High-Efficient RFID Authentication Protocol Based on Physical Unclonable Function

RFID(Radio Frequency Identification) is an increasingly popular technology that uses radio signals for object identification. Tracking and authentication in RFID tags have raised many privacy and security concerns.Known privacy and security cryptographic defenses are too hardware-expensive to incorporate into low-cost RFID tags.This paper presents a low-cost and efficiency security protocol based on Physical Unclonable Functions(PUF), which solved the problems of existing security authentication protocol and can resist eavesdropping attack, replay attack, physical attack and tracking attack, with forward-security and backward-security.
