the attack and investigate the realistic probability of success for different strategies a real-world adversary may follow. https://www.comsys.rwth-aachen.de/fileadmin/papers/2016/2016-panchenko-ndss-fingerprinting.pdf https://www.informatik.tu-cottbus.de/~andriy/zwiebelfreunde/ Internet Society Proceedings of the 23rd Annual Network and Distributed System Security Symposium (NDSS '16), February 21-24, 2016, San Diego, CA, USA San Diego, CA, USA February 21-24, 2016 978-1-891562-41-9 10.14722/ndss.2016.23477 1 AndriyPanchenko FabianLanze AndreasZinnen MartinHenze JanPennekamp KlausWehrle ThomasEngel inproceedings 2015-zimmermann-remp 2015 12 1 ACM Proceedings of the 2015 CoNEXT on Student Workshop, CoNEXT Student Workshop, Heidelberg, Germany Heidelberg, Germany CoNEXT 2015 1.-4.12.2015 1 AlexanderFrömmgen TobiasErbshäuser TorstenZimmermann KlausWehrle AlejandroBuchmann incollection 2013-wtc-eggert-sensorcloud 2014 12 14 203-218 sensorcloud fileadmin/papers/2013/2013-wtc-eggert-sensorcloud.pdf Online Krcmar, Helmut and Reussner, Ralf and Rumpe, Bernhard Springer Trusted Cloud Computing en 978-3-319-12717-0 10.1007/978-3-319-12718-7_13 1 MichaelEggert RogerHäußling MartinHenze LarsHermerschmidt RenéHummen DanielKerpen AntonioNavarro Pérez BernhardRumpe DirkThißen KlausWehrle inproceedings Punal12_PowerLoading 2012 1-4 Proc. of the IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM'12) OscarPuñal HumbertoEscudero JamesGross inproceedings Punal11 2011 124--132 Proc. of the 73rd IEEE Vehicular Technology Conference (VTC-Spring'11) OscarPuñal HumbertoEscudero JamesGross inproceedings Eisenblaetter10 2010 227 -236 Proc. of the 8th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks (WiOpt'10) AndreasEisenblätter Hans-FlorianGeerdes JamesGross OscarPuñal JonasSchweiger article Gross09a Elsevier Performance Evaluation Journal 2009 66 3-5 240--257 JamesGross MarcEmmelmann OscarPuñal AdamWolisz inproceedings Gross09 2009 220--233 Proc. of the 8th International IFIP Networking Conference (NETWORKING'09) JamesGross OscarPuñal MarcEmmelmann inproceedings 2009-thissen-GI-IMS 2009 2561-2573 Print S.
