Future Internet has been designing and developing in the world because of overcoming limits of current Internet and accepting new requirements. Therefore it is totally different from architectures of current Internet and it is based on Clean-Slate. Future Internet already has been studying with enormous investment by advanced countries such as USA, EU etc. Technical characteristics of Future Internet can be categorized into Infra techniques, Architectures and Service techniques. Especially, our country is in a superior position in Infra techniques and Service techniques. We can have competitiveness to develop trust communication in Future Internet because we have advantages of various Services such as mobile communication, Machine to Machine and Sensor Networks. This paper aims to analysis reference model of trust communication in Future Internet. To achieve this, we studied analysis of security techniques in four Future Internet researches of NSF.

Recently, the increased use of anti-ship guided missiles, a weapon system that detects and attacks targets in naval engagement, has come to pose a major threat to the survivability of ships. In order to improve the survivability of ships in response to such anti-ship guided missiles, many studies of means to counteract them have been conducted in militarily advanced countries. The integrated survivability of a ship can be largely divided into susceptibility, vulnerability, and recoverability, and is expressed as the conditional probability, if the ship is hit, of damage and recovery. However, as research on susceptibility is a major military secret of each country, access to it is very limited and there are few publicly available data. Therefore, in this study, a possibility of estimating the susceptibility of ships using an anti-air defense system corresponding to anti-ship guided missiles was reviewed. To this, scenarios during engagement, weapon systems mounted to counter threats, and maximum detection/battle range according to the operational situation of the defense weapon system were defined. In addition, the effectiveness of the anti-air defense system and susceptibility was calculated based on the performance of the weapon system, the crew's ability to operate the weapon system, and the detection probability of the detection/defense system. To evaluate the susceptibility estimation feasibility, the sensitivity of the detailed variables was reviewed, and the usefulness of the established process was confirmed through sensitivity analysis.

The present study numerically analyzed the dynamic behavior of 3D framed structures subject to impulsive slamming forces by violent breaking waves. The structures were modeled using multiple lumped masses for the vertical projections of each member, and the slamming forces from the breaking waves were concentrated on these lumped masses. A numerical algorithm was developed to properly incorporate the slamming forces into a dynamic analysis to numerically determine the structural responses. Then, the validity of the numerical analysis was verified using the results of an existing hydraulic experiment. The numerical and experimental results for various model structures were generally in good agreement. The uncertainties concerning the properties of the breaking waves used in the verification are also discussed here.

A scale model test for ship Infra-Red signature measurements at sea is impossible, because it is sensitive to the environment. Since we can't control the meteorological environment of the real sea, it can't be carried out with the desired maritime environments. Therefore, in the sea, we made measurements of the weather, operating conditions of the ship, and ship IR signatures under given conditions, and then analyzed them. Conversely, we compared the results of the test with a prediction for a given scenario condition. This paper describes the test items, procedures, and measuring instruments of the experiments at sea and the results from basic researches for methods of estimation and analysis of the measured data.

To develop in the long view, based on context of city, the spatial program change to new spatial program that can be adopt city architectural environment. The new spatial program must have paring lot, open space, community center, which are infra structure for citizen. The needs about flexible space Increase according to complexity of spatial program. The space of absolutism, is made up hierarchy, can't accommodate complexity of spatial program. Therefore, modern architectural spaces are characterized by non-hierarchy. This research is tendency to search special quality of space program that is going complex composition according to change of modern society and modern architecture space, and analyze characteristic of inner space that have non-hierarchy to correspond hereupon.

In these days, our social infra which are computer and internet has been developed and our community has been digitalized with a large quantity information that can be sharable or productive. So we can say that older knowledge organization based on the man power is changing with automatical and intellectual aspect. Thus we have to apply this movement to get the high efficiency and the competitive power in the organization and to take the voluntaries attitude of operator with real time inputting or fast calculating speed. Beside most of developed countries are owned their power system analysis software. Like kind of this facts can affect for national reliance. So in this paper we propose that the suggestion for both field power system and IT how these can be cooperated. The note that this paper is came from the project which name is Graphics Power Flow analysis.

Data security is an important issue in today's computer networks. In order to construct a safe infra in the open communication network, a cryptography is necessarily applied to several communication application fields like a high-speed networking system supporting real-time operation. A cryptography which has already realized by a software is designed by using a hardware to improve a throughput. In this paper, we design hardware architecture of IDEA by using a single iterative round method to improve a encryption throughput. In addition, we intend to develop a hardware design methodology that a specific cryptography operate with high-speed. The hardware model is described in VHDL and synthesized by the Samsung KG 80 Library in the Synopsys development software tool. With a system clock frequency 20MHz, this hardware permits a data conversion rate of more than 116 Mbit/s.

The threat to the network is increasing due to explosive increasing use of the Internet. Current IDS(Intrusion Detection System) detects intrusion and does individual response in small area network. It is important that construction of infra to do response in all system environment through sharing information between different network domains. This paper provides a policy-based IDS management architecture enabling management of intrusion detection systems. The IIDS(Integrated Intrusion Detection System) is composed of IDAs(Intrusion Detection Agents). We describe requirements in design and the elements of function.

그동안 많은 솔루션 벤더들이 다양한 이기종 시스템들의 느슨한 연결 및 유연한 서비스 중개, 용이한 확장성까지 두루 갖춘 통합된 비즈니스 지원플랫폼 모델을 제시해 왔다. 최근 표준 웹서비스 기술과 SOA(Service Oriented Architecture) 개념이 확산되면서, 이를 ASP비즈니스의 서비스 어플리케이션 통합 및 비즈니스 프로세스 통합에 적용하는 사례도 증가하고 있다. KT는 현재 상용서비스 중인 ASP비즈니스 'bizmeka' 의 현황을 분석하고, 시장을 예측하여 다양한 경우의 비즈니스 프로세스들을 모듈화 및 웹서비스화한 후, 이를 메시지 라우팅 및 워크플로우 기능을 통해 실행하는 구조의 SOA 기반 ASP비즈니스 지원플랫폼을 개발하고 있다. 본 논문에서는 ASP비즈니스 지원플랫폼 구축의 기반 기술로서 SOA 및 관련 기술에 대해 살펴보고, KT가 개발 중인 플랫폼의 개념과 모델, 설계 및 구현 내용 등을 소개한다.
