The Design And Analysis Of RFID Group Authentication Protocol

So far,about the research of RFID(radio frequency identification)group authentication protocol is still in the exploratory stage.Although quit e a few RFID group authentication protocols have been proposed,many existing protocols have some security vulnerabilities and privacy proble ms to be solved.In addition,most of the protocols lack of strict formalization analysis and proof.RFID group authentication security model is hereby proposed,and on this basis a kind of safe and efficient RFID group authentication protocol is designed.Firstly,existing security vulnerabilities and privacy problems in existing relevant protocols are analyzed from the perspective of attackers.For example,the familiar replay attack,interleaving attack and privacy leakage.After highly abstracting concept or method by using formalization method,using specific model to describe,RFID group authentication security model is proposed,and the security model is verified according to a specific protocol.An improved RFID group authentication protocol is proposed according to RFID group authentication security model,and the acceleration scheme of the protocol is proposed by using grouping ideology.Then,the formalization analysis and security proof aimed at the proposed RFID group authentication protocol are completed with the aid of the security model,and the protocol’s ability to protect privacy is analyzed.The proposed RFID group authentication security model could help implement formalization analysis and proof aimed at relevant protocols,and it has cer tain reference significance for RFID group authentication security protocol.In addition,the proposed RFID group authentication protocol can resist familiar attacks,and it possesses anonymity and untraceability.The proposed protocol possesses greater security and better privacy protection ability when compared to several other relevant protocols.Furthermore,the proposed RFID group authentication protocol acceleration scheme can multiply the execution efficiency.
