Cloning attacks threaten Radio-Frequency IDentification (RFID) applications but are hard to prevent. Existing cloning attack detection methods are enslaved to the knowledge of tag IDentifiers (IDs). Tag IDs, however, should be protected to enable and secure privacy-sensitive applications in anonymous RFID systems. In a first step, this paper tackles cloning attack detection in anonymous RFID systems without requiring tag IDs as a priori. To this end, the authors leverage un-reconciled collisions to uncover cloning attacks.
