Abstract: RFID technology is widely used in today's society. However, due to the shortcomings of its security model,RFID technology is still not applied in some areas very well. We proposed a new RFID security model-RHZD multi prover model.It can compensate for deficiencies in the original model. We also proposed a security protocol based on this model. It can solve many RFID security problems, such as cloning attack, replay attack, tag tracking, and etc.

Key words: RFID,Security model,Identification authentication,Security protocol
