Abstract
The Internet of Things (IoT) aims to achieve the interconnection of all devices in our lives. Due to the complex network environment, the IoT with mobile devices often faces many security problems, such as privacy leakages and identity forgery attacks. As a developing technology in mobile IoT, near field communication (NFC) is widely used in electronic payments and identity authentications. The current NFC studies mainly focus on payment technology, but there are a few studies on privacy protection and the lightweight requirements in the mobile IoT authentication protocol. We focus on the lightweight privacy protection authentication technology in mobile IoT. In the paper, we summarize the clustering model in mobile IoT networks and propose a lightweight authentication protocol. A security analysis shows that the protocol can resist many security threats, such as privacy leakages, identity forgeries, and replay attacks. The simulation also shows that the protocol is lightweight, with the utilization of look-up-tables (LUTs) and registers in our protocol being less than 0.5%. Our work can provide a secure and lightweight mobile authentication serve in the NFC-based mobile IoT network such as smart home and office attendance.

Summary
With the rapid development of the Internet of Things (IoT), many researchers have focused on security and privacy protection. Radio frequency identification (RFID) technology is used to achieve mutual authentication and communication between devices in the IoT [1]. Near Field Communication (NFC) is a new and developing communication technology, which is often used in mobile IoT network. It primarily works in the 13.56 MHz band with a data transmission speed of 106–424 kbps. The motivation of our study of NFC authentication protocol is the security requirement and communication overhead during the authentication in mobile IoT networks. We propose a new lightweight NFC identity authentication protocol for mobile NFC IoT networks. The protocol achieves tag anonymity and the mutual authentication of the IoT system
