Intrusion Detection Methods Based on Incomplete RFID Traces

According to the Radio frequency identification (RFID) tag cloning attack problems of RFID system and the existing problems of intrusion detection research based on incomplete RFID traces, this paper proposes a method of intrusion detection by combining the Markov chain technology and probability statistics technology. We use this method to calculate the threshold that is used to determine whether the tag event is a cloning tag intrusion one. Current research focuses on RFID intrusion detection under the condition of complete RFID traces, such as encryption algorithm improvement, tag authentication protocol improvement, and track and trace technology in RFID supply chain. RFID traces are occasionally to be incomplete, which causes the above methods to be inefficient. Our method proposed in this paper is the solution to incomplete RFID traces which makes up for the study of RFID intrusion detection research.
