A Card Emulation Technique based Secure Framework for Internet of Things (IoTs) Applications

IoT (Internet of Things) enables the devices to be smartly connected with each other to share the data and collect it for future analysis. With the expansion of time, the applications of IoT are increasing in every sector of society like homes, devices, vehicles, health sector, and many more. The wireless communication inIoT makes use of different wireless communication protocol, one such protocol is NFC. The card emulation technique in NFC is widely used in payment sector and research is in progress to enhance its application area. Smart cards in IoT are used to store the keys and user identification information to provide an easy way to authenticate users and provide them the service. In this paper, we will represent a communication protocol between an IoT device and the user smart phone using card emulation technique that can be used in many sectors of IoT. The protocol will eliminate the use of smart cards in IoT by providing users with virtual cards that can be stored and accessed with smart phone. The protocol provides an authorization facility of user, and controls the access of illegitimate user.
