Through the research on security and calculation cost and other factors of authentication protocol base on hash function in lightweight radio frequency identification( RFID) system,the security defects and computational cost of this kind of protocol are analyzed. Through the improvement of the protocol,a kind of lightweight RFID mutual authentication protocol is proposed. When it meets the condition of the same security property,the calculation cost of the tag is reduced,and the calculation performance of the tag is improved. And the safety certification process of the protocol is proved through the BAN logic formalization. Then through the experiment of the 51 ECU and antenna module to copy electronic tag,it was compared with other protocols which based on Hash function from the security,privacy,agreement and other factors. The experiments show,the authentication process time of this protocol is shorter,and the more tags in the database,the better superiority of the improved protocol's calculate cost. So,this protocol has a certain practical value.
