RFID system is the contact-less recognition technology and use for distribution system, environment, transport, security and so on. However, it may create many security relevant problems such as privacy because constraints of RFID communication environment. So several methods of resolving these problems have been proposed. Recently, Shin and Park proposed an efficient RFID authentication protocol with protecting user's privacy using hash function and exclusive-OR.. But Ahn and Bu et al. poia problem that a attacker can to masquerade as malicious reader because their protocol can't providing mutual authentication.nted out weakness of Shin and Park's protocol and proposed more secure and efficient protocol. Unfortunately, Ahn and But's protocol has In this paper, We propose an improved RFID authentication protocol providing mutual authentication. The proposed protocol has advantages that providing mutual authentication between a tag and a reader, secure against replay attack and spoofing attack. Also, it guarantees anonymity of RFID tag and secure against location tracking attack by collusion of malicious readers.

In a smart grid environment, data for the usage and control of power are transmitted over an Internet protocol (IP)-based network. This data contains very sensitive information about the user or energy service provider (ESP); hence, measures must be taken to prevent data manipulation. Mutual authentication between devices, which can prevent impersonation attacks by verifying the counterpart's identity, is a necessary process for secure communication. However, it is difficult to apply existing signature-based authentication in a smart grid system because smart meters, a component of such systems, are resource-constrained devices. In this paper, we consider a smart meter and propose an efficient mutual authentication protocol. The proposed protocol uses a matrix-based homomorphic hash that can decrease the amount of computations in a smart meter. To prove this, we analyze the protocol's security and performance.

RFID system is emerging new technology for ubiquitous computing environment. RFID system, however, provides privacy problems while the technology offers incredible rich opportunities for applications in the filed of logistics, distribution, and medical services, etc. Many researches have been conducted in order to solve this problem, but the current RFID authentication protocols are still insufficient for settling the privacy problem in the point of view of privacy intrusion and system efficiency. The purpose of this paper is to present a RFID mutual authentication protocol which improves safety level, compared with current authentication protocols. The proposed authentication protocol can provide mutual authentication services, and is secure against location tracing, spoofing, reflection attack.

As a new type of wireless network, Ad hoc network does not depend on any pre-founded infrastructure, and it has no centralized control unit. The computation and transmission capability of each node are limited. In this paper, a self-updating one-time password mutual authentication protocol for Ad hoc network is proposed. The most significant feature is that a hash chain can update by itself smoothly and securely through capturing the secure bit of the tip. The updating process does not need any additional protocol or re-initialization process and can be continued indefinitely to give rise to an infinite length hash chain, that is, the times of authentication is unlimited without reconstructing a new hash chain. Besides, two random variable are added into the messages interacted during the mutual authentication, enabling the protocol to resist man-in-the-middle attack. Also, the user's identity information is introduced into the seed of hash chain, so the scheme achieves anonymity and traceability at the same time.

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.

Now a days, as increased the use of mobile units like a laptop computer and PDA, the demand for high speed internet service is increasing. On the other hand, PKMv2 which is provided from IEEE 802.16e cannot support fully on the security of high speed internet service. This paper proposes light-weight mutual authentication protocol which solved security problem of PKMv2 related to integrity of mobile node for transmission of safe high speed data of mobile node operating in mobile WiMAX environment. Proposed mutual authentication protocol increases the efficiency as the user in network can move in network safely without additional procedure of authentication between subscriber and base station after user's initial authentication. Also, the proposed mutual authentication protocol is safe from the security attack (the man-in-the-middle attack and reply attack) between subscriber and base station by generating a key adopt to PRF() function using random number and secret value in order to secure certification.

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.

In this paper, we analyze the security vulnerability through the several attack scenarios for the MCR-MAP(Multi-Context RFID Mutual Authentication Protocol) proposed by Ahn et al. And we propose the secure mutual authentication protocol that improved a prior MCR-MAP. The suggested protocol uses the ID of the legal tag and the timestamp generated by the server, when the tag tries to authenticate. And when the tag creates the credential, we create the new secret key computing the XOR operation between the secret key shared with the server and the tag timestamp generated by the server. As a result, the proposed protocol provides the secure mutual authentication and then is safe to spoofing attack. Also it provides forward-secrecy and then is safe to offline brute-burst attack. In this paper, we compare and verify the security vulnerability of the prior and the proposed protocol through the security analysis.

In this paper, we propose a stable mutual authentication protocol between unmanned combat systems in tactical wireless networks where long distance communications are not always guaranteed due to a poor channel condition. The proposed protocol generates an authentication code using hash collision of arbitrarily selected random data. The authentication requester encrypts and transmits it to the authenticator. They performs authentication by sharing the valid authentication code. We analyze the safety of the proposed method for various attack scenarios.

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.
