Classification of major security attacks against RFID systems

Thanks to their crucial role in different areas such as supply chain and healthcare, Radio Frequency Identification (RFID) technologies have currently attracted a lot of attention. They are mainly used for identifying objects and people based on a combination of tags and readers. Nevertheless, this identification brings out many challenges and concerns including security which still remains an open issue. In this work, we present a survey of recent works dealing with security and privacy in RFID systems. Particularly, we compare and classify them according to which part of RFID system each solution could be applied, taking into account different requirements and parameters including their conformity to RFID standards. Hence, our comparative study targets to provide a wide and clear vision of these concerns as a dashboard to help determining the most appropriate solutions towards any security problem.
