In order to content with the security requirements of RFID system,the study uses mathematic and cryptography methods to solve these problems.Considering the security,privacy and effectiveness of RFID protocol,the paper researches the authentication protocol of the RFID system and proposes a mutual authentication protocol of RFID.Its safety and performance analysis show that the proposed protocol is relatively good in these aspects.It can prevent many security including contents privacy,location tracing,replay attack,spoofing attack,and also has forward security ability.
In order to solve the weakness in security and privacy and the poor performance of the existing RFID authentication protocols,a Hash-based mutual authentication protocol for RFID is proposed and its security is proved by using the provable security model,with the privacy and security features of the proposed protocol analyzed.Compared with several RFID authentication protocols with the similar structure,the proposed protocol can effectively solve the privacy and security issues of the RFID system and has significant performance advantages,because it greatly reduces the amount of storage and computation of tags,and particularly improves the search efficiency of the server database.
With the advantage of long distance, high speed and low cost, the UHF RFID technology has become a hot research area of RFID and it will become a fundamental technology of future information society construction. Because of the openness of RFID, RFID application takes a risk of being attacked, security and privacy issues become a constraint bottleneck to its further development. To solve the existing problems of UHF RFID authentication protocol, the article proposed a reliable RFID authentication protocol. The new protocol solves many security problems including mutual authentication, anonymity, untraceability, anti-impersonation and anti-replay.
With the extensive application of Radio Frequency Identification(RFID),the contradiction between its security and computation is serious.On this background,the security defects and cost of the main RFID secure authentication protocols are analyzed.On this basis,a new authentication protocol is promoted with higher security and lower cost.Its security is verified via the strand space model,which proves that the mutual authentication of reader and tag can be realized safety and reliability.The analysis results show that the protocol is resistible to attacks such as spoofing attack,eavesdrop attack,replay attack,type flaw attack,tracking and so on,and also provides perfect forward secrecy,which has a lower computation,and is suitable for low-cost RFID system.
As for so many security vulnerabilities, such as readers' ID-disclosure attack, man-in-the-middle attack, spoofing attack in Yao's authentication protocol, we propose a Radio Frequency Identification mutual authentication protocol based on NTRU public key encryption system, and perform formal analysis with GNY logic. The protocol not only has character of once a secret, but also the session key exchanged when mutual authentication protocol completed.Main computing tasks is implemented on the readers, so the pressure of server can be reduced effectively, the position tracking and forward security issues exist in current protocols can be solved as well. Analytic result shows that the proposed mutual authentication protocol can resist replay attack, counterfeit attack, denial of service attacks and other malicious attacks,and has featuresof low computational complexity,little communication,high efficiency. It is suitable for apply this protocol in low-cost tags.
The Radio Frequency Identification(RFID) grouping-proof protocol is used to verify whether there are multiple tags,because in actual scenario,these tags are used for the identification of one object.However,due to the simple structure and limited computing and storage resources of the RFID tags,the security protocol is difficult to achieve.To address this problem,this paper proposes a grouping-proof protocol that insures privacy and forward security.First,this paper uses hash function and randomization to guarantee the confidentiality and privacy of each session.Then,by means of activate-sleep mechanism,filter-response mechanism and the combination of identity authentication and grouping-proof technology,the efficiency of protocol is improved.Analysis results show that the RFID grouping-proof protocol meets the requirements of anonymity and forward security,so it can prevent eavesdropping,tracking attack,replay attack and de-synchronize attack.
