Security issues become more and more significant in RFID development. Recently, Chien proposed an ultralightweight RFID authentication protocol in order to achieve privacy and authenticity with limited computation and transmission resources. However, we find two desynchronization attacks to break the protocol. In order to repair the protocol, two patches that slightly modify the protocol are presented in the paper.
