De-synchronization Attack on Quadratic Residues-Based RFID Ownership Transfer

Radio Frequency Identification (RFID) ownership transfer protocol aims at securely updating RFID tag´s internal state and key such that only the current owner of a tag is allowed to access the tag when it is transferred from one owner to the next. Doss et al. [32] proposed two very promising RFID ownership transfer protocols which represented state of the art and were claimed to own excellent security performance and computational performance. However, we will show our de-synchronization attack on these protocols.
