In this paper, the RFID system security requirements and the existing lack of security authentication protocol RFID Bi-direction authentication protocol based on variable update. Hash function characteristics, mutual authentication in RFID systems, effectively preventing the counterfeiting phenomenon within the system, while using the system initial value cycle update, enhance the level of security certification to overcome a variety of security attacks.
