AAA protocol is an information protection technology which systematically provides authentication, authorization and accounting function not only in the existing wire network but also in the rapidly developing wireless network, various services and protocol. Nowadays, standardization of the various application services is in progress with the purpose of AAA standardization fer the mobile user in the wireless network. And various researches are being conducted fur using AAA in the roaming service and mobile IPv6 network between heterogeneous networks. In this paper uses OTP and ID-based ticket for user authentication in the mobile device under the ubiquitous environment, and service is seamlessly provided even though the mobile device moves from the home network to the foreign network. In addition, with the ticket renewed from the foreign network, the overhead of the home authentication server can be reduced, and provides anonymity of service through the anonymity ID.

This paper aims to design and realize mobile webapp ticket reservation system based smartphone with N-tier mobile webapp framework. In mobile framework, presentation-tier utilizes HTML5/CSS3 and Sencha Touch, middle-tier consists of spring framework and MyBatis, database-tier using oracle possible to apply enterprise services mobile webbapp offices. In this study, mobile framework deploy and configuration management without the support of the app in N-tier that does not need to be considered in the smartphone-based mobile webapp ticket reservation system analysis and design, and then implementation.

The all-in-one service, for example, mobile wallet enables users to have credit card, membership card, and coupon in one place. It has been one of important o2o services with offline payment. In order to take advantage of mobile commerce, it is necessary to authenticate clients automatically without entering their passwords. This paper proposes an automatic client authentication method in all-in-one service. At registration, clients receives and stores an authentication ticket from a company, which contains an user's identifier and password encrypted by company's symmetric key. Client can be authenticated by transferring authentication tickets to companies at service requests.

AAA(Aluthentieation, Authorization, Accounting) protocol is an information securitv technology that offer secure and reliable user Authentication, Authorization, Accounting function systematically in various services. protocol and wireless network work as well as win network. Currently IETF(Internet Engineering Task Force) AAA Working Group deal with about AAA protocol and studying with activity, But, recently it exposing much problems side to user's anonymity and privacv violation. Therefore, in this paper, AAAH(Home Authentication Server) authenticaters Mobile device, after that, use ticket that is issued from AAAH even if move to outside network and can be serviced offering authentication in outside network without approaching by AAAH, Also, we study mechanism that can offer user's privacy and anonymousness to when use service. Our mechanism is using Time Synchronization OTP and focusing authentication and authorization. Therefore, our mechanism is secure from third party attack and offer secure and effective authentication scheme. Also only right user can offer services by using ticket. can reduce signal and reduce delay of message exchanged, can offer persistent service and beighten security and efficiency.

Recently, with rapid advances of mobile devices such as smart phone and wireless networking, a number of services using mobile device based wireless network have been explosively increasing. From the viewpoint of security, because wireless network is more vulnerable than wired network, strong security is required in wireless network. On the contrary, the security for mobile devices has to be efficient due to the restrictions of battery powered mobile device such as low computation, low memory space and high communication cost. Therefore, in this paper, we propose an efficient authentication scheme with mobile devices in wireless network environment. The proposed scheme satisfies security requirements for the service using mobile device and it is suitable in wireless network environment.

In this paper, we design an authentication model based mobile PKI (Public Key Infrastructure). The authentication mood consists of Root-CA Home-network agent and Foreign-network agent. CA will going to gave the delegation ticket to Home-Agent or Foreign-Agent when they request. The authentication mode information security is various characteristic more then high speed, mobile network and low cost more then previous structure of assure information security.

NFC is a Near Field wireless Communication technology, comes to the fore as an important technology of Mobile Payment System with supply of devices and diffusion of services. Because of the fact that the NFC retail payment services, ticketing, smart cards are able to operate in one device, it(NFC Technology) can make disclosure of personal information and security risks. Thus, the problem of security in NFC technology is essential, and the need for research on security threats are increasing. In this paper, we wil analyze for NFC's vulnerabilities and security technology.

In this paper, we propose the fast and secure binding update protocol as handoff or handover in the micro and pico environment based on mobile IPv6. The nodes or routers on participating in this protocol generate their addresses from cryptographically generated addresses (CGAs) method unlike previous address generation method. The mobile node (MN) includes in home network or home link has limited power and computational abilities. So the home agent (HA) of the MN executes key agreement protocol with the correspondent node (CN) on behalf of the MN. The CN then creates a ticket on including session key, lifetime of ticket. and so on. It then transmits it to the MN via the HA of the MN. The ticket is used to communicate directly between the MN and its CN. In performance analysis, we analyze security of proposed binding update protocol under various attack scenarios and efficiency by comparing proposed protocol with prior binding update protocols. Finally we make a conclusion of this paper and present future works.
