Secure and Privacy-Preserving RFID Authentication Scheme for Internet of Things Applications

Abstract

Privacy issue has become a crucial concern in internet of things (IoT) applications ranging from home appliances to vehicular networks. RFID system has found enormous scope in IoT applications such as consumer electronics, healthcare, tracking objects and transport system. In this paper, we present a privacy preserving authentication protocol for RFID system. The protocol provides mutual authentication of tag and reader, and preserves privacy of tags. We analyze the proposed protocol against active adversary and show that the protocol preserves narrow-strong privacy of the tags. We compare our protocol with the related work and show its usefulness in wide range of IoT applications.
