Design of RFID Mutual Authentication Protocol Using Time Stamp

Nowadays, there are many active studies and applications of RFID authentication protocol. Because RFID communicates wirelessly without contacting a reader, its communicated information is more likely to be exposed compared to ordinary wired communication area. Communicated information can be easily eavesdropped by external attacks and such stolen information can be used for malicious purpose, which causes security accidents. In order to complement such weakness, countless RFID authentication protocols have been studied. However, they still have weaknesses in tracking, replay attack and spoofing. In this paper, a protocol has been designed which is safe from tracking, replay attack and spoofing using time stamp which is generated also in Back-End DB unlike other existing protocols.
