Yayın NFC loyal system on the cloud(IEEE Computer Society, 2013) Coşkun, Vedat; Özdenizci Köse, Büşra; Ok, Kerem; Alsadi, MohammedFC (Near Field Communication) technology facilitates mobile phone usage of billions of people throughout the world that offers diverse services ranging from payment and loyalty applications to access keys for offices and houses. NFC technology is one promising technology that have adopted smart card as secure element (SE) to provide a secure area for the execution of multiple applications and storing sensitive data. In this paper, we developed a framework to integrate NFC loyal system onto the cloud. We adapted NFC mobiles together with their SE to the cloud (Infrastructure as a Service - IaaS) using Cloud Computing methodology.Yayın Design of a key exchange protocol between SIM card and service provider(Institute of Electrical and Electronics Engineers Inc., 2015-11-05) Ok, Kerem; Coşkun, Vedat; Çevikbaş, Cem; Özdenizci Köse, BüşraCurrent capabilities of smart cards, Smartphones, and cellular network provoke companies to provide vast amount of services to the mobile users. Some of those services require end-to-end encryption between a Service Provider and a SIM card. Keyed SIM cards already contain the required structure for secure key generation and upload, whereas un-keyed SIM cards do not have the required capability for this. In this paper, we provide a key exchange protocol, which creates a symmetric key by the collaborative work of SIM card and the Service Provider server. After a successful protocol run, SIM card and Service Provider can perform end-to-end data encryption.
