Introduction

Abstract

Internet of Things (IoT) is a new networking paradigm for cyber-physical systems that allow physical objects to collect and exchange data. Generally, every physical object in the IoT needs to be uniquely identified by some auto-ID technologies. Radio Frequency Identification (RFID) tags have been widely used as object identifiers for IoT. The widespread use of RFID tags in IoT brings about new issues on efficiency, security, and privacy, which in turn opens up new research opportunities. This book presents several RFID protocols that are designed to improve the efficiency, security, and privacy of the IoT.
