An authentication protocol in mobile RFID environment

RFIDs have been popularly used in daily life. To avoid being intruded on user privacy, proper protection is necessary. The privacy issues, such as object tracking and forgery of tags, are widely studied in the literature. Traditionally, the reader is regarded as a part of the system. In mobile RFID environment, however, anyone who holds the reader can connect to the server and acquire other information about the objects he owns. To verify whether a reader has the rights to access the tags has become essential. In this paper, we propose an RFID authentication protocol that can achieve the above goal and provide tag anonymity and forgery resistance. Hence, the user privacy is guaranteed.
