Research And Implementation Of A New Lightweight RFID System Security Protocol

With the further development of the Internet of Things,radio frequency identification(RFID)technology has been widely used.Specific scenarios include commodity supply chains and military investigations.RFID systems typically use electromagnetic waves to communicate and enable non-contact information exchange.Compared with traditional two-dimensional code and bar code technology,RFID technology is more secure,flexible and automated.With the development of the mobile Internet of things,the passive EPC C1G2 standard has been well applied,but due to the ultra-low power consumption of related tags,traditional encryption technologies cannot be applied.The existing RFID system security protocols usually use the traditional Encryption algorithms,such as Hash,ECC,etc.However,since the lightweight EPC C1G2 standard RFID tags have fewer logic gates available and the tags themselves are passive,the related encryption algorithms are usually difficult to adapt to the tags based on the C1G2 standard,and therefore must be proposed.A security protocol that meets the features of the EPC C1G2 standard.Based on the summary of the existing lightweight RFID security protocols,this paper proposes a new lightweight RFID tag security protocol based on the EPC C1G2 standard,which integrates security certification and transfer of ownership rights.Participants of the agreement will further compose the security requirements of the IOT system,and will not need any interaction between the label and the label owner,nor will it need to store the information of the other party,which greatly reduces the storage burden of the label when the number of owners is large.In addition,the key of the tag is stored between itself and the server,and each round of the session key is automatically updated,which is more secure,and thus solves the problem that the existing protocol cannot transfer part of the ownership.This paper uses the theoretical analysis and the security of the GNY logic demonstration protocol.The experimental simulation is used to verify the correctness of the protocol.Compared with the existing protocol,this paper proves that this paper is not only feasible,but also more efficient in terms of power consumption.On the lower,more closely fit the actual needs of lightweight RFID systems.
