국내 방산분야의 기술적 성장과 수출 증대가 괄목함에 따라, 국가안보적 위협을 방지하기 위한 방위산업 분야 기술보호의 중요성이 강조되고 있으므로 기술보호 제도의 확립 및 수행이 필요하다. 특히 무기 시스템으로부터 중요기술을 불법으로 탈취하는 Tampering 시도에 대응하기 위한 Anti-Tampering 기법의 도입 필요성이 대두되고 있으나, 아직까지는 관련제도가 갖춰지지 않았고 기술자료 유출 예방 위주 수준의 활동이 이루어지고 있다. 선행연구로서 특정 기술 보호기법에 대한 기술적 연구와 동향 분석, 일부 절차를 적용한 Anti-Tampering 적용방안 등이 발표되었으며, 최근에는 위험관리 절차를 기반으로 보호대상 기술을 선정하는 방법이 연구되었다. 하지만 기존 연구들은 무기 시스템의 Life-cycle 차원에서 획득 프로세스와 연계하기에 용이하지 않거나, 실제로 개발 및 평가에서 활용하기는 어려운 것으로 판단된다. 이러한 문제를 해결하는 한 방법으로, 본 논문에서는 Anti-Tampering 적용이 결정된 무기 시스템의 개발에 직접적으로 활용될 수 있는 Anti-Tampering 요구사항의 도출에 대하여 연구하였다. 구체적으로, 암호 모듈의 개발 및 검증에 적용되는 CMVP 표준인 ISO/IEC 19790을 기반으로 무기 시스템 개발에 필요한 요구사항 항목들을 도출하였으며, 기술검토회의 및 시험평가 등에서의 활용방안을 제시하였다. 귀납적 추론 및 비교평가를 통해 연구결과의 유용성을 확인하였다. 본 연구의 결과들을 활용하면, 국내개발 무기 시스템의 본격적인 기술보호 활동 수행에 도움이 될 것으로 기대된다.

A study on common modular design based on open standards to reduce the life cycle cost of ground weapon system is underway. Since the ground weapon system includes major mission equipment such as fire control system, it is essential to apply the concept of fault tolerance through automatic reconfiguration and blocking unspecified equipment through connectivity control. However, it is difficult to generalize due to the difference in operating characteristics for each system. In this paper, we propose a plug-and-play framework, which includes plug-and-play architecture and mechanism. The proposed method can be used in common by the application of each component as it is divided into a common service layer. In addition, the proposed connectivity control and autonomous reconfiguration method facilitates reflection of operating characteristics for each system. We constructed a verification environment that can simulate ground weapon systems and components, and verified that the proposed framework works through scenario-based functional tests.

The live fire test has been playing a critical role in evaluating the goals-to-meet of the weapon systems which utilize the power of explosives. As such, the successful development of the test systems therein is quite important. The test systems development covers that of ranges and facilities including system-level key components such as mission control, instrumentation or observation, safety control, electric power, launch pad, and so on. In addition, proper operational guidelines are needed with well-trained test and operation personnel. The emerging weapon systems to be deployed in future battle field would thus have to be more precise and dynamic, smarter, thereby requiring more elaboration. Furthermore, the safety consideration is becoming more serious due to the ever-increasing power of explosives. In such a situation, development of live fire test systems seems to be challenging. The objective of the paper is on how to incorporate the safety and other requirements in the development. To achieve the goal, an architectural approach is adopted by utilizing both the system components relationship and safety requirement when advanced instrumentation technology needs to be developed and deteriorated components of the range are replaced. As an evaluation method, it is studied how the level of maturity of the test systems development can be assessed particularly with the safety requirement considered. Based on the concepts of both systems engineering and SoS (System-of-Systems) engineering process, an enhanced model for the system readiness level is proposed by incorporating safety. The maturity model proposed would be helpful in assessing the maturity of safety-critical systems development whereas the costing model would provide a guide on how the reasonable test resource allocation plan can be made, which is based on the live fire test scenario of future complex weapon systems such as SoS.

As the proportion of software in weapon systems increases, the impact of software on the overall system is growing. As a result, software quality management becomes important, and related regulations and work manuals for quality assurance activities at each stage in the R & D process are becoming more sophisticated. However, due to the characteristics of the weapon system software that is developed as a customized form for the purpose of a specific mission, there are limits to specifying and definitizing the detailed requirements (upper and lower level) according to various operational concepts during the development process. Due to this, software modification (patch change, shape change due to upgrade, etc.) occurs on account of many defects and performance improvement in the mass production and operation stage after the development is completed. In this study, we analyze the characteristics of these weapon system softwares and propose quality improvement methods based on ISO / IEC / IEEE 29119 test method.

There are many technical datum in related with design, test & evaluation and logistic support which will be exchanged between geographically isolated units and heterogeneous hardwares & softwares in developing and operating the weapon systems. The paper proposes the conceptual database schema to establish configuration management information systems in which these datum can be automatically interchanged, tracked, audited and status-accounted without errors under the various environments. The paper investigates how to identify and classify the data in accordance with document identification, task analysis, system development, logistic support, system test & evaluation and data management. Furthermore, the investigation includes drawing the subject areas and modeling the conceptual database schema to explain the relationships between these datum. Thus, the paper results in the conceptual framework and data models of configuration management information systems, while additional customization efforts be required in applying the models to a specific weapon systems R&D.
