Vers un environnement logiciel générique et ouvert pour le développement d'applications NFC sécurisées / Towards a generic and open software environment for the development of Secure NFC applications

Lesas, Anne-Marie 14 September 2017 (has links)
Dans le domaine des transactions et du paiement électronique avec une carte à puce, le standard de communication en champ proche « Near Field Communication » (NFC) s’est imposé comme la technologie des transactions sans contact mobiles sécurisées pour le paiement, le contrôle d’accès, ou l’authentification. Les services sans contact mobiles sécurisés sont basés sur le mode émulation de carte du standard NFC qui implique une composante matérielle à accès restreint de type carte à puce appelée « Secure Element » (SE) dans laquelle sont stockées les données confidentielles et les fonctions sensibles. Malgré les efforts de standardisation de l'écosystème, les modèles proposés pour la mise en œuvre du SE sont complexes et souffrent du manque de généricité, à la fois pour offrir des mécanismes d’abstraction, pour le développement d’applications de haut niveau, et pour la mise en œuvre et la vérification des contraintes de sécurité des applications.L’objectif de la thèse est de concevoir et réaliser un environnement logiciel basé sur un modèle générique compatible avec les standards établis et peu sensible aux évolutions technologiques. Cet environnement devrait permettre à des non-experts de développer des applications multiplateformes, multimodes, multi-facteurs de forme, qui s’interfacent avec le SE dans un smartphone NFC. / In the field of electronic transactions and payment with a smart card, the Near Field Communication (NFC) standard has stood out against other candidate technologies for secure mobile contactless transactions for payment, access control, or authentication. Secure mobile contactless services are based on the card emulation mode of the NFC standard which involves a smart card type component with restricted access called "Secure Element" (SE) in which sensitive data and sensitive functions are securely stored and run. Despite considerable standardization efforts around the SE ecosystem, the proposed models for the implementation of SE are complex and suffer from the lack of genericity, both to offer abstraction mechanisms, for the development of high-level applications, and for the implementation and verification of applications security constraints.The objective of the thesis is to design and realize a software environment based on a generic model that complies with established standards and which is not very sensitive to technological evolutions. This environment should enable non-experts to develop multi-platform, multi-mode, multi-factor SE-based applications running into the NFC smartphone.

Dosis: din smarta pillerdosa : Utveckling av ett inbyggt system för en dosettask / Dosis: your smart pill dispenser : Development of an embedded system for a pilldispenser

Kleyer, Oskar, Holmlund, Fredrik January 2018 (has links)
Modern medicinering medför att patienter kan behandlas mer effektivt om den tas pårätt sätt. När patienter själva ansvarar för sin medicinering kan den feldoseras ellerglömmas bort, vilket ändrar förutsättningar för dess inverkan. Glömska kombineradmed sinnesnedsättningar försvårar för patienten att sköta sin medicinering.Lösningen på detta problem är idag utökad hemvård där vårdpersonal hjälper patientenatt ta rätt medicin vid rätt tidpunkt. En teknisk lösning kan vara ett inbyggt systemsom påminner patienten, sparar missade doseringar och kan därmed ge mer informationtill läkare som då kan göra mer välgrundade beslut för fortsatt vård.Resultaten visar att en dosettask kan användas för att påminna patienter att ta sinmedicin och skicka missad dosering med närfältskommunikation. Som mikrokontrolleranvändes en STM32 Nucleo, med en tillståndsmaskin som mjukvarulösning. I vidarestudier kan ett realtidsoperativsystem användas. Systemet programmerades medArduinos utvecklingsmiljö, men ett alternativ är IAR. Projektets prototyp kunde medde flesta modulerna uppnå specifikationens batteritid, utöver ljudmodulen som användes.För att komma fram till detta resultat skapades två teoretiska extremfall därprototypen testades.Dosettasken kan leda till minskat pillersvinn och en lägre kostnad då färre hembesökkrävs. Dessutom resulterar detta i ökad självständighet för patienten. Dessa faktorerleder till att dosettasken bidrar till en ökad hållbar utveckling. / Modern medication allows patients to be treated more efficiently if taken properly.When patients themselves are responsible for their medication, it can be wronglydosed or forgotten, which changes the conditions for its effects. Forgetfulness combinedwith impaired senses make it difficult for the patient to take care of his medication.The solution to this problem today is increased home care, where healthcare professionalshelp patients to take the right medication at the right time. A technical solutioncan be an embedded system that reminds the patient, saves missed dosages, and canprovide more information to doctors who can make more informed decisions for furthercare.The results show that a pill dispenser can be used to remind patients to take their medicationand send missed dosages with near field communication. As a microcontroller,a STM32 Nucleo was used, with a state machine as software solution. In further studies,a real-time operating system can be used. The system was programmed with Arduino'sdevelopment environment, but an alternative is IAR. The prototype of the projectcould achieve the specifications battery life with most modules, except to thesound module used. To achieve this result, two theoretical extremes were created inwhich the prototype was tested.The pill dispenser can lead to reduced waste of pills and a lower cost, as fewer homevisits are required. In addition, this results in increased independence for the patient.These factors cause the pill dispenser to contribute to increased sustainable development.

Mobile Reisebegleitung mit NFC-Unterstützung

Pfanstiel, Jörn, Keller, Christine, Funke, Alexandra, Heinig, Tristan, Schlegel, Thomas 14 December 2012 (has links) (PDF)
Die zunehmende Nutzung [1] persönlicher mobiler Geräte durch immer mehr Fahrgäste des öffentlichen Personenverkehrs (ÖPV) begünstigt die Entwicklung neuer Applikationen, die den allgegenwärtigen Zugriff auf domänenspezifische Inhalte und Echtzeitdaten über variable Schnittstellen und Informationskanäle realisieren. Near Field Communication (NFC) gilt in diesem Zusammenhang als eine vielversprechende Technologie, die neben kontaktloser Datenübertragung auch Bezahlvorgänge direkt über das mobile Endgerät ermöglicht. Mit Blick auf die unterschiedlichen Einsatzmöglichkeiten von NFC in der mobilen Reisebegleitung wird in diesem Beitrag eine ikonografische Klassifikation für die visualisierte Analyse von Anwendungsszenarien vorgestellt, welche zur Planung ubiquitärer Applikationen im ÖPV eingesetzt werden kann.

行動支付之探討-以電信運營商為例

陳忠義 Unknown Date (has links)
由於智慧型手機與各種手持裝置日漸普及,4G行動上網速度與行動支付安全性、便利性與即時性的提升,行動支付(Mobile Payment)在這幾年已然成為電信、金融、手機軟硬體製造產業之間最熱門的話題之一,多樣化之支付型態因應而生。將個人行動裝置結合金融支付工具進行交易,讓使用者不需帶錢包出門即能輕鬆完成小額支付是未來趨勢,世界各國行動支付的比例逐漸提高,邁入無現金社會。 台灣電信運營商也積極在行動支付戰場爭取一席之地,陸續推出電信運營商帳單代付(Direct Carrier Billing,DCB)及近距離無線通訊(Near Field Communication,NFC)相關行動支付應用服務,以增加創新服務體驗及客戶黏著度,最終目標為提高客戶平均貢獻度(Average Revenue Per User,ARPU)。 本研究採用質性研究方法,透過次級資料蒐集、整理及分析,瞭解國外電信運營商之成功案例從中擷取鑑往知來的想法和做法,再深入觀察目前國內電信運營商在DCB的壞帳風險過高的問題及NFC電子錢包等行動支付之發展現況與窘境。最後提出建議,建議一為推動成立「電信聯合徵信中心」以共同降低壞帳風險,同時針對DCB用戶之消費項目進行分析以精準行銷並提升ARPU;建議二為推廣以「行動號碼」為數位身份認證(Mobile Connect)之行動支付平台,不僅可增加電信運營商之營收,更能夠滿足消費者追求快速、便利、安全性的需求。 / With the increasing popularity of smart phones and handheld devices, The 4G high mobility speeds and the security, convenience and real-time of mobile payment were improved. In recent years Mobile Payments have become a hot topic between the telecommunications, financial industry, mobile hardware and software manufacturing industry, diversified payment patterns in response. It is the future trend to combine personal mobile devices with financial payments tools so that users can easily make small payment no need to bring their wallet. The proportion of the Mobile Payment by countries in the world is gradually increasing and moving towards a cashless society. Taiwan's telecom operators are also preparing to carve out a niche for themselves in the mobile payment battlefield by launching Direct Carrier Billing (DCB)and Near Field Communication(NFC)related mobile payment application service to increase innovative service experience and customer adhesion, The ultimate goal is to enhance their Average Revenue Per User(ARPU). This research uses Qualitative Research Methods by collect, collate and analyze secondary data to understand the ideas and practices of observing the successful cases of foreign telecom operators to capture from the past to further understanding and solutions. And in-depth observation of the current domestic telecom operator’s highly bad debt risk in DCB and development situation and dilemma of the NFC related mobile payments. Finally, suggestion one is to facilitate the establishment of "Telecom’s Joint Credit Information Center" to reduce the risk of bad debts and then analyze the consumption items of DCB subscribers for precise marketing to enhance ARPU. Suggestion two is to promote “Mobile Connect” digital authentication solution with “Mobile Directory Number” in mobile payment’s platform. It not only increases the revenue of telecom operators, but also satisfy needs of consumer’s about seeking fast, convenient and safe.
