The experiment was designed to confirm if this is a viable approach to mimicking a heterogeneous group of blackbox devices. In the experiment we focused on only one of the protocols used in the IoT world, the Hypertext Transfer Protocol (HTTP), primarily due to widespread use and mature tooling. Our findings show that it is trivial to learn enough responses to induce deeper probing, and that some of the knowledge discovered in this way could not have been obtained by using any other publicly available resources.","PeriodicalId":442802,"journal":{"name":"2020 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124379672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Novel scenarios are extending the seemingly endless list of use cases for this emerging technology. To avoid ungoverned proliferation and abandoned aerial objects, not only regulations but also technical solutions are indispensable. Authentication of a UAV is required to link to the operator and respective competences. Besides appropriate competences, regulations are depending on regional authorities, which demands a studious concept to avoid insular solutions. This paper proposes a thought-through infrastructure for a secured and global operative authentication system. First, upcoming regulations are considered for the concept to make the system regulatory compliant. Then, to avoid a patchwork of proclaimed solutions, the system design is based on the principle of delegated authority, which allows the respective authorities to keep control over their domains. Further, to associate UAVs with their operators, a cryptographic link is created during a provisioning process. This link is represented by a certificate, comparable with a conventional driver’s license. The system design allows divestment of respective flight permissions, enabled by certificate revocation. Lastly, we constructed a proof-of-concept for the proposed infrastructure solution and compared it to a decentralized approach.","PeriodicalId":442802,"journal":{"name":"2020 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130791088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The device parasitics modelled as a series RLC structure are absorbed in the input and output matching networks by proper design of matching networks in band-pass form using two different synthesis methodologies. The S21 of the amplifier shows 11.2 dB of maximum small signal gain with 2.4 dB ripple along a 700 MHz bandwidth at 2.1 GHz and S11 better than −7dB for 1. 64-2.34GHz. The band-pass matching networks are entirely designed by transmission lines modeling the behavior of the resonant parallel shunt and series LC structures that characterize a band-pass circuit.

Ultra-Wide-Band pulse radar applications demand high performance digitalization of the received RF signal with few GHz of bandwidth. Since high sampling rate analog to digital converters are very expensive and complex, we designed an inexpensive sampling mixer based on the equivalent sample time technique. A sampling mixer uses a bridge with two diodes for capturing a portion of a signal in each period. After a certain amount of repetitive periods, the sampling mixer reconstructs the original RF signal. The reconstructed signal is stretched from the sub-nanoseconds order into the microsecond order. Such stretched RF signal can be digitalized using a low rate analog to digital converter with sampling rate of a few MSa/s.","PeriodicalId":442802,"journal":{"name":"2020 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122137432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially in rooms with a highly symmetric arrangement of the luminaires, fingerprinting suffers from high ambiguity of the received signals. We demonstrate an approach to overcome this ambiguity by expanding fingerprinting by track analysis in 3D VLP based on angle diverse receivers. Furthermore, we give a more detailed insight on the impact of the number and the kind of the segmentations of the related optical elements for the receivers and their effect on the performance of the designed algorithm. We demonstrate that by such an approach the success rate for correct 3D position estimation can be enhanced between 29 % and 64 % in dependence of the respective angular segmentation of the receiver.","PeriodicalId":442802,"journal":{"name":"2020 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124537507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designing these devices as passive (batteryless) in terms of power supply is faced with challenges concerning miniaturization and compliance to standards. To evaluate performance, we introduce a simulation framework that can predict a design’s minimum operating magnetic field strength (Hmin) with an accuracy under 0.1 A/m. The framework combines S-parameter models of the device’s antenna and the ISO-standardized setup (the ISO test PCD assembly) with a data-based nonlinear model of the device’s IC. Techniques for optimizing the energy transfer are discussed (tuning and power matching) and backed by analytical and practical examples. We also demonstrate how to use the simulation framework to determine the impact of the device’s structure on energy transfer. Two designs of small payment accessories are ultimately compared, both as models in the framework and as fabricated samples. By applying power matching instead of tuning, the second design’s size can be reduced by approximately half, without significant change in Hmin. As the predicted Hmin values match the measurements, the results show that multiple design parameters can be varied within the framework to determine their effect on Hmin, which is of great assistance for finding the optimal design.","PeriodicalId":442802,"journal":{"name":"2020 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
