Yayın A tokenization-based communication architecture for HCE-Enabled NFC services(Hindawi Publishing Cor, 2016) Özdenizci Köse, Büşra; Ok, Kerem; Coşkun, VedatFollowing the announcement of Host Card Emulation (HCE) technology, card emulation mode based Near Field Communication (NFC) services have gained further appreciation as an enabler of the Cloud-based Secure Element (SE) concept. A comprehensive and complete architecture with a centralized and feasible business model for diverse HCE-based NFC services will be highly appreciated, particularly by Service Providers and users. To satisfy the need in this new emerging research area, a Tokenization-based communication architecture for HCE-based NFC services is presented in this paper. Our architecture proposes Two-Phased Tokenization to enable the identity management of both user and Service Provider. NFC Smartphone users can store, manage, and make use of their sensitive data on the Cloud for NFC services; Service Providers can also provide diverse card emulation NFC services easily through the proposed architecture. In this paper, we initially present the Two-Phased Tokenization model and then validate the proposed architecture by providing a case study on access control. We further evaluate the usability aspect in terms of an authentication scheme. We then discuss the ecosystem and business model comprised of the proposed architecture and emphasize the contributions to ecosystem actors. Finally, suggestions are provided for data protection in transit and at rest.Yayın Current benefits and future directions of NFC services(IEEE, 2010) Ok, Kerem; Coşkun, Vedat; Aydın, Mehmet Nafiz; Özdenizci Köse, BüşraNear Field Communication (NFC), as an emerging and promising technology, is an integration of Radio Frequency Identification (RFID) technology with mobile devices. NFC-enabled mobile devices can act as contactless smart cards and are also capable to read and write data from/to those cards. Research endeavours concerning NFC appear to focus mainly on development of NFC enabled services and applications. On the other hand, benefits and underlying values associated with different NFC applications' service is not yet well elaborated. In this paper we examined existing NFC applications, prototypes and studies from both academia and industry. We analyzed these applications by classifying them into NFC operating modes to surface the nature of underlying value-added services and benefits that they provide. Moreover we emphasized possible future usage scenarios together with directions and questions for future research based on the identified benefits.
