Multiple Loop Antenna against Skimming Attack

In this paper, new models of antennas are studied and implemented in order to prevent RFID passive cards from skimming attacks. Their effectiveness is proved thanks to measurement confirming the simulation tools prediction. With our countermeasure antenna design, an RFID card cannot be easily skimmed, without a well positioning of the skimmer, even in short ranges (<;10 cm). Beyond this distance, attacks become unrealistic.
