  • E-authentication is one of the key functions for electronic transactions with the identification function made through the information systems. With the abolition of the mandatory use of public certificates, various private e-authentication services have emerged, and are developing to provide various additional services in addition to e-authentication. In this study, we explored the factors that affect user satisfaction with e-authentication services, compared the relative influence among the factors that we explored, and produced implications that could contribute to strengthening the competitiveness of e-authentication services. Based on the characteristics of e-authentication service, we searched and found four factors such as availability, convenience, added functionality and security. After that, we established and analyzed our research model to analyze the causal relationship between these four factors and user satisfaction. The analysis results showed that availability, convenience and security had significant effects on user satisfaction, but added functionality had no significant impact. In addition, compared to availability and convenience, security had a very strong impact on user satisfaction. This study suggests that e-authentication service providers should make efforts to make users aware of the usefulness of additional services while enhancing security.

  • In this Paper, we present a novel authentication and key exchange(AKE) protocol for inter-NSP(provider) roaming in IEEE 802.16e networks. The proposed protocol allows performing both user and device authentication jointly by using two different authentication credentials and Provides user anonymity and session key establishment. Also, this protocol requires only two round number message exchange between foreign network and home network.

  • EAP (Extensible Authentication Protocol) is often used as an authentication framework for two-party protocol which supports multiple authentication algorithms known as "EAP method". And PKMv2 in 802.16e networks use EAP as an authentication protocol. However, this framework is not efficient when the EAP peer executing handover. The reason is that the EAP peer and EAP server should re-run EAP method each time so that they authenticate each other for secure handover. This makes some delays, so faster re-authentication method is needed. In this paper, we propose a new design of the PKMv2 framework which provides fast re-authentication. This new framework and usage of the keys which used as a short-term credential bring better performance during handover process.

  • e-Passport system is new type of emigration and immigration control system and it is a research to introduce the e-Passport Authentication Protocol with Improved Efficiency is lively proceeded over the entire world. The e-Passport's chip has a biometric information and personal identification information, Radio Frequency Identification(RFID) technology is used for communication with the Inspection System(IS). However, the feature of the RFID system may bring about various security threats such as eavesdropping, data forgeries, data alternation, cloning, biometric data-leakage. Therefore, in this paper, we analyse the e-Passport system's authentication protocol to protect vulnerability and proposed e-Passport system's authentication protocol reduce computation. Also, we compared their efficiency.

  • This paper reinforced security under the network evaluation of wire wireless integration of NEMO (NEwork MObility) supporting mobility and network-based PMIPv6 (Proxy Mobile IPv6). It also proposes $SK-L^2AS$ (Symmetric Key-Based Local-Lighted Authentication Scheme) based on simple key which reduces code calculation and authentication delay costs. Moreover, fast handover technique was also adopted to reduce handover delay time in PMIPv6 and X-FPMIPv6 (eXtension of Fast Handover for PMIPv6) was used to support global mobility. In addition, AX-FPMIPv6 (Authentication eXtension of Fast Handover for PMIPv6) is proposed which integrated $SK-L^2AS$ and X-FPMIPv6 by applying Piggybacks method to reduce the overhead of authentication and signaling. The AX-FPMIPv6 technique suggested in this paper shows that this technique is better than the existing schemes in authentication and handover delay according to the performance analysis.

  • In WSN environment, the sensor nodes collect sensed data, and transmit data to the BS. BS is difficult to trust the data from unauthenticated nodes. Therefore, many papers have been proposed about the node authentication and the safety of data. In the AM-E paper, data is delivered after node authentication. In this time, the sensor nodes are directly communicated to BS the AREQ/AREP message for authentication. Therefore, the sensor nodes consume more energy for authentication. Also, noes communicate directly with the BS for authentication will have problem due to the limited energy of nodes. In this paper, the same security with AM-E is supported, Furthermore, to minimize the energy consumption, IDE based hierarchical node authentication protocol is proposed. Compared with AM-E, the number of alive nodes is increased about 39%. Thus, the entire network life time is extended and energy efficiency is improved.

  • If protocol has fast operations and short key length, it can be efficient user authentication protocol. Lenstra and Verheul proposed XTR. XTR have short key length and fast computing speed. Therefore, this can be used usefully in complex arithmetic. In this paper, to design efficient user authentication protocol we used a subgroup of Galois Field to problem domain. Proposed protocol does not use GF(p/sup 6/) that is existent finite field, and uses GF(p²) that is subgroup and solves problem. XTR-ElGamal based user authentication protocol reduced bit number that is required when exchange key by doing with upside. Also, proposed protocol provided easy calculation and execution by reducing required overhead when calculate. In this paper, we designed authentication protocol with y/sub i/ = g/sup b.p/sup 2(i-1)//ㆍv mol q, 1(equation omitted) 3 that is required to do user authentication.

  • Authentication and key establishment are fundamental procedures to establish secure communications over public insecure network. A password-based scheme is common method to provide authentication. In 2008, Khan proposed an efficient password-based authentication scheme using smart cards to solve the problems inherent in Wu-Chieu's authentication scheme. As for security, Khan claimed that his scheme is secure and provides mutual authentication between legal users and a remote server. In this paper, we demonstrate Khan's scheme to be vulnerable to various attacks, i. e., password guessing attack, insider attack, reflection attack and forgery attack. Our study shows that Khan's scheme does not provide mutual authentication and is insecure for practical applications. This paper proposes an improved scheme to overcome these problems and to preserve user anonymity that is an issue in e-commerce applications.

  • The accurate user- authentication technology is being raised as one of the most important in this current society, which is, so called, information society. Most authentication technology is used to identify users by using the special characteristics of users. This paper has established an e-commerce shopping mall based on conventional e-commerce systems. It also suggested and established the user authentication interface that uses the mouse gesture, which is the new authentication of what users have. The user authentication interface using the mouse gesture generates the status of recognition directly on the screen by comparing the stored pattern values with the unique pattern values that users entered. When users purchase products through the shopping mall and enter their another signature information together with payment information, security can be more increased. Experimental results show that our mouse gesture interface may be useful to provide more security to e-commerce server.

  • An e-Seal is an active RFID device that was set on the door of a container. e-Seal provides both the state of the seal and the remote control of the device automatically. But it has vulnerabilities like eavesdrop and impersonate because of using RFID system. A secure e-Seal authentication protocol must use PRF for encryption/decryption of reader and e-Seal. The existing PRF uses simple hash function such as MD5 or SHA which is not available for e-Seal. It is required to use strong hash functions. The hash function is a essential technique used for data integrity, message authentication and encryption in the mechanism of information security. Therefore, in this paper, we propose more secure and effective hash function based on polynomial for e-Seal authentication protocol.
