Secret values can be stored in databases after encrypting them (in particular by applying a secret sharing schema) but, in practice, these confidential values often need to be processed otherwise losing their usefulness. A possible solution is secure multiparty computation (known as MPC) that allows the computation of various functions directly on encrypted data, thus guaranteeing the confidentiality of the information during the whole process of querying databases. The main drawback for such systems is performance degradation, as secure computations on secret data imply multiple communication rounds and the exchange of messages with different lengths. In this paper, two sets of MPC subprotocols are benchmarked and compared considering the number of rounds and the communication cost, in order to assess which one of these parameters has a bigger impact on performance. Our results show that a small cost is more important in terms of efficiency than reducing the number of rounds.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127343697","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 fact that such devices are handling sensitive data makes them a target for attackers. Many attack prevention mechanisms are deployed with a last line of defense that focuses on the containment principle. Currently, iOS treats each 3rd party application alike which may lead to security flaws. We propose a framework in which each application has a custom sandboxed environment. We investigated the current confinement architecture used by Apple and built a solution on top of it.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114402232","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}

This has led to the need for efficient dimensionality reduction techniques, mathematical procedures that transform the high-dimensional data into a meaningful, reduced representation. Principal Component Analysis (PCA) is a well-known dimensionality reduction technique used in the field of hyperspectral satellite images. However, PCA suffers from high computational costs and increased complexity, an issue that led to elaborating PCA adaptations capable of running on multi-core computing architectures. This paper proposes a parallel implementation of the geometrical PCA approximation (gaPCA) algorithm. Three parallel implementations are studied: two on multi-core CPUs and a NVIDIA Graphics Processing Units (GPU) CUDA accelerated implementation. Our results show significant speedups of the parallel implementations when applied on hyperspectral image datasets. Our results show that on the Intel Core i5 CPU, Python multi-core implementation is up to 2.01$times$ faster than its Matlab equivalent. Our GPU PyCUDA implementation is considerably faster than both our Python multi-core CPU implementations: up to 1.76$times$ faster than Intel Core i5-6200U and up to 5.72$times$ faster than the NVIDIA Jetson Nano quad-core ARM A53 CPU. We performed data analysis on the output data for the three methods and the maxim relative error was less than 0.001%.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128358564","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}

Industry 4.0, the current wave of the industrial revolution– dubbed the data revolution -, integrates these advances in communication and computational systems with the Internet, resulting in a paradigm shift towards the (Industrial) Internet of Things. Automation systems and remote data acquisition systems evolved over the last years from classic solutions based on wired infrastructure to modern, flexible solutions bringing together wireless communications, battery powered devices and wireless sensors networks. In this paper we first define the main problems encountered in modern wireless automation systems - small distance limitations of wireless communication solutions, weak security or complete lack of security in data transmission, and high energy consumption of battery powered remote data acquisition systems. In order to address these limitations, we propose, implement, trial-run and benchmark a novel low power LoRa-based flexible hardware architecture for use in industrial remote monitoring and control. We obtain a LoS capability above 3km and a calculated autonomy of about 10 years, exceeding the capabilities of current State of the Art solutions.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133432669","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 purpose of this paper is the implementation of a radio direction-finding system which uses 2 separate receivers instead of an antenna array, as most systems use today. In order to make both receivers use the same clock signal a synchronization mechanism was introduced. However, oscillator from the radio analog front end induces a phase shift into the system which differs in time. The results show that this effect causes each new packet to be received with a different phase shift, making it impossible to perform an accurate angle estimation from packet to packet, as phase information is necessary to all angle estimation techniques we used.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128644059","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}

This paper presents the architecture and the prototype of an intelligent platform for drug administration with the following key functionalities: adding specific medications to user’s profile, searching for potential contraindications or side effects, and defining alerts of drug administration in the provided calendar, based on the physician’s prescription. The platform aggregates leaflets from two sources (Biofarm and HelpNet) using Natural Language Processing (NLP) techniques tailored for Romanian language and provides full-text search via Elasticsearch.

The idea is to implement an overlay network between vehicles and the cloud, based on distributed Docker containers, orchestrated by Open Baton. This solution uses TOSCA YAML as data model and descriptor language. The performance of the container-to- container connectivity was evaluated with iPerf.

Year after year, performance improves, to the point that it is becoming difficult to differentiate between the strengths of deep neural network models given our current data sets. However, due to their significant requirements in terms of hardware resources, all but few architectures are dependent on cloud environments. Yet, there are many use cases for neural networks in a variety of areas, many of which require consumer-grade hardware or highly resource constrained embedded devices. This paper offers a comparison of selected state-of-the-art neural network miniaturization methods, and proposes a new approach, PXNOR, that achieves a noteworthy accuracy, remarkable inference speed and significant memory savings. PXNOR seeks to fully replace traditional convolutional filters with approximate operations, while replacing all multiplications and additions with simpler, much faster versions such as XNOR and bitcounting, which are implemented at hardware level on all existing platforms.","PeriodicalId":309683,"journal":{"name":"2019 18th RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132320284","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}
