In public network, user authentication is important security technology. Especially, password-based authentication method is used the most widely in distributed environments, and there are many authentication methods. Their SPMA protocol indicates vulnerability about problem that NSPA protocol does not offer mutual authentication, and proposed Strong Password Mutual Authentication protocol with mutual authentication. However, SPMA protocol has vulnerability of replay attack. In the paper, we analyzed vulnerability to replay attack of SPMA protocol. And we also proposed Improved Strong Password Mutual Authentication protocol to secure on replay attack with same efficiency.

There are many investigations about the security on RFID system to protect privacy. It is important to mutual authentication of the security on RFID system. The protocol for mutual authentication use light-weight operation such as XOR operation, hash function and re-encryption. However, the protocol for authentication and privacy is required more complicated cryptography system. In this paper, we propose a mutual authentication protocol using finite field GF($2^n$) for a authentication and are a safety analysis about various attacks.

Ubiquitous sensor network is to manage and collect information autonomously by communicating user around device. Security requirements in Ubiquitous based on sensor network are as follows: a location of sensor, a restriction of performance by low electric power, communication by broadcasting, etc. We propose new mutual authentication protocol using a low power of sensor node. This protocol solved a low power problem by reducing calculation overload of sensor node using two steps, RM(Register Manager) and AM(Authentication Manager). Many operations performing the sensor node itself have a big overload in low power node. Our protocol reduces the operation number from sensor node. Also it is mutual authentication protocol in Ubiquitous network, which satisfies mutual authentication, session key establishment, user and device authentication, MITM attack, confidentiality, integrity, and is safe the security enemy with solving low electric power problem.

This paper demonstrates that an attacker can impersonate a random RFID tag and then perform the spoofing attack in the previous RFID authentication protocol. To resolve such a security problem, we also propose a new secure and efficient RFID mutual authentication protocol. The proposed RFID mutual authentication protocol is not only to resolve many security problems with the existing RFID authentication mechanism and the vulnerability against spoofing attack, but also to guarantee reliable authentication time as reducing computational overhead performing by tag. As a result, the proposed RFID mutual authentication protocol provides stronger security including the forward secrecy and more efficiency.

Authentication is one of the necessary elements in the network environment. Many researches have detected security vulnerabilities to the existing authentication mechanisms and suggested secure mutual authentication protocols by resolving these vulnerabilities. The representative ones of them are SPMA(Strong Pass Mutual Authentication) and I-SPMA(Improved Strong Password Mutual Authentication). However, these protocols cause a critical problem when the shared secret information is de-synchronized between the server and the client. This paper proposes a revised protocol to resolve the de-synchronization problem. Based on a security assessment on the proposed protocol, we consider the proposed protocol is safer than the previous ones and possible to effectively make a user authentication system mre secure.

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.

In the virtual home environment (VHE), which was proposed to offer global roaming and personal service environment portability, user's profiles and service logics are conveyed from home network to visited network to provide services at the visited network. Because user's profiles and service logics may contain confidential information, some procedures for mutual authentication among entities for offering confidence are needed. For these issues, we propose and analyze three 3-Party mutual authentication Protocols adaptable to the VHE in 3G ; password based mutual authentication protocol, mutual authentication protocol with CHAP and key exchange and mutual authentication protocol with trusted third party.

In this paper, we propose a lightweight mutual authentication protocol for secure and efficient home network service. Lee et al. recently proposed an attribute-base authentication key agreement protocol using public key in home network. Its protocol provided forward secrecy but don't diminish conspicious overhead of operation using ticket. Therefore the proposed protocol provided the security and efficiency using hash function and counter. Also it can provide secure home network service by check consumer electronics control level of users after created session key.

Authentication is an important service in wireless sensor networks (WSNs) for an unattended environment. Recently, Das proposed a hash-based authentication protocol for WSNs, which provides more security against the masquerade, stolen-verifier, replay, and guessing attacks and avoids the threat which comes with having many logged-in users with the same login-id. In this paper, we point out one security weakness of Das' protocol in mutual authentication for WSN's preservation between users, gateway-node, and sensor nodes. To remedy the problem, this paper provides a secrecy improvement over Das' protocol to ensure that a legal user can exercise a WSN in an insecure environment. Furthermore, by presenting the comparisons of security, computation and communication costs, and performances with the related protocols, the proposed protocol is shown to be suitable for higher security WSNs.

In 2006, Lee and Ahn proposed a matrix-based RFID authentication protocol which eliminates the security problems in HB and $HB^+$ 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.
