RFID Security Protocol by Lightweight ECC Algorithm

A radio-frequency identification (RFID) system has been gradually expending its application areas. However, RFID had a serious security problem likeas attacker´s tracing and spoofing. Especially, LowcostRFID tags are weak device and have limitedcomputing power. Therefore, an RFID securityprotocol has been light weighted.In this paper, we design a lightweight RFID securityprotocol based on the ID Blind Scheme and ECC(Elliptic Curve Cryptography). Our protocol offersenhanced security feature in RFID security withrespect to user privacy against tag cloning allowing anadditional ECC modular operation.
