An Efficient RFID Tag-Reader Mutual Authentication Scheme

Performing tag-reader mutual authentication to detect cloned fake tags and ward off malicious readers is a basic requirement of various applications of RFID technology. In this paper, we propose an efficient RFID tag-reader mutual authentication scheme that is light weight, simple to implement and can effectively alleviates tracking and replaying threats. This scheme also has good performance and scalability features and can support efficient ownership management of the RFID tag attached objects.
