Der volle Inhalt der QuelleNear Field Communication (NFC) is a standardized communication technology derived from Radio Frequency Identification (RFID). NFC uses magnetic induction between two antennas in order to transfer data and/or energy between two electronic devices. NFC operating frequency is 13.56 MHz.Due to the wide range of devices and applications, a predefinition of antenna geometry and corresponding electrical parameters is difficult. In fact, each device shows different antennaphysical characteristics ; On the Other hand, the NFC control integrated circuit (IC) is generic and does not depend on antenna nor a device. Therefore, each integrator associates the NFC IC with a specific antenna for each device. Current NFC transmission modules require the antenna circuitry to be matched with the integrated circuit. Nowadays, the matching is performed manually using a time consuming iterative procedure for each device. Moreover, the matchingcan be done only once at the device design level, regardless of the communication mode (reader, card or peer-to-peer) and regardless of the secondary device influence on the primary antenna characteristics.In this manuscript, we propose a detailed description of the electrical performances of NFC Systems. Then an accurate and complete analytical electrical model of NFC antennas is proposed.Finally, we develop a new technic of automatic adaptation of the matching network in order to optimize the electrical performances in the transmission phase in terms of energy transfer from the reader to the transponder

Der volle Inhalt der QuelleThe open innovation movement, which has been emerging since the early 21th century, is at the origin of the emergence of business ecosystems (BE). They integrate players who have their competences and their roles co-evolving to manage the challenges of each stage of their life cycles. But few studies consider this dynamic dimension of the BE and especially its first stage: the birth. Specifically, it evolves along an innovation trajectory which leads the actions to define a new offer. Based on qualitative research and on process approach, this study focuses on the case of the emergence of a business ecosystem in the field of contactless mobile services. We conduct a multilevel analysis through the global process of this BE's innovation trajectory and the local process of the experimental projects which are articulated along this path. We are 'coking at these two processes as places, which include a managerial logic contributing to build key competences and a socio-political logic providing power strategies between players and their roles definition. Our results focus on two analytical levels. At the global level, the main challenge is to define a shared collective vision. It revolves around two dimensions: a technical dimension (the dominant design) and an economic dimension (the business model). It is formalized through key competences building which, in turn, defines the roles of the members. In this dynamic, competences related to "use context sensitivity" are crucial: they enable BE's intégration until the trajectory lock-in, then its efficiency through the generation of new alternatives which may lead to some bifurcations (positive ambiguity). At the local level, experimental projects promote the confrontation of individuals' strategies. They generate the building of competences which capitalize along the trajectory or question the collective vision

Der volle Inhalt der QuelleIn 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

Der volle Inhalt der QuelleVirtualization was originally introduced in networks to reduce maintenance and deployment costs. It has experienced tremendous growth and reshaped the landscape of IT and ITC networks. Virtualization permits the sharing of physical resources for instantiating isolated virtual machines despite the fact that it is drawing its resources from the same physical hardware. More recently NFV (Network Functions Virtualization) appeared, it allows to virtualize entire classes of network functions node in blocks that can connect to create communication services. In this thesis we virtualize the access network nodes, namely Wi-Fi access points. The Wi-Fi became one of the hot-topic technology for mobile operators, it allows them to offload some of the customers’ data traffic via hotspots. The problem that arises in such a mechanism is the existing wireless standards, and mobile devices connection management software have not been developed for this purpose. The Hotspot2.0 standard was created to overcome this limitation, by making the Wi-Fi experience similar to the cellular in terms of roaming, transparency and security. We have in our work, applied the concept of NFV by virtualizing these brand new Wi-Fi access points. One of the problems that we faced is the high security required by such standard, including the provisioning of client credentials in public areas. In our thesis we propose an innovative architecture for the repatriation of these credentials through NFC terminals. These same terminals will be used for access points’ urbanization by allowing users to create their own Wi-Fi virtual access point on the fly. The last aspect of this thesis is related to the management of virtualized entities changing communication patterns of legacy networks. In this context, SDN (Software Defined Network) emerged in data centers to redefine the way we think about networks, and is designed for virtualized environments. In this thesis we brought SDN to the edge of the network in our Wi-Fi virtual access points. More than a new paradigm of networks communications, we will see that NFV/SDN in Wi-Fi networks will in the near future make Wi-Fi networks more flexible, open and scalable

Der volle Inhalt der QuelleEMV is the standard implemented to secure the communication, between a client’s payment device and a PoS, during a contact or NFC purchase transaction. It represents a set of security messages, exchanged between the transaction actors, guaranteeing several important security properties. Indeed, researchers in various studies, have analyzed the operation of this standard in order to verify its reliability: unfortunately, they have identified several security vulnerabilities that, today, represent major risks for our day to day safety. Consequently, in this thesis, we are interested in proposing new solutions that improve the reliability of this standard. In the first stage, we introduce an overview of the EMV security payment system and we survey its vulnerabilities identified in literature. In particular, there are two EMV security vulnerabilities that lead to dangerous risks threatening both clients and merchants: (1) the confidentiality of banking data is not guaranteed, (2) the authentication of the PoS is not ensured to the client’s device. Therefore, our interests move in the second stage to address these two weaknesses. We first review a selection of the related works that have been implemented to solve these vulnerabilities, and then, in order to obtain better results than the related works, we propose a new secure contact and NFC payment system that includes four innovative security mechanisms. Finally, in the third stage, we adapt our first security mechanism in the context of a new NFC payment architecture. This architecture is especially destined for small merchants, allowing them to take advantage of their NFC smartphones for use directly as NFC readers

Der volle Inhalt der QuelleWith the emergence of near-field technology (NFC), mobile terminal have become a true instrument of contactless payment. This type of system is a new opportunity to boost the electronic payment systems (EPS) for the micropayment. The objective of this research is to develop a model and measurement tools to handle and to identify factors influencing the acceptance of these systems. Based on the paradigms of the acceptance of technology and research around the SPE, we have developed a conceptual model which integrates the UTAUT and TTF. This model allows both to consider the adoption strategies of individuals and their intention to adopt. Indeed, perceived usefulness, perceived ease of use and facilitating conditions are no longer sufficient for a technology to be adopted. The capabilities of this technology have to match the tasks that the user will perform. Our result have been measured and validated thanks to structural equations analysis of data collected from a sample of 629 individuals
