In such environments, attackers can derive sensitive private information of IoT device owners, e.g., daily routines or secret supply chain procedures, when sniffing on IoT communication and linking IoT devices and owner. Furthermore, untrusted networks do not provide IoT devices with any protection against attacks from the Internet. Anonymous communication using onion routing provides a well-proven mechanism to keep the relationship between communication partners secret and (optionally) protect against network attacks. However, the application of onion routing is challenged by protocol incompatibilities and demanding cryptographic processing on constrained IoT devices, rendering its use infeasible. To close this gap, we tailor onion routing to the IoT by bridging protocol incompatibilities and offloading expensive cryptographic processing to a router or web server of the IoT device owner. Thus, we realize resource-conserving access control and end-to-end security for IoT devices. To prove applicability, we deploy onion routing for the IoT within the well-established Tor network enabling IoT devices to leverage its resources to achieve the same grade of anonymity as readily available to traditional devices.}, tags = {internet-of-production}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-hiller-tailoring.pdf}, publisher = {IEEE}, booktitle = {Proceedings of the 27th IEEE International Conference on Network Protocols (ICNP '19), October 7-10, 2019, Chicago, IL, USA}, event_place = {Chicago, IL, USA}, event_name = {27th IEEE International Conference on Network Protocols (ICNP 2019)}, event_date = {7-10.

However, using the SMGW as proxy, local devices can neither review the security of these remote connections established by the SMGW nor enforce higher security guarantees than established by the all in one configuration of the SMGW which does not allow for use case-specific security settings.

The prevalence of online media and the opportunity for users to express opinions in comments magnifies the problem. Governments, organizations, and companies can exploit this situation for biasing opinions. Typically, they deploy a large number of pseudonyms to create an impression of a crowd that supports specific opinions. Side channel information (such as IP addresses or identities of browsers) often allows a reliable detection of pseudonyms managed by a single person. However, while spoofing and anonymizing data that links these accounts is simple, a linking without is very challenging. In this paper, we evaluate whether stylometric features allow a detection of such doppelg{\"a}ngers within comment sections on news articles. To this end, we adapt a state-of-the-art doppelg{\"a}ngers detector to work on small texts (such as comments) and apply it on three popular news sites in two languages. Our results reveal that detecting potential doppelg{\"a}ngers based on linguistics is a promising approach even when no reliable side channel information is available.

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.}, keywords = {Internet of Production; Cyber-Physical Systems; Data Processing; Low Latency; Secure Industrial Collaboration}, tags = {internet-of-production}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-pennekamp-iop-infrastructure.pdf}, publisher = {IEEE}, booktitle = {Proceedings of the 2nd IEEE International Conference on Industrial Cyber-Physical Systems (ICPS '19), May 6-9, 2019, Taipei, TW}, event_place = {Taipei, TW}, event_date = {May 6-9, 2019}, ISBN = {978-1-5386-8500-6/19}, DOI = {10.1109/ICPHYS.2019.8780276}, reviewed = {1}, author = {Pennekamp, Jan and Glebke, Ren{\'e} and Henze, Martin and Meisen, Tobias and Quix, Christoph and Hai, Rihan and Gleim, Lars and Niemietz, Philipp and Rudack, Maximilian and Knape, Simon and Epple, Alexander and Trauth, Daniel and Vroomen, Uwe and Bergs, Thomas and Brecher, Christian and B{\"u}hrig-Polaczek, Andreas and Jarke, Matthias and Wehrle, Klaus} } @Techreport { 2019-rueth-blitzstart, title = {Blitz-starting QUIC Connections}, year = {2019}, month = {5}, day = {8}, number2 = {arXiv:1905.03144 [cs.NI]}, pages = {1--8}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-rueth-blitzstart.pdf}, web_url = {https://arxiv.org/abs/1905.03144}, misc2 = {Online}, publisher = {COMSYS, RWTH Aachen University}, address = {Ahornstr. 55, 52074 Aachen, Germany}, institution = {COMSYS, RWTH Aachen University}, type = {Technical Report}, language = {en}, author = {R{\"u}th, Jan and Wolsing, Konrad and Serror, Martin and Wehrle, Klaus and Hohlfeld, Oliver} } @Inproceedings { 2019_wagner_dispute_resolution, title = {Dispute Resolution for Smart Contract-based Two Party Protocols}, year = {2019}, month = {5}, abstract = {Blockchain systems promise to mediate interactions of mutually distrusting parties without a trusted third party. However, protocols with full smart contract-based security are either limited in functionality or complex, with high costs for secured interactions. This observation leads to the development of protocol-specific schemes to avoid costly dispute resolution in case all participants remain honest. In this paper, we introduce SmartJudge, an extensible generalization of this trend for smart contract-based two-party protocols. SmartJudge 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. This way, SmartJudge avoids verification costs in absence of disputes and sustains interaction confidentiality among honest parties. We implement verifier smart contracts for cross-blockchain trades and exchanging digital goods and show that SmartJudge can reduce costs by 46-50\% and 22\% over current state of the art, respectively.}, keywords = {Ethereum,Bitcoin,smart contracts,two-party protocols,dispute resolution,cross-blockchain trades}, tags = {mynedata, impact-digital, rfc}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-wagner-dispute.pdf}, publisher = {IEEE}, booktitle = {IEEE International Conference on Blockchain and Cryptocurrency 2019 (ICBC 2019)}, event_place = {Seoul, South Korea}, event_name = {IEEE International Conference on Blockchain and Cryptocurrency 2019}, language = {English}, DOI = {10.1109/BLOC.2019.8751312}, reviewed = {1}, author = {Wagner, Eric and V{\"o}lker, Achim and Fuhrmann, Frederik and Matzutt, Roman and Wehrle, Klaus} } @Techreport { 2019-hohlfeld-santa-tr, title = {Application-Agnostic Offloading of Packet Processing}, year = {2019}, month = {4}, day = {1}, number2 = {arXiv:1904.00671 [cs.NI]}, pages = {1--14}, tags = {maki}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-hohlfeld-santatr.pdf}, web_url = {https://arxiv.org/abs/1904.00671}, misc2 = {Online}, publisher = {COMSYS, RWTH Aachen University}, address = {Ahornstr. 55, 52074 Aachen, Germany}, institution = {COMSYS, RWTH Aachen University}, type = {Technical Report}, language = {en}, author = {Hohlfeld, Oliver and Reelfs, Helge and R{\"u}th, Jan and Schmidt, Florian and Zimmermann, Torsten and Hiller, Jens and Wehrle, Klaus} } @Article { 2019_henze_flexible_netzwerkstrukturen_iop, title = {Flexible Netzwerkarchitekturen f{\"u}r das Internet of Production}, journal = {ITG-news}, year = {2019}, month = {4}, volume = {02/2019}, pages = {7-8}, tags = {internet-of-production,reflexes}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2019/2019-henze-itg-iop-networkarchitectures.pdf}, publisher = {Informationstechnische Gesellschaft im VDE}, address = {Frankfurt am Main}, author = {Henze, Martin and Glebke, Ren{\'e} and Wehrle, Klaus} } @Inproceedings { 2019-rueth-icmp, title = {Hidden Treasures -
