Advanced Communications Specific Emitter Identification

Radio Frequency Identi cation (RFID) tags are used to track inventory and for automatic recognition of ID cards and passports. Reproduction of the electronic equivalent of an RFID chip, commonly known as RFID cloning, is a straightforward process and can lead to serious security breaches. A cloned RFID badge can allow for unauthorized access to secured areas. Speci c Emitter Identi cation (SEI) uses unintentional modulations of the electromagnetic signal of RF emitters to identify individual sources of signals, and allows for the detection of cloning of RF chips. A method for determining a spoofed RFID tag from the original RFID tag based on SEI is presented here. Features are extracted using the Dynamic Wavelet Fingerprint (DWFP) and supervised pattern classi cation techniques are used to identify the unique RFID tags.
