QSNFC: Quick and secured near field communication for the Internet of Things

Near Field Communication (NFC) is used for a wide range of security-critical applications such as payment or access control. Although such applications require secured data transfer, the NFC protocol does not include transport layer security. Other protocols that are built on top of NFC, such as the NFC data exchange format (NDEF), only provide insufficient security measures. Therefore, implemented security solutions are often application specific and do not follow well-established standards. To facilitate NFC usage in the Internet of Things (IoT) where millions of devices need to be secured, an efficient and sufficiently secured NFC-based protocol needs to be developed. In this paper, we present the Quick and Secured NFC (QSNFC) protocol. Our protocol is capable of performing more efficient key agreements for recurring connections, and thus, can be used as an efficient alternative to the Transport Layer Security (TLS) protocol.
