Near Field Communication (NFC) is a technology which has found wide use in recent years in Mobile Sector. NFC enables your mobile handset to become your secure wallet and it also converts your mobile to a device that easily communicates with NFC tags in a contactless way to trigger any desired action such as approving your credit card payment without requiring you to type your pin number. The Secure Element is a component in NFC which is a tamper-resistant device used to store sensitive user credentials (such as your private keys, or remaining credit amount) and guaranteeing that unauthorized people/applications cannot retrieve/modify them. That's why an NFC phone can be used as a credit card holder as well. However, having a Secure Element inside a phone requires the management of that sensitive device which leads to many problems such as remote issuance, authorization management, and secure key handling. This paper examines and suggests a cloud based financial transaction execution method for NFC using an online secure element. Our experimental results show that thanks to the 4G Internet speed, having an online connection during a transaction is fast enough to compensate for the delays caused by the execution of cryptographic operations inside the secure element.

Design of a context aware security model for preventing relay attacks using NFC enabled mobile devices
Çavdar, Davut; Betin Can, Aysu; Department of Information Systems (2020)
Near Field Communication (NFC) is a promising communication technology used in smart mobile devices. As an effective and flexible communication technology, NFC is frequently used in innovative solutions nowadays such as payment, access control etc. Because of the nature of these transactions, security is an important issue since NFC is used in critical applications such as payment and access control. There are several attacks mentioned in literature against NFC-enabled applications, yet, none of the securit...
RONFC: A Novel Enabler-Independent NFC Protocol for Mobile Transactions
Turk, Ismail; Angın, Pelin; Cosar, Ahmet (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
The use of near field communication (NFC) technology for contactless mobile transactions has become popular in the past decade with the availability of this technology in mobile devices. Today, there are millions of the NFC-enabled mobile handsets in the market, with mobile handset manufacturers and mobile network operators enabling m-wallet solutions using the secure elements (SEs) that they own, thus can remotely control, on the devices. While this approach gives full control to the SE owner to activate a...

Cavdar, D.; Tomur, E. (2015-05-29)
In this study, a practical card-emulated relay attack is implemented on Near Field Communication (NFC) equipped mobile devices. NFC is a promising communication technology which is also used in smart mobile devices. As an effective and flexible communication technology, NFC is frequently used in innovative solutions nowadays such as payments, access control etc. Because of the nature of these transactions, security is a critical issue that should be considered in system design and development phases. Althou...
Internet Connection Sharing Through NFC for Connection Loss Problem in Internet-of-Things Devices
Turk, Ismail; Coşar, Ahmet (2015-08-28)
Contactless devices and smart cards have been widely in use in daily life transactions for a long time. At first, those systems were designed to work fully offline for both the reader and the card side. With technological improvements, Internet connection can be available even in very small embedded devices (IoT devices). As a result, current systems have connected devices as a part of the transaction design and so keeping the system operational all the time relies on the availability of continuous Internet...
An Open, NFC Enabler Independent Mobile Payment and Identification Method: NFC Feature Box
Turk, Ismail; Coşar, Ahmet (2016-06-24)
The use of Mobile Devices for electronic payment has increased significantly in the last decade. Near Field Communication (NFC) mobile payment is gaining popularity and it is widely considered to be the technology that will turn smartphones into m-wallets. While a typical wallet contains identification, loyalty, public transport and credit cards, m-wallet solutions currently have well-defined standards for credit card enrollment and usage only. In this thesis, we explore and present the main reason for this...
