RFID Intrusion Detection with Finite Automation

Based on the characteristics of RIFD middleware, the paper adds an intrusion detection system in RFID middleware to gather the feature vector from the comparison between intrusion data stream with RIFD internal data stream and establish finite automation according to intrusion data steam corresponding to sub-module. The efficiency of the intrusion detection system is improved via the consolidation of some of finite automation. Besides, the proposed system can achieve the classification of RFID attacks from finite automation, and even detect some unknown attacks through analyzing the nature of the attacks. By randomizing the order of access events which has mixed attack events in fixed proportion, the system can achieve stable detection rates in 3 rounds tests.
