The evolution of IoT technology is having a significant impact on people's lives. Almost all areas of people's lives are benefiting from increased productivity and simplification made possible by this trending technology. On the downside, however, the application of IoT technology is posing some security challenges, among them, unauthorized access to IoT devices. This paper presents an Attribute-based Access Control Fog architecture that aims to achieve effective distribution, increase availability and decrease latency. In the proposed architecture, the main functional points of the Attribute-based Access Control are distributed to provide policy decision and policy information mechanisms in fog nodes, locating these functions near end nodes. To evaluate the proposed architecture, an access control engine based on the Attribute-based Access Control was built using the Balana library and simulated using EdgeCloudSim to compare it to the traditional cloud-based architecture. The experiments show that the fog-based architecture provides robust results in terms of reducing latency in making access decisions.

As today's Information Technology (IT) becomes more global and specialized the importance of Information Technology Architecture (ITA). Based on the case study of e-commerce, this paper presents a systematic approach to Information Strategy Planning (ISP) with ITA. To implementation of strategic approach, ITA is developed to establish e-commerce projects. It is believed that the Chief Information Officer (CIO) will be more receptive to results that include ISP and ITA are combined simultaneously.

It was on the rise importantly to provide the efficient management process of the organization for dealing with the change about information and business management quickly and consistently. It was suggested with the architectural model on information technology to provide it in theoretically. The Federal Government and budget organization of the USA used it on actual business and the terms of EA (Enterprise Architecture) and are raising the efficiency of management. NCA (National Computerization Agency) of Korea published the book - "The Research about establishing ITA (Information Technology Architecture) and appling the standards". After being applied the model on MOGAHA (Ministry of Government Administration and Home Affairs) and MIC(Minisstry of Information and Communication), the concrete case was made. MOMAF (Ministry of Maritime Affairs and Fisheries) drove the leading model. The report ascertained the basic contents of ITA and researched the case of USA, MOGAHA, MIC, and tried to analyze the contents of appling maritime and fisheries area. The report contained the definition of purpose through analyzing environment and establishing the vision and the principles based on them. The report also contained the contents of architecture based on the standard of NCA - "The Government Standard Meta Model version 2.0" - and researched the MOMAF's Reference model using Government Reference model. The report established the investment architecture and the process of information technology asset management. It ascertained the characteristic of maritime & fisheries area and the subject of developing the MOMAF's ITA sustainably.

본 논문은 최근 관심이 증대되고 있는 '정보기술 아키텍처'를 국가차원의 전자상거래 아키텍처 프레임워크 설정에 적용해 본 것이다. 저자는 기존 정보기술 아키텍처 프레임워크 즉,자크만 프레임워크, C4ISR 아키텍처 프레임워크, 미국 연방정부 아키텍처 프레임워크 등을 확장한 VMT 프레임워크를 제시 하였다. VMT는 전자상거래를 3개의 축, 즉 관점(기획/계획, 시스템 분석, 설계, 구현 등), 대상(데이터, 기능, 네트워크, 행위자, 사건, 망침) 기간(단기, 중기, 장기)에 따라 정의할 수 있는 개념적 틀로서 전자상거래 관련 이해 당사자들은 이를 통해 전자상거래에 대해 보다 포괄적인 이해와 접근을 할 수 있을 것으로 판단된다.

As the amount of IT investment and the complexity of information systems in public agencies have been increased, efficient and structured management of IT systems is more emphasized. For the Korean government. ITA (Information Technology Architecture) is one of the core parts of the e-Government initiative. Also introducing and managing ITA in organizations is mandated by law in Korea. The objective of the paper is to study whether using ITA in public agencies is related with their IT capability and IT performance or not. A questionnaire had been designed for the purpose, and a survey had been performed on Korean public agencies. The survey results show that using ITA has influence on relation and technology capability. However, ITA does not influence on human capability and IT performance. The reason why using ITA is linked to relation and technology capability is that ITA includes relationship between both business and technology. Also ITA provides a technical reference model (TRM) and standard profile (SP), so it has influence on technology capability.

본 연구는 Ansoff의 "전략적 성공모델"에 의거하여 조직 정보기술전략의 도달 가능한 최고 성과는 경 영 환경의 역동성(turbulence)과 정보기술전략의 공격도(aggressiveness), 정보기술역량(capability)간의 일치에 의한다는 가설을 검증하였다. 정보기술전략 공격도와 정보기술역량을 차별화한기 위하여 정보기술아키텍처라는 개념을 원용하였다. 즉, 정보기술전략의 공격도는 아키텍쳐를 의미하는데, 이는 정보기술역량이 경영자의 장래 정보기술에 대한 태도를 의미하는데 반하여 정보기술아키텍쳐는 현재 조직이 보유한 기술적 역량을 의미한다. 본 연구는 정보기술아키텍쳐와 경영환경의 역동성, 정보기술역량간의 수준의 일치가 조직성과에 유의미하다는 결론을 제공한다. 즉 경영환경의 역동성, 정보기술전략과 정보기술아키텍쳐의 일치는, 특히 경영환경이 역동적인 상황에서 더욱 조직성과에 유익한 결과를 가져올 수 있다는 근거를 통계적으로 증명한다.

Mobile devices, such as PDAs, portable multimedia players, are more likely to encompass large storage devices with prevalance of high-quality multimedia contents. This paper proposes an object-based multimedia contents storage architecture that employs the object-based storage device model and the iSCSI protocol. It also provides a multimedia content player that operates directly with the proposed storage architecture. We implement both the proposed storage architecture and the multimedia content player upon the Linux environment. Performance evaluation by playing MP3 multimedia contents reveals that the proposed storage architecture reduces the total power consumption by 9%, compared with an existing networked storage. This enhancement is mainly contributed to the fact that a large portion of the file system is moved into the object-based multimedia contents storage from the mobile device.

Generally, because individual agricultural product possesses its own distinctive characteristics and shows different characteristics at each stage of the agricultural supply chain, it is necessary to develop a proper enterprise architecture for managing information system. In this paper, we propose an enterprise architecture based on RFID/USN technology that can be used as a reference enterprise architecture for u-IT application in the agriculture sectors, which is called the u-Farm enterprise architecture with taking heterogeneous characteristics of agricultural products into account for. In addition, we also developed the RFID/USN middleware platform as a core infrastructure technology. Fo evaluation of the performance of the proposed u-Farm architecture and the RFID/USN middleware platform, the field-trial evaluation at the apple Agricultural Processing Center (APC) has been executed and the results shows that the proposed architecture and platform perform well in terms of information integration over the whole SCM process from the farming stage to delivering statge to the customers. It is expected that the proposed u-Farm enterprise architecture can be utilized as a standard information architecture, and the RFID/USN middleware platform can be a infrastructure platform for future u-IT based information technology applications and services in the agricultural environment.

Native information provider(IP) anycast suffers from routing scalability issues and the lack of stateful communication support. For this reason, we propose architecture for scalable and transparent anycast services(ASTAS), a proxy-based architecture that provides support for stateful anycast communications, while retaining the transparency offered by native anycast. Dynamic resource assignment for each initiated session guarantees that a connection is established with the most suitable target server, based on network and server conditions. Traffic engineering in the overlay can be realized in an effective way due to the dissemination of aggregated state information in the anycast overlay. To minimize the total deployment cost for ASTAS architectures, we propose optimized proxy placement and path finding heuristics based on look-ahead information gathered in network nodes. Contrary to a regular integer linear program(ILP) formulation, these heuristics allow to optimize proxy placement in large networks. A use case on a European reference network illustrates that lower proxy costs enable proxy deployment closer to the end-users, resulting in a reduced network load.
