A low-cost, efficient and safe mutual authentication protocol for RFID based on elliptic curve cryptography (ECC) is proposed, specific to the security and privacy problem existed in the existing RFID authentication protocol, on the basis of deep analysis of the existing RFID protocol based on ECC.As to this proposal, mutual authentication between the tag and reader can be realized only through two sessions, under the condition of not destroying the security strength.So, the workload of calculation and system resource expense are reduced.The paper has described the protocol in detail and analyzed its security.The analysis result shows that, the protocol can resist tracking attack, replay attack, man-in-themiddle attack and other attacks, has good forward security and can realize mutual authentication between the server and the tag.Besides, it has definite practicability, due to low cost, security and scalability.
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 2006, Lee and Ahn proposed a matrix-based RFID authentication protocol which eliminates the security problems in HB and RFID authentication protocols. Their proposed protocol provides the following three merits: (1) it reduces the computational costs of the RFID tag. (2) it reduces the communication overhead between the reader and the tag. (3) it protects the user privacy. However, this paper points out that Lee and Ahn's proposed protocol is insecure to various attacks because it does not provide mutual authentication which the RFID tag does not authenticate the legality of the RFID reader unlike their claims. In addition, this paper proposes an improved matrix-based RFID mutual authentication protocol that can provide the mutual authentication. As a result, the proposed protocol not only can provide strong security and but also guarantee high efficiency because it reduces the communication rounds compare with Lee-Ahn's protocol.
RFID security protocol is one of the most important ways to solve security problems of RFID system and it is the focus of current research. This article summarized and classified the common security protocols, then proposed a new mutual authentication protocol without the back-end database which aimed at the actual need of military applications and proved the correctness of the new protocol by GNY logic. Safety analysis shows that the new protocol can effectively protect privacy, prevent tracking and avoid synchronization attack and such common problems. The protocol has not only high security, but also the obvious advantage of flexibility.
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.
Radio frequency identification (RFID) is one of the key technologies which constitute internet of things. Security and privacy issues of RFID systems is the focus of the present study. By analyzing several typical RFID security protocols, for the special security requirements of RFID systems in internet of things, in the paper, we propose a communication protocol SPAP(security-provable authentication protocol), then analyze and demonstrate the security of the protocol in details by the random oracle model. Analysis show that the protocol not only can solve the tag tracking, replay attack, cloning attack and the tag information indistinguishable, but also can solve the internal attack and the ownership transfer of tags and other issues of RFID Systems in internet of things. Finally, according to the comparisons, SPAP has the best performance.
