T he paper analyzed the security of a Radio Frequency Identification ( RFID ) authentication protocol based on Physically Unclonale Function (PUF ) and found it cannot resist de‐synchronization attack ,full disclosure attack by man‐in‐the‐middle attack .The paper described the details of these attacks and improved the protocol .The improved protocol can effectively avoid these attacks .Analysis of security and performance shows that the improved protocol can provide strong security and privacy with low cost .
