In the last decade, Radio Frequency IDentification (RFID) systems are employed in many authentications and identifications applications. In RFID systems, in order to provide secure authentication between RFID users, different authentication protocols proposed. In 2011, the researcher proposed a Hash-based mutual RFID Authentication Protocol (HRAP). They claimed that HRAP protocol provides secure communication between RFID users and also it can provide users privacy. In that year, researcher investigated the security and privacy of HRAP protocol and showed that HRAP protocol has some weaknesses.
