Intrusion detection in RFID systems

In recent years, advances in Radio Frequency identification (RFID) technology has led to their widespread adoption in diverse applications such as object identification, access authorization, environmental monitoring and supply chain management. Although the increased proliferation of tags enables new applications, they also raise many unique and potentially serious security and privacy concerns. Security solutions in RFID systems need to be strengthened to ensure information integrity and to prevent hackers from exploiting the sensitive tag data. In this paper, we address the importance of intrusion detection security paradigm for RFID systems. We present an overview of state of the art in RFID security and investigate the limitations of traditional security solutions based on cryptographic primitives and protocols. We propose an RFID intrusion detection model that integrates information from RFID reader layer and middleware layer to detect anomalous behavior in the network, thus improving their resilience to security attacks.
