A Secure Authentication Protocol for Cloud Services

The request about green IT technology is increasing recently. And effective use request of computer resource is increasing. So, necessity about Cloud computing is increasing rapidly thereby. However, Cloud computing environment have big security problems because embody using virtualization technology. It is Authentication that must solve in Cloud computing environment urgently. Therefore, we wishes to propose protocol that can solve suitable user and services certification in cloud computing environment. An novel authentication protocol that based on Kerberos. But it is faster than Kerberos and implement is easy.

A System of Authentication and Security threat solution for N-screen services

Abstract N-screen is a Service that can be provide for One Service Multi Device. If the network is changed or if the device is changed after authentication the device fits seamlessly send footage. Security threats that occur here have a problem with user authentication. In this paper proposes available in a multi-device the authentication system. Homomorphic Encryption Algorithm of authentication scheme used. Among the authentication mechanism that already exists is a simple and lightweight authentication mechanism. In addition, N-screen service that uses multiple devices is simple authentication process of the device. Review the results of proposed authentication protocol, encryption algorithm to process a small storage capacity and is easy to work in low processor. And was suitable for use with multiple devices.

An Efficient BRS Management System Using OAuth

Trend of information is diversified fast by the spread of wireless internet recently. The service of book information search may be available without limitation of time and place in university library, because fast diffusion of electronic publishing is increasing. Therefore, we wishes to propose the convenience to search another college’s digital property or display by printer simplifying certification between majority college that is using OAuth. We can propose case and certification formality of the library which is not conferred mutually that is conferred mutually and share island and media search effectively cloud computing and Mobile communication environment.

Research of Virtualization Services Valuation for Cloud Computing Environments

Demand of cloud computing service that uses the Big-table is increasing recently. This is effective method to use computer resource to user ubiquitously. So, Internet Service and Virtualization Service are must be prepared to offer Cloud Computing Environments. In this time, virtualization service infrastructure has independent structure that is offered by each companies design and created specifications, Because of standardization about function, specification and performance are unprepared state about virtualization services. Therefore, we wish to propose common standards that can measure standard functions and performance of virtualization service, which can apply to companies which provide service. We established 6 common estimation items with functionality, authoritativeness, usability, efficiency, preservation conservativeness and portability about virtualization solutions. And about each item, established suitable 19 detail estimation items to ISO/IEC 9126 concretely. We examined whether we observe 19 details estimation items that the most representative VMware solution proposes among virtualization solutions. And we described results that examine availability whether we are suitable standard function and service about existent virtualization service using our proposed scheme in this research.

Approach of Tracing Prevention System Using OAuth for Printing Services in Mobile Device

The smart phone user is increasing very sharply. Smart phone user passes over 30 million people at 2012 in domestic. And Social Network Service user is expecting to come in about one billion people in worldwide. And smart phone used at most Android operation system. This has advantage that can offer freedom to move and convenience to user. But, most smart phone has various kind controversial points to security. Specially, we are interested about authentication and user position tracing problem among various kind security problems that occurrence is possible in smart phone using environment. And we want to suggest solving these problems. Therefore, we wish to propose that can check certification and position chase problem using OAuth to happen in smart phone expected position chase problem system. To example, we presented case that make use of printer that is shared in the nearest position with own because user uses smart phone. In case, we thought that our proposal system can solve tracing problem and various additional security problems such as confidentiality, integrity, and access control etc.
