    Programa Oficial de Doutoramento en Tecnoloxías da Información e Comunicacións en Redes Móbiles . 5029P01[Abstract] Reliable transport systems, defense, public safety and quality assurance in the Industry 4.0 are essential in a modern society. In a mission-critical scenario, a mission failure would jeopardize human lives and put at risk some other assets whose impairment or loss would significantly harm society or business results. Even small degradations of the communications supporting the mission could have large and possibly dire consequences. On the one hand, mission-critical organizations wish to utilize the most modern, disruptive and innovative communication systems and technologies, and yet, on the other hand, need to comply with strict requirements, which are very different to those of non critical scenarios. The aim of this thesis is to assess the feasibility of applying emerging technologies like Internet of Things (IoT), Cyber-Physical Systems (CPS) and 4G broadband communications in mission-critical scenarios along three key critical infrastructure sectors: transportation, defense and public safety, and shipbuilding. Regarding the transport sector, this thesis provides an understanding of the progress of communications technologies used for railways since the implantation of Global System for Mobile communications-Railways (GSM-R). The aim of this work is to envision the potential contribution of Long Term Evolution (LTE) to provide additional features that GSM-R would never support. Furthermore, the ability of Industrial IoT for revolutionizing the railway industry and confront today's challenges is presented. Moreover, a detailed review of the most common flaws found in Radio Frequency IDentification (RFID) based IoT systems is presented, including the latest attacks described in the literature. As a result, a novel methodology for auditing security and reverse engineering RFID communications in transport applications is introduced. The second sector selected is driven by new operational needs and the challenges that arise from modern military deployments. The strategic advantages of 4G broadband technologies massively deployed in civil scenarios are examined. Furthermore, this thesis analyzes the great potential for applying IoT technologies to revolutionize modern warfare and provide benefits similar to those in industry. It identifies scenarios where defense and public safety could leverage better commercial IoT capabilities to deliver greater survivability to the warfighter or first responders, while reducing costs and increasing operation efficiency and effectiveness. The last part is devoted to the shipbuilding industry. After defining the novel concept of Shipyard 4.0, how a shipyard pipe workshop works and what are the requirements for building a smart pipe system are described in detail. Furthermore, the foundations for enabling an affordable CPS for Shipyards 4.0 are presented. The CPS proposed consists of a network of beacons that continuously collect information about the location of the pipes. Its design allows shipyards to obtain more information on the pipes and to make better use of it. Moreover, it is indicated how to build a positioning system from scratch in an environment as harsh in terms of communications as a shipyard, showing an example of its architecture and implementation.[Resumen] En la sociedad moderna, los sistemas de transporte fiables, la defensa, la seguridad pública y el control de la calidad en la Industria 4.0 son esenciales. En un escenario de misión crítica, el fracaso de una misión pone en peligro vidas humanas y en riesgo otros activos cuyo deterioro o pérdida perjudicaría significativamente a la sociedad o a los resultados de una empresa. Incluso pequeñas degradaciones en las comunicaciones que apoyan la misión podrían tener importantes y posiblemente terribles consecuencias. Por un lado, las organizaciones de misión crítica desean utilizar los sistemas y tecnologías de comunicación más modernos, disruptivos e innovadores y, sin embargo, deben cumplir requisitos estrictos que son muy diferentes a los relativos a escenarios no críticos. El objetivo principal de esta tesis es evaluar la viabilidad de aplicar tecnologías emergentes como Internet of Things (IoT), Cyber-Physical Systems (CPS) y comunicaciones de banda ancha 4G en escenarios de misión crítica en tres sectores clave de infraestructura crítica: transporte, defensa y seguridad pública, y construcción naval. Respecto al sector del transporte, esta tesis permite comprender el progreso de las tecnologías de comunicación en el ámbito ferroviario desde la implantación de Global System for Mobile communications-Railway (GSM-R). El objetivo de este trabajo es analizar la contribución potencial de Long Term Evolution (LTE) para proporcionar características adicionales que GSM-R nunca podría soportar. Además, se presenta la capacidad de la IoT industrial para revolucionar la industria ferroviaria y afrontar los retos actuales. Asimismo, se estudian con detalle las vulnerabilidades más comunes de los sistemas IoT basados en Radio Frequency IDentification (RFID), incluyendo los últimos ataques descritos en la literatura. Como resultado, se presenta una metodología innovadora para realizar auditorías de seguridad e ingeniería inversa de las comunicaciones RFID en aplicaciones de transporte. El segundo sector elegido viene impulsado por las nuevas necesidades operacionales y los desafíos que surgen de los despliegues militares modernos. Para afrontarlos, se analizan las ventajas estratégicas de las tecnologías de banda ancha 4G masivamente desplegadas en escenarios civiles. Asimismo, esta tesis analiza el gran potencial de aplicación de las tecnologías IoT para revolucionar la guerra moderna y proporcionar beneficios similares a los alcanzados por la industria. Se identifican escenarios en los que la defensa y la seguridad pública podrían aprovechar mejor las capacidades comerciales de IoT para ofrecer una mayor capacidad de supervivencia al combatiente o a los servicios de emergencias, a la vez que reduce los costes y aumenta la eficiencia y efectividad de las operaciones. La última parte se dedica a la industria de construcción naval. Después de definir el novedoso concepto de Astillero 4.0, se describe en detalle cómo funciona el taller de tubería de astillero y cuáles son los requisitos para construir un sistema de tuberías inteligentes. Además, se presentan los fundamentos para posibilitar un CPS asequible para Astilleros 4.0. El CPS propuesto consiste en una red de balizas que continuamente recogen información sobre la ubicación de las tuberías. Su diseño permite a los astilleros obtener más información sobre las tuberías y hacer un mejor uso de las mismas. Asimismo, se indica cómo construir un sistema de posicionamiento desde cero en un entorno tan hostil en términos de comunicaciones, mostrando un ejemplo de su arquitectura e implementación

    Trabalho de projeto de mestrado, Engenharia Informática (Engenharia de Software) Universidade de Lisboa, Faculdade de Ciências, 2020The fast-growing human population is causing an ever-increasing trend of hyper urbanisation and globalisation, along with the popularisation of private cars to commute, which contributes to several environmental and health problems, for instance, high lev els of noise, congestion, and pollution. Hence, most cities are facilitating and enhancing commuting travel, thus, fostering the development of transportation. Today’s urban transport networks are part of the daily lives of millions of people around the world, and in this era of digitalisation, servicising, and cashless economy the public transportation must also readjust. Therefore, contactless bank cards will make it reasonable to travel by public transport. It will be the first time in Portugal that a contactless bank card enables public transport to be accessed, travelled and charged. Such a solution would encourage the contactless debit or credit card to be an alternative to the proprietary transit card, thereby helping to enhance the usability and accessibility of public transport. With the launch of the contactless solution in public transport, a metropolitan area in Portugal will very well integrate a growing list of the world’s major cities such as London, Singapore, Rio de Janeiro and New York. Moreover, new passengers gradually shift from maintaining a private car to the use of public transport means, which allows a diminution on the emission of fuel gases, and a reduction of the global pollution. In addition to that, public transport operators pains also decrease because proprietary cards are handled and managed by financial institutions, enabling the transport agencies to turn their attention to the core of their business, like the multi-modal mass transit and fare calculation. This pioneering project in Portugal involved several stakeholders, including Card4B, Visa, and Unicre. Accordingly, the project aimed to provide an open-loop model with con tactless and post-paid payments to integrate into the existing operation of transportation ticketing. Finally, the developed solution supports contactless transactions, and followed the “Contactless Specifications for Payment Systems”. Successfully, the delivered solution was certified with an EMV Level 3 Certification for both Visa PayWave and MasterCard Contactless transactions

    The knowledge of passenger flows between each origin–destination (OD) pair is a main requirement in public transport for service planning, design, operation, and monitoring, and is represented by OD matrices. Although they can be determined by traditional approaches (e.g., surveys, ride-check counts, and/or smartcard-based methods), the availability of new technologies and the proliferation of portable devices triggers an emerging interest in building OD matrices from the apps of bus operators. This research proposes the first framework for the estimation of OD matrices on transit networks by processing smartphone app call detail records (SACDRs). The framework is experimentally tested on a sample of 30 workdays of an Italian bus operator. The results are represented by easy-to-read control dashboards based on maps, which help quantify and visualise the OD matrices in the metropolitan area of Cagliari (Italy). The experimentation shows that the framework can properly estimate the number of trips for both origin and destination w.r.t. OD matrices built from household surveys: the mean absolute error is on average lower than five movements for 90% of the origins and 85% of the destinations

    Orientador : Prof. Dr. Robson SelemeDissertação (mestrado) - Universidade Federal do Paraná, Setor de Tecnologia, Programa de Pós-Graduação em Engenharia de Produção. Defesa: Curitiba, 29/05/2015Inclui referências : f. 128-135Resumo: Os sistemas de transportes urbanos causam grande impacto no desenvolvimento das cidades e na qualidade de vida de seus habitantes. Um planejamento operacional eficiente traz benefícios sociais e econômicos para seus usuários. Tais melhorias podem ser alcançadas por meio da obtenção de dados precisos a respeito dos deslocamentos da população no seu dia a dia e de técnicas e métodos que ajudam a identificar a origem e o destino das suas viagens. Nesta pesquisa foi realizado um teste-piloto e um estudo de caso cujo objetivo é o de demonstrar a viabilidade operacional e as vantagens e desvantagens da utilização de um sistema de Identificação por Radiofrequência de Ultra Frequência (RFID UHF) como uma técnica de coleta dos dados a ser usada em estudos de padrão de viagem e comportamento dos passageiros de transporte público por ônibus. Para a compreensão do tema foi realizada uma revisão bibliográfica sobre conceitos, métodos e tipos de pesquisas utilizados na área de transporte e sobre a composição, funcionamento e restrições da tecnologia de RFID. Em seguida, realizou-se um estudo de caso em uma linha de ônibus de Curitiba, cujas fontes de informação foram uma pesquisa documental, uma entrevista a especialista e uma pesquisa de campo. Nesta última foram coletados, analisados e comparados dados obtidos a partir de quatro fontes: contagem por observação, pesquisa embarcada por abordagem, sistema de bilhetagem eletrônica e catraca. Nesta etapa foram reunidas também informações técnicas e comportamentais para utilização na etapa seguinte. Um sistema de RFID UHF foi então instalado em um ônibus da linha Intercampi da UFPR onde realizaram-se testes de leitura com o ônibus parado e em movimento. A partir dos resultados gerados pelo teste foi possível identificar a origem e o destino de 61% das viagens realizadas pelos usuários que participaram da pesquisa. Concluiu-se que, apesar da necessidade de ajustes e melhorias, a coleta de dados por meio de um sistema RFID UHF possui vantagens sobre as demais técnicas tradicionais, tais como uma maior amostra, precisão e facilidade do tratamento dos dados e possibilidade de acompanhamento do fluxo de passageiros em tempo real.

Planejamento de sistemas de transporte.Abstract: Urban transport systems have great impact on the development of cities and the quality of life of its inhabitants. An efficient operational planning brings social and economic benefits for its users. Such improvements can be achieved by obtaining accurate data about the population shifts in their day-to-day and by techniques and methods that help to identify the origin and destination of their trips. In this research we conducted a a pilot test and a case study whose goal was to demonstrate the operational viability and the advantages and disadvantages of using a Radio Frequency Identification System of Ultra Frequency (UHF RFID) as a data collection technique to be used in trips patterns and behavior studies of public transport bus passengers.. For the understanding of the topic was conducted a literature review about concepts, methods and types of research used in the transport area and about the composition, functioning and restrictions of RFID technology. Then, a case study was conducted on a bus line of Curitiba, whose sources of information were a documentary research, an interview to an expert and a field research. In this last one, it were collected, analyzed and compared data from four sources: manual passenger counts using traffic checkers, on-board survey, electronic ticketing system and electronic registering fareboxes. In this step, it was assembled some technical and behavioral information to be used in the next step. A UHF RFID system was then installed in a bus that operated an Intercampi bus route from UFPR where some reading tests were conducted with the bus stopped and moving. From the results generated by this test, it was possible to identify the origin and the destination of 61% of trips made by users who participated in the survey. We conclude that, despite the need for adjustments and improvements, the data collection with the use of UHF RFID system has advantages over other traditional techniques, such as a larger sample, accuracy and ease of data processing and the possibility of monitoring passenger flow in real time.

    Get PDF
    Advances in the Internet of Things (IoT) and aviation sector have resulted in the emergence of smart airports. Services and systems powered by the IoT enable smart airports to have enhanced robustness, efficiency and control, governed by real-time monitoring and analytics. Smart sensors control the environmental conditions inside the airport, automate passenger-related actions and support airport security. However, these augmentations and automation introduce security threats to network systems of smart airports. Cyber-attackers demonstrated the susceptibility of IoT systems and networks to Advanced Persistent Threats (APT), due to hardware constraints, software flaws or IoT misconfigurations. With the increasing complexity of attacks, it is imperative to safeguard IoT networks of smart airports and ensure reliability of services, as cyber-attacks can have tremendous consequences such as disrupting networks, cancelling travel, or stealing sensitive information. There is a need to adopt and develop new Artificial Intelligence (AI)-enabled cyber-defence techniques for smart airports, which will address the challenges brought about by the incorporation of IoT systems to the airport business processes, and the constantly evolving nature of contemporary cyber-attacks. In this study, we present a holistic review of existing smart airport applications and services enabled by IoT sensors and systems. Additionally, we investigate several types of cyber defence tools including AI and data mining techniques, and analyse their strengths and weaknesses in the context of smart airports. Furthermore, we provide a classification of smart airport sub-systems based on their purpose and criticality and address cyber threats that can affect the security of smart airport\u27s networks
