In 2010, Jeon-Kim proposed HMAP(Hash-based Mutual Authentication Protocol for RFID Environment) to resolve a variety of problem related to security using Mutual authentication scheme, the hash function and secret key is used to update in RFID system. Jeon-Kim proved RMAP was safe for a variety of attacks including eavesdropping attacks through safety analysis. However, unlike the claims of the proposed protocol is vulnerable to next session of the secret key exposure due to eavesdropping. In this paper, we analyze the problem of RMAP and proves it through security analysis. And we also propose improved an RFID Mutual Authentication Protocol based on Hash Function to solve problems of HMAP.

Recently, research on security of RFID system has been conducted actively in order to utilize RFID system in various fields including distribution and logistics. This paper suggests an authentication protocol which supplement the flaws of previous RFID authentication protocols and we improved its performance using matrix-based authentication. The suggested authentication protocol provides mutual authentication, protects from wiretapping attack, replay attack, spoofing attack, and traffic analysis attack and so on, and reduces overload of back-end database so that has efficient performance.

Recently RFID system is used in various fields such as distribution industry, medical industry and military service. The technology for protecting individual privacy is necessary to adapt RFID system in several applications. This paper proposes an authentication protocol which conducts mutual authentication between back-end database and tag using hash function. The proposed protocol satisfies various RFID security requirements : mutual authentication, anonymity, confidentiality, integrity, replay attack, location trace. This protocol reduces the time for authentication minimizing the number of hash operation in back-end database.

Mobile RFID system, that consists of the existing RFID reader mounted on the mobile devices such as smartphones, is able to provide the users a variety of services and convenience. But security of mobile RFID system is too weak like the existing RFID system. In this paper, the mobile RFID mutual authentication protocol with high level of security is proposed to overcome the troubles such as cryptographic protocols in the existing RFID system responding with the same value in every authentication procedure and the exposure in the exchange of messages. The proposed protocol exchanges messages unexposed by using the random numbers generated in the mutual authentication between the tag and the reader and making numbers coded with the symmetric key. Besides, the protocol uses the mutual authentication utilizing OTP by considering the characteristics of the reader embedded in mobile devices in the mutual authentication process between the reader and the server. Because changed message in every authentication, which produces safe from spoofing attacks and replay attacks, etc.

The RFID system is very useful in various fields such as the distribution industry and the management of the material, etc. However, the RFID system suffers from various attacks since it does not have a complete authentication protocol. Therefore, this paper propose the authentication protocol that used key server to resist various attacks including DoS(Denial of Service) attack. For easy implementation, the proposed protocol also uses CRC, RN16 generation function existing in EPCglobal class 1 gen2 protocol. This paper performed security analysis to prove that the proposed protocol is resistant to various attacks. The analytical results showed that the proposed protocol offered a secure RFID system.

This paper proposes an authentication protocol based on hash and AES safe from various types of attacks in order to assure the security of communication between tags and readers, which exchange data with each other wirelessly in a RFID system. The proposed authentication protocol resolves a problem in existing hash-based protocols whereby the same hidden value is generated for the same identification in each session. In order to hide tag identification information a number of complicated calculations were required, but using the proposed AES protocol reduces such calculations, strengthens security against replay attack, spoofing attack, traffic analysis, eavesdropping, etc. and assure mutual authentication between tags and readers.

RFID system is used in several fields such as traffic and access control. The study about RFID security is actively progressed as security threat has been increased. This paper suggests matrix-based authentication protocol. And we analyze the safety of authentication protocol and compares the effectiveness of the protocol with other authentication protocols. The suggested authentication protocol secures from wiretapping attack, replay attack, and spoofing attack, and reduces overload of back-end database so that has efficient performance.

This paper proposes an authentication protocol using the key server in the ECPglobai RFID system. The proposed authentication protocol uses the key server and the time-out mechanism to resist various attacks including DoS(Denial of Service) attack. For easy implementation, the proposed protocol also uses the function existing in EPCglobal class 1 gen2 protocol without additive function such as hash function. The proposed protocol is evaluated through two analytical methods. The correctness of the proposed protocol is proved using the GNY analysis. By the security analysis, this paper showed that the proposed protocol is resistant to various attacks including DoS attack. The analytical results demonstrated that the proposed protocol offered a secure RFID system.

In 2008, Kim-Jun proposed a RFID mutual authentication protocol using one-time random number that can withstand malicious attacks by the leakage of important information and resolve the criminal abuse problems. Through the security analysis, they claimed that the proposed protocol can withstand various security attacks including the replay attack. However, this paper demonstrates that Kim-Jun' s RFID authentication protocol still insecure to the replay attack. In addition, this paper also proposes a simply improved RFID mutual authentication protocol using one-time random number which not only provides same computational efficiency, but also withstands the replay attack.

Recently, Ahn et al proposed an improved authentication protocol using the hash function in RFID environment. Their proposed protocol provide the following three merits; it reduces the computational costs of RFID tag. itrfduces the communication overhead between the reader and the tag. it protects the user privacy. However, this paper points out that does not authenticate the legality of the RFID reader and database. this paper proposes an improved mutual authentication protocol that can provide the mutual authenticaion.
