The limits of current DN(Defense networks), private and closed network, become to reality; for Example, high expense of construction and maintenance of networks, restriction of new subscribers on DN. Therefore, a network using web environment that reflect fast development of If and IS(Information Security) technology is demanded for MND. Meeting the requirement of reliable IS system and extension and improvement of DN using common network, we can reduce the expense to extend, maintain, repair DN, form the environment that makes military business cooperate better with civil company and government agency, advance implementing Defense computing and networking service for field small size units that was a exception of Defense digitalization. But it is essential to construct DN based on common network that there are security requisites; confidentiality, integrity, availability, efficiency, log, backup, restoration, that have to be realized at demanding level for IS. This thesis suggested four measurements; replacement DN with common network to resolve the requirements of building new network and improvement of performance for private DN, linkage with common network for new requirement, distribution of traffic using common network, configuration of DN using Internet and Proposed a refinement of IS management organization to treat security threat of common network flexibly, and LAN IS standard model of DN based on the web environment.

RMF(사이버보안 위험관리 프레임워크)는 지금 현재 국방영역을 넘어 미 연방정부 전체에 통용되는 보다 강화된 미 국방 사이버보안 프레임워크이다. 최근 십여년 간 미국이 접한 비정규전에 있어 사이버전이 차지하는 비율, 특히 중국과 북한으로부터 유발된 사이버공격 비중은 점점 더 증대되고 있다. 결국 미국은 범정부 차원의 보다 강화된 사이버보안 정책을 마련하고자 RMF체계를 새롭게 구축중이며, 미 국방부는 연방정부차원을 넘어 동맹국 간에도 미 국방 RMF평가 정책을 확대해 나가고자 한다. 이미 한국군도 F-35A 획득 시 RMF 적용방침을 통보한 미측 요구로 RMF를 적용한 바 있다. 한국군의 RMF적용은 더 이상 피할 수 없는 대세이다. 이제 우리군은 성공적인 한국형 RMF체계 조기 구축을 위해 무엇을 준비해야 하는지 진지하게 고민해야 할 시점이다.

The SONAR waterfall image(SWI) is used typically to target detection in SONAR operation and is managed with additional data linked in the naval combat system. The SWI and additional data are very important to classify a kind of target. Although additional data of the SWI is essential and must be kept together with the SWI, it was stored separately in the current system. In this paper, we propose an improved information management method in the naval combat system, where additional data can be contained in the SWI together by using information hiding techniques. The experimental results show that the effectiveness of information hiding techniques in the naval combat system. It is demonstrated that the information hiding techniques can be applied to the SWI that can make the naval combat system to be robust and secure.

The Ministry of National Defense announced 'Defense Reform 2.0' that aims to strengthen the country's security for decrease of regional uncertainties, growing requirements for advanced technologies, and a need for more efficiency in the Republic of Korea(RoK) Armed Forces this year. It said RoK Armed Forces have to change efficiently in preparation for rapid decline in military service resources as demographic cliff turning into reality, and the rapid evolution of the "battlefield environment" caused by developments in military science and technologies. RoK Navy combat Management System(CMS) made by domestic proprietary technology since 2000s and development centered on Agency for Defense Development require design changes for added requirements. So in this paper, I propose method of design a low cost and high efficiency navy CMS architecture based on high performance server and virtualization technology. And I create a test environment for analysis performance and compare the performance of proposed navy CMS and existing navy CMS.

소프트웨어를 안전하게 관리하기 위해 군은 RMF A&A(Risk Management Framework Assessment & Authorization) 표준에 따라 제품을 구매하고 관리한다. 해당 표준은 무기체계를 비롯한 군 IT 제품의 획득 체계에 관한 표준으로 제품에 대한 요구사항, 평가를 통한 구매, 유지보수를 다룬다. 해당 표준에 따르면 제품 개발활동에는 군에서 제시한 임무의 위험도가 반영되어야 한다. 즉, 개발사는 보안 내재화 및 공급망 보안을 통해 제시된 위험도를 완화하였고, RMF A&A의 보안 요구사항을 제대로 준수하였음을 입증하는 자료를 제출해야하고, 군에서는 개발사로부터 제출된 증거자료에 대한 평가를 통해 최종 획득 여부를 결정한다. 기존에 RMF A&A 실증 연구가 수행된 사례가 있다. 하지만, 해당 연구는 RMF A&A의 전체 단계가 아닌 일부분에 대해서만 다루고 있고, 해당 연구의 실증 사례가 대외비인 관계로 상세한 정보가 공개되지 않아 실제 산업 환경에 적용하는데 어려움이 있다. 이에 본 논문에서는 군의 위험도 측정 및 RMF A&A 관련 표준들을 분석하고, 이를 바탕으로 군 RMF A&A의 요구사항을 만족시킬 수 있는 증거자료 작성방안에 대해 제시한다. 또한, 제시한 방안을 실제 드론 시스템에 적용하여 작성된 평가 제출물이 RMF A&A의 요구사항에 부합한지 검증을 수행한다.

As the research work about XML based on the development of Internet and according to the information exchange standard is being carried out, the need of discovering new methods to store XML documents and manage them efficiently according to the frequency of large-capacity XML documents increases. Consequently, as a kind of back-end database system, XML storage systems such as RDBMS, OODBMS and Native XML DBMS etc. are coming forth in order to save XML documents. It is an urgent task to make comparisons among usage expense, function comparison storage, inquiry, and manage dimension for each DBMS. This paper makes an analysis and comparison of DTD-independent XML document access methods in RDBMS, OODBMS and Native XML DBMS for XML storage and management. After analyzing the advantages and disadvantages of each access method and comparing the function of typical commerce DBMS such as Oracle 8i, eXcelon and Tamino for finding the possibility of military applications, an another appropriate method to save XML documents is proposed as to find an implementation approach to save structural XML documents.

Security supports are a significant factor in mobile ad hoc networks. Especially in dynamic topologies, considering cluster, key management is essential to provide a secure system. Recently, Li-Liu proposed iD-based multiple key management scheme for cluster-based ad hoc networks. However, we found the security weakness of their scheme. In this paper, we analyze the security of Li-Liu's scheme and show that master secret key and fragment of the master secret key can be revealed to compromised CHs and nodes. Furthermore, we propose a solution to improve the scheme against disclosure of the share key and the master secret key even though system parameters are opened to compromised nodes and modify the Li-Liu's scheme fitted for a scalable networks. The improved IMKM scheme could be usefully applied in dynamic cluster-based MANETs such as the military battlefields, mobile marketplace and VANETs.

In light of the recent developments of transitory nature, it is likely that national defense decision-making will be more difficult to make for years to come. In other words, sudden changes in security environment would call into question the basic assumptions on which we have built our national defense planning and increase the number of the uncertain factors in the decision-making process; the subdivision and ramification of national defense management would increase the factors for decision-making and complicate even further the mutual interactions among these factors; the accelerated pace of sophistication and diversification of weapon systems and military technology would increase the risk of failure and system costs geometrically; and the reduced level of acceptance among the people on the sanctification of national defense in proportion to the rapid progress toward a more democratic and industrial society would engender an increased criticism or checking role by the National Assembly or by the mass media. As the changes in national defense environment and conditions create an innumerable number of new tasks, this paper intends to suggest a few core policy measures to improve the quality of national defense decision-making. More specifically, it proposes to 1) eradicate entirely the bureaucratic behavior and tendencies; 2) utilize actively the brain staff for quality assurance of decision-making; 3) and introduce and apply as a whole set, a total system, or an incorporated pack age the PPBEES(Planning-Programming-Budgeting-Executing-Evaluating-System)/LCMM (Life-Cycle Management Model for System Acquision), the OR/SA(Operations Research/Systems Analysis), and DMIS (Defense Management Information System).

4차 산업혁명 시대에는 보안 네트워킹 기술이 국방 무기 체계에서 필수적인 역할을 하고 있다. 정보보안을 위해 암호 기술을 사용한다. 암호 기술의 안전성은 케르크호프의 원칙(Kerchoff's principle)에서 강조하듯 암호 기술 알고리즘이 아닌 암호 기술의 안전한 키 관리에 기반한다. 그러나, 전장 환경에서 무기체계의 잦은 이동으로 인해 네트워크 구조가 변하며 전통적인 중앙 집중식 키 관리 방법을 사용하기가 어렵다. 또한 IoBT(Internet of Battlefield Things) 환경에서 사용되는 각 노드의 시스템 자원은 크기, 용량, 성능이 제한되므로 기존의 키 관리 알고리즘보다 계산량과 복잡도가 적은 경량화 키 관리 시스템이 필요하다. 본 논문은 IoBT 환경을 위한 경량화 방식의 새로운 키 위탁 방식을 제안한다. 제안된 기법의 안전성과 성능을 수치 분석과 시뮬레이션을 통해 검증하였다.
