At the same time, mobile apps have access to various private information, ranging from users' contact lists to their precise locations. As a result, app deployment models and data flows have become too complex and entangled for users to understand. We present CloudAnalyzer, a transparency technology that reveals the cloud usage of smartphone apps and hence provides users with the means to reclaim informational self-determination. We apply CloudAnalyzer to study the cloud exposure of 29 volunteers over the course of 19 days. In addition, we analyze the cloud usage of the 5000 most accessed mobile websites as well as 500 popular apps from five different countries. Our results reveal an excessive exposure to cloud services: 90 \% of apps use cloud services and 36 \% of apps used by volunteers solely communicate with cloud services. Given the information provided by CloudAnalyzer, users can critically review the cloud usage of their apps.}, keywords = {Privacy; Smartphones; Cloud Computing; Traffic Analysis}, tags = {trinics}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-henze-mobiquitous-cloudanalyzer.pdf}, misc2 = {Online}, publisher = {ACM}, booktitle = {Proceedings of the 14th EAI International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services (MobiQuitous '17), November 7-10, 2017, Melbourne, VIC, Australia}, event_place = {Melbourne, VIC, Australia}, event_date = {November 7-10, 2017}, language = {en}, ISBN = {978-1-4503-5368-7}, DOI = {10.1145/3144457.3144471}, reviewed = {1}, author = {Henze, Martin and Pennekamp, Jan and Hellmanns, David and M{\"u}hmer, Erik and Ziegeldorf, Jan Henrik and Drichel, Arthur and Wehrle, Klaus} } @Inproceedings { 2017-panchenko-wpes-fingerprinting, title = {Analysis of Fingerprinting Techniques for Tor Hidden Services}, year = {2017}, month = {10}, day = {30}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-panchenko-wpes-fingerprinting.pdf}, misc2 = {Online}, publisher = {ACM}, booktitle = {Proceedings of the 16th Workshop on Privacy in the Electronic Society (WPES), co-located with the 24th ACM Conference on Computer and Communications Security (CCS), Dallas, TX, USA}, language = {en}, ISBN = {978-1-4503-5175-1}, DOI = {10.1145/3139550.3139564}, reviewed = {1}, author = {Panchenko, Andriy and Mitseva, Asya and Henze, Martin and Lanze, Fabian and Wehrle, Klaus and Engel, Thomas} } @Inproceedings { 2017-henze-trustcom-dcam, title = {Distributed Configuration, Authorization and Management in the Cloud-based Internet of Things}, year = {2017}, month = {8}, day = {1}, pages = {185-192}, tags = {sscilops, ipacs}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-henze-trustcom-dcam.pdf}, misc2 = {Online}, publisher = {IEEE}, booktitle = {Proceedings of the 16th IEEE International Conference on Trust, Security and Privacy in Computing and Communications (IEEE TrustCom), Sydney, NSW, Australia}, language = {en}, ISBN = {978-1-5090-4905-9}, ISSN = {2324-9013}, DOI = {10.1109/Trustcom/BigDataSE/ICESS.2017.236}, reviewed = {1}, author = {Henze, Martin and Wolters, Benedikt and Matzutt, Roman and Zimmermann, Torsten and Wehrle, Klaus} } @Inproceedings { 2017-maurer-trustcom-coinjoin, title = {Anonymous CoinJoin Transactions with Arbitrary Values}, year = {2017}, month = {8}, day = {1}, pages = {522-529}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-maurer-trustcom-coinjoin.pdf}, misc2 = {Online}, publisher = {IEEE}, booktitle = {2017 IEEE Trustcom/BigDataSE/ICESS}, event_place = {Sydney, NSW, Australia}, event_name = {16th IEEE International Conference on Trust, Security and Privacy in Computing and Communications (IEEE TrustCom)}, event_date = {1. - 4.

Unfortunately, this dawning genome era does not only promise tremendous advances in biomedical research but also causes unprecedented privacy risks for the many. Handling storage and processing of large genome datasets through cloud services greatly aggravates these concerns. Current research efforts thus investigate the use of strong cryptographic methods and protocols to implement privacy-preserving genomic computations. We propose FHE-Bloom and PHE-Bloom, two efficient approaches for genetic disease testing using homomorphically encrypted Bloom filters. Both approaches allow the data owner to securely outsource storage and computation to an untrusted cloud. FHE-Bloom is fully secure in the semi-honest model while PHE-Bloom slightly relaxes security guarantees in a trade-off for highly improved performance. We implement and evaluate both approaches on a large dataset of up to 50 patient genomes each with up to 1000000 variations (single nucleotide polymorphisms). For both implementations, overheads scale linearly in the number of patients and variations, while PHE-Bloom is faster by at least three orders of magnitude. For example, testing disease susceptibility of 50 patients with 100000 variations requires only a total of 308.31 s (\(\sigma\)=8.73 s) with our first approach and a mere 0.07 s (\(\sigma\)=0.00 s) with the second. We additionally discuss security guarantees of both approaches and their limitations as well as possible extensions towards more complex query types, e.g., fuzzy or range queries. Both approaches handle practical problem sizes efficiently and are easily parallelized to scale with the elastic resources available in the cloud. The fully homomorphic scheme, FHE-Bloom, realizes a comprehensive outsourcing to the cloud, while the partially homomorphic scheme, PHE-Bloom, trades a slight relaxation of security guarantees against performance improvements by at least three orders of magnitude.}, note = {Proceedings of the 5th iDASH Privacy and Security Workshop 2016}, keywords = {Secure outsourcing; Homomorphic encryption; Bloom filters}, tags = {sscilops; mynedata; rfc}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-ziegeldorf-bmcmedgenomics-bloom.pdf}, misc2 = {Online}, publisher = {BioMed Central}, event_place = {Chicago, IL, USA}, event_date = {November 11, 2016}, language = {en}, ISSN = {1755-8794}, DOI = {10.1186/s12920-017-0277-y}, reviewed = {1}, author = {Ziegeldorf, Jan Henrik and Pennekamp, Jan and Hellmanns, David and Schwinger, Felix and Kunze, Ike and Henze, Martin and Hiller, Jens and Matzutt, Roman and Wehrle, Klaus} } @Article { dombrowski-vdi, title = {Funktechnologien f{\"u}r Industrie 4.0}, journal = {VDE Positionspapier}, year = {2017}, month = {6}, day = {1}, publisher = {VDE - Verband der Elektrotechnik, Elektronik, Informationstechnik e.V.}, address = {Stresemannallee 15, 60596 Frankfurt am Main, Germany}, author = {Aktas, Ismet and Bentkus, Alexander and Bonanati, Florian and Dekorsy, Armin and Dombrowski, Christian and Doubrava, Michael and Golestani, Ali and Hofmann, Frank and Heidrich, Mike and Hiensch, Stefan and Kays, R{\"u}diger and Meyer, Michael and M{\"u}ller, Andreas and ten Brink, Stephan and Petreska, Neda and Popovic, Milan and Rauchhaupt, Lutz and Saad, Ahmad and Schotten, Hans and W{\"o}ste, Christoph and Wolff, Ingo} } @Inproceedings { 2017-henze-ic2e-prada, title = {Practical Data Compliance for Cloud Storage}, year = {2017}, month = {4}, day = {4}, pages = {252-258}, tags = {ssiclops, ipacs}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-henze-ic2e-prada.pdf}, misc2 = {Online}, publisher = {IEEE}, booktitle = {Proceedings of the 2017 IEEE International Conference on Cloud Engineering (IC2E 2017), Vancouver, BC, Canada}, language = {en}, ISBN = {978-1-5090-5817-4}, DOI = {10.1109/IC2E.2017.32}, reviewed = {1}, author = {Henze, Martin and Matzutt, Roman and Hiller, Jens and M{\"u}hmer, Erik and Ziegeldorf, Jan Henrik and van der Giet, Johannes and Wehrle, Klaus} } @Inproceedings { 2017-ziegeldorf-codaspy-priward, title = {Privacy-Preserving HMM Forward Computation}, year = {2017}, month = {3}, day = {22}, pages = {83-94}, tags = {mynedata}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-ziegeldorf-codaspy-priward.pdf}, misc2 = {Online}, publisher = {ACM}, booktitle = {Proceedings of the 7th ACM Conference on Data and Application Security and Privacy (CODASPY 2017), Scottsdale, AZ, USA}, language = {en}, ISBN = {978-1-4503-4523-1}, DOI = {10.1145/3029806.3029816}, reviewed = {1}, author = {Ziegeldorf, Jan Henrik and Metzke, Jan and R{\"u}th, Jan and Henze, Martin and Wehrle, Klaus} } @Inproceedings { 2017-matzutt-mynedata, title = {myneData: Towards a Trusted and User-controlled Ecosystem for Sharing Personal Data}, year = {2017}, pages = {1073-1084}, abstract = {Personal user data is collected and processed at large scale by a handful of big providers of Internet services. This is detrimental to users, who often do not understand the privacy implications of this data collection, as well as to small parties interested in gaining insights from this data pool, e.g., research groups or small and middle-sized enterprises. To remedy this situation, we propose a transparent and user-controlled data market in which users can directly and consensually share their personal data with interested parties for monetary compensation. We define a simple model for such an ecosystem and identify pressing challenges arising within this model with respect to the user and data processor demands, legal obligations, and technological limits. We propose myneData as a conceptual architecture for a trusted online platform to overcome these challenges.
