최근 인터넷을 통한 전자상거래와 금융서비스가 널리 확산됨에 따라 인터넷 상에서 전송되는 정보의 안전과 신뢰성 확보에 필요한 정보보호 기술의 표준화 요구가 높아지고 있다. 이러한 인터넷 정보보호 기술의 표준화는 인터넷의 통일성과 표준을 유지하기 위해 설립된 IETF에 의해 수행되고 있으며, 공개키 기반구조(Public Key Infrastructure)에 관한 기술은 PKIX(Public Key Infrastructure X.509) 작업반에서 그 표준화를 담당하고 있다. 본 고에서는 IETF PKIX 작업반의 공개키 기반구조 관련 표준을 조사하였으며 최근의 표준화 활동을 분석한다.

전자정부 구현에 있어 온라인상에서 유통되는 각종 행정정보에 대한 정보보호는 필수적인 선결 조건이다. 미국 등 각국에서는 전자전부의 정보보호 기반 구축을 하여 가상행정을 환경에서 당사자의 신원 확인,기밀성,무결성,부인봉쇄 등을 보장하는 정부차원의 PKI(Public Key Infrastructure)를 구축.운영 중에 있다. 본 논문에서는 주요 정보의 비밀성, 무결성 등을 보장하는 정부차원의 정보보호체계 구축을 위해 2000년부터 추진되고 있는 GPKI(Govermment Public Key Infrastructure) 구축 현황, 인증서비스 현황 및 향후 방향에 대하여 논하였다.

Low-rise residential community is the most popular type (51%) of residential neighborhoods in Seoul. Currently, there is a shortage of public facilities needed for living conditions and the quality of life in low-rise residential areas. This study defines 'public facility' as infrastructure to improve the living environment and used by residents jointly in low-rise residential areas. In this regard, this study analyzes current legal and institutional standards, latest trends in public facility of apartments, and residents' demand and satisfaction level in order to find out the criteria for installation of priority public facilities. As a result, the essential facility basically conforms to the number of household which is the standard of the facility supply in apartment. However, considering the limitations on the accessibility due to low density, it should consider two standards at the same time: the number of household and distance (radius of neighborhood). In conclusion, it is necessary to install legally prescribed facilities according to the number of household and distance: 500 households facilities in 250m radius neighborhood and 1,000 households facilities in 400m radius neighborhood. Also, considering the reality of low-rise residential area, it is necessary to integrate some facilities that can be functionally linked to improve level of utility and efficiency of operation and management. It is expected that the output of this study can be applied to institutionalize of the legal basis for the public facility of low-rise residential community.

With the advent of new order of international competition, the technology Policy of Korea has been changed from vertical one which focuses on specific technologies or selective industries to a horizontal one which supports R&D activities on a neutral basis. TIP(Technology Infrastructure Policy) is WTO free in the sense that it is Indirect method of supporting technology development and properly defined as a part of government role by OECD. Technology infrastructure is embodied in human capital, and includes also elements of physical capital and knowledge. Hence it is more differentiated than, and distinguished from conventional infrastructure. It implies a need for carefully designed strategy with the recognition of those differences. As a fundamental element of innovation and technological development, technology infrastructure should become the main focus of industrial technology Policy.

To provide a development strategy on the method which assesses a potential risk of nationwide emerging IT infrastructure in planning and design phase, and to classify the assessment result into 5 levels is the goal of this research. The development strategy provided in this paper could improve a benefit-cost-ratio of investments on emerging IT infrastructure. With a premature assessment of the potential risks of a nationwide emerging IT infrastructure which needs astronomical amount of public funds, it could show a way of systematic investments on security systems and improve a benefit-cost-ratio of investments on emerging IT infrastructure. Also, this approach might improve the safety of nationwide IT infrastructure. It could identify and provide an optimized solution for the potential risks of nationwide IT infrastructure.

As demands and interests in visiting rural village increases, government authorities are promoting eco and green tour village development project through plural functions of rural village. The purpose of this study is to understand infrastructure improvement direction by researching the case study of general rural villages' changing to eco and green tourism villages. As for the research method, the character of each village was verified, then the case studies of improvement by life infrastructure using the identity of villages were analyzed. Finally, it was found that infrastructure through public facilities improvement and environment improvement project was expanded and relaxative and experiential space was offered by creating tour infrastructure using the identity of villages. Also, it was shown that farming infrastructure creating project was executed to promote the income base of locals.

This paper discusses cases of infrastructure asset management in the U.S., Canada, and Australia and investigates infrastructure management in Korea in order to set the direction for the asset management improvement. The definitions of infrastructure asset management from various entities are introduced and implementation framework and organizational structures are described. The investigation on Korean public asset management practices finds the strong and weak points and defines the requirements and considerations to further improve the current practices. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

In the field of secure information systems including electronic commerces, public key infrastructure(PKI) is widely used for secure services. The more PKI domains are established, the more needs are required for cross-domain certifications. Furthermore, each country has many certificate authorities(CA) which require more complex cross certification: We may need a fast algorithm in order to find the possible certification paths. This will be more indispensible in the growing PKI systems. We designed and implemented the high-speed certification path discovery algorithm. Also, we investigated the feature of operation of the system.

The recent technological and industrial revolution dictates a new approach in constructing Korean Information Infrastructure. Lacking past data on the newly emerging markets, econometrics methodologies cannot accurately forecast future path of advanced networks, let alone dynamic impacts of public policies. In this paper, we have built a system dynamics model of the Korean Information Infrastructure and simulated diverse policy measures including market integration and government initiative in investment for experimenting their effectiveness. The most counterintuitive result of our research is that the market integration policy will facilitate CATV networks at an early stage until the year 2010, but will result in a diminished market size in the long run. With the system dynamics approach, we can enhance our understanding of the complex policy systems and get valuable insights through learning by modeling and simulation.

Since 'Act on Private Participation in Infrastructure' were changed in January 2005, BTL(Build-Transfer-Lease) projects of Private Participation in Infrastructure was introduced in the domestic construction market for the purpose of providing public facilities with the public. Selecting the most qualified Promoter should be considered discreetly in BTL projects because BTL projects is for projects with approximately thirty year project life cycle, plan, construction, operating, maintenance and obviously the success of the project totally depends on the capability and role of Promoter. However, score for cost is likely to influence selecting Promoter to take the project. Accordingly, low bid contract with too much competition could decrease the quality of the construction plan and operating plan. Thus, this study did preliminary research and documents on problems of evaluation criteria for selecting Promoter in BTL projects, and proposed improvement factors by doing questionnaire over specialists of each field.
