Design And Simulation Of Low-cost RFID Group-tag Authentication And Ownership Transfer Protocol

Radio frequency technology(Radio Frequency Identification,RFID for short)is a technology that can realize the automatic identification and data acquisition of objects without contact,which occupies an important position in the construction of the sensing layer of the Internet of Things.RFID technology has many advantages such as long-distance identification,long service life,good tolerance and so on.It has spread from the initial military applications to various industries.In recent years,RFID technology is no longer confined to single-tag forms.Especially in the supply chain environment,RFID group tags are more common.In order to ensure the security and privacy of RFID tags,the design of RFID group tag authentication and ownership transfer protocols is very important.In the existing RFID group tag authentication protocols,most of them cannot resist attacks such as desynchronization and replay.At the same time,there are disadvantages such as the need to introduce trusted third parties and the high cost of the tags.Therefore,designing a secure and low-cost RFID group tag authentication protocol is an issue that needs urgent research and solution.This paper first proposes an RFID group tag authentication protocol based on the hash function,which improves the authentication efficiency on the premise of ensuring security.The protocol introduces a key update flag,which improves the efficiency of background database when it needs to search key,thereby reducing the computational burden on the database.At the same time,the new and old keys are used to solve the desynchronization attack.Secondly,in terms of RFID group tag ownership transfer protocols,most existing protocols issue keys by introducing trusted third parties.This method can ensure the privacy and security of the new and old owners,but the system's deployment costs are relatively high.It also increases the difficulty of key management.This paper proposes an RFID group tag ownership transfer protocol that can guarantee the forward / backward security based on the quafratic residue.Based on mutual authentication,the agreement can effectively transfer ownership without requiring the original owner to leave the site.Formal analysis of the above two protocols based on BAN logic shows that both protocols are secure.The comparison between the protocol designed in this paper and the existing similar protocols shows that the protocol in this paper can achieve higher security under the constraints of low cost.In the above two protocols,the hash function used on the tag side is a lightweight Hash function GLUON-128 / 8.In this paper,functional simulation experiments and hardware resource analysis are performed.Simulation results show that this function requires less hardware resources and can be embedded in tags to meet the needs of low-cost passive tags.
