In 2008, Kim-Jun proposed RFID Mutual Authentication Protocol based on One-Time Random Numbers which are strong in Eavesdropping Attack, Spoofing attack and Replay attack. However, In 2009, Yoon-Yoo proved that it was weak in Replay attack and proposed a protocol which can prevent Replay attack. But Yoon-Yoo's protocol has problems that efficiency on communication and Brute-force attack. This paper shows weak points of Yoon-Yoo's protocol and proposes an RFID mutual authentication protocol with security and performance improvements.

RFID security protocol is widely discussed as an important issue, while the mutual authentication with the security agreement is mostly discussed enthusiastically. In this paper we improve HB family to achieve the property of mutual authentication, so that the user privacy can be protected. The future direction is to adapt the protocol for cloud computing.

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.

In this paper, we proposed a new secure RFID(Radio Frequency IDentification) mutual authentication protocol on insecure communication channel which assumed that all communication channels between the database, the reader and the tag are insecure communication channels. The proposed protocol used a secure one-way hash function and the goal is to improve search time of a tag ID and overload of hash calculational load in DB. In addition, the proposed protocol supports not only basic security requirements to be provided by RFID mutual authentication protocol but also forward secrecy, and the tag does not generate a random number to reduce overload of processing capacity in it.

Recently many mutual authentication protocol for light-weight hash-based for RFID have been proposed. Most of them have assumed that communications between a backend server and reader are secure, and not considered threats for backend server and RFID reader impersonation. In the real world, however, attacks against database or reader are more effective rather than attacks against RFID tag, at least from attacker's perspective. In this paper, we assume that all communications are not secure to attackers except the physical attack, and considering realistic threats for designing a mutual authentication protocol based on hash function. And It supports a mutual authentication and can protect against the replay attack, impersonation attack, location tracking attack, and denial of service attack in the related work. We besides provide a secure and efficient RFID mutual authentication protocol which resists impersonation attacks on all of the entities and alow a backend server to search tag-related information efficiently. We conclude with analyzing the safety and efficiency among latest works.

RFID system is a technique to obtain information of tag using radio frequency. Specificity of RFID systems using radio frequency has many problems that is eavesdropping, location tracking, spoofing attack, replay attack, denial of service attack. So, RFID protocol should be used cryptographic methods and mutual authentication for security and privacy. In this paper, we explain the problem of past protocol and propose the nonfixed symmetric key-based RFID mutual authentication protocol using shift computation and random number. Proposed protocol is secure from various attacks. Because it use shift operation and non-fixed symmetric key.

Tags and Readers is receiving and sending the data using the wireless communication in the RFID environment. Therefore, it could allow an attacker to participate in the network without the physical constraints, which can be easily exposed to a variety of attacks, such as taps and data forgery. Also, it is not easy to apply the security techniques to defend external attacks because the resource constraints of RFID tags is high. In this paper, new tag-reader mutual authentication protocol is proposed to protect the external cyber attacks such as spoofing attacks, replay attacks, traffic analysis attacks, location tracking attacks. The performance evaluation of the proposed mutual authentication protocol is performed and the simulation results are presented.

General RFID system has assumed that the communication channel between reader and back-end database is secure channel. However, the reader can be communicated with the database through insecure channel like the communication channel between the reader and the tag according to application environment. In this paper, we propose a new secure RFID mutual authentication protocol based on open network channel which assumed that all communication channels between the database, the reader and the tag are insecure communication channels. The proposed protocol uses a secure one-way hash function to provide authentication and integrity against all communication messages which exchanged on the open channels. In addition, we designed that the proposed protocol can provide forward secrecy by performing the database and the tag update their old secret key with a new secret key after finished mutual authentication.

Recently use of RFID(Radio Frequency Identification) tends to be rapidly increased and will be also extended throughout the whole life. Using radio-frequency data can be recognized automatically in the RFID system is vulnerable to personal information protection or security. And passive tags have a hardware problem is the limit for applying cryptographic. This paper presents an authentication protocol using AES and Nounce. After completing mutual authentication server to access and strengthen security vulnerability to the use of the Nounce, because safety in denial of service attacks.

In this paper, we have proposed a secure dynamic ID allocation protocol using mutual authentication on the RFID tag. Currently, there are many security protocols focused on the low-price RFID tag. The conventional low-price tags have limitation of computing power and rewritability of memory. The proposed secure dynamic ID allocation protocol targets to the high-performance RFID tags which have more powerful performance than conventional low-price tag by allocating a dynamic ID to RFID using mutual authentication based on symmetric encryption algorithm. This protocol can be used as a partial solution for ID tracing and forgery.
