The paradigm of war is basically changed by development of information and communication technologies. One of the paradigms in future war is NCW(Network-Centric Warfare) that is purposed of achievement in information-superiority. In this future war, the level of menace and fragility is rapidly increased in information-security according to the massive information and complex system. Therefore the Korean army is developing the information-security technologies for NCW. But, until now patent analysis concerning NCW has not performed. In this paper, we suggest a meaningful data for efficient R&D through patent analysis of information-security technologies on NCW.

This paper analyzes the intention of the PRC (People's Republic of China) to establish and operate CADIZ to implement the government's maritime policy and strategy and to project its air power in preparation for maritime provocation and contingency, especially over the area where East Asia countries have claimed to have maritime jurisdiction over one another. This paper is also intended to guide the Republic of Korea's response measures for coping with the maritime intention and threat of China by such measures as reinforcing military power, constructing the strategic air base in Jeju, and expanding the present KADIZ.

The Cognitive Radio (CR) paradigm in tactical ad hoc networks is an important element of future military communications for network-centric warfare. This paper presents a novel Cognitive Link State Routing protocol for CR-based tactical ad hoc networks. The proposed scheme provides prompt and reliable routes for Primary User (PU) activity through procedures that incorporate two main functions: PU-aware power adaptation and channel switching. For the PU-aware power adaptation, closer multipoint relay nodes are selected to prevent network partition and ensure successful PU communication. The PU-aware channel switching is proactively conducted using control messages to switch to a new available channel based on a common channel list. Our simulation study based on the ns-3 simulator demonstrates that the proposed routing scheme delivers significantly improved performance in terms of average end-to-end delay, jitter, and packet delivery ratio.

The aspect of future warfare is NCW(Network Centric Warfare) in accordance with the IT development, so MND have the planning of M-BcN(Military Broadband convergence Network) establishment as the basic system of NCW by the end of 2008. IPv6 address must be managed systematically as a essential element of NCW. In the previous study, it is designed on the basis of the present military information communication network topology. However, it makes some problems. First, it is difficult for present topology to adapt the future M-BcN which is different from the present military network topology. Second, it has defects of inefficiency of route aggregation and enlargement of routing table size. In this paper, we improved the route aggregation and routing table size by assigning the hierarchical address on the basis of M-BcN topology and adjusting the position of field identifying service network. Furthermore, it is proved by the network simulation program(OPNET 12.0).

As the information age comes out, the aspect of future war brings about the many changes in terms of war-fighting environment. Accordingly, information superiority and intelligence-centric warfare have been important and new war-fighting concept such as NCW(network centric warfare) have been turned up. This paper proposed all-weather core-strategy communications systems guaranteeing not only the real-time transmission of the information collected in a battlefield and expansion, automation, and rapidity of a battlefield but also broadband, mobility, survivability, and flexibility. The proposed military satellite communications system is classified into wideband mass capacity link, survivability, and the system supporting OTM(on the move) communication for the real-time transmission of battlefield information. This paper analyzed the essential operation concepts and core schemes of the U.S. Army's next generation system, TSAT(Transformational Satellite Communication System). Base on the analysis results, this paper proposed that the architecture of next generation military satellite communications systems for NCW have to provide the data rate, anti-jamming capability, network control and management capability which are optimally adaptable for the wireless channel environments such as jamming and interference and to support the variety of platforms like high-speed mobile vehicles, micromini devices, super-high speed unmanned aerial vehicles. Finally, this paper also proposed that next generation military satellite communications systems need the technologies such as the adaptable multi-antenna, laser link, and next-generation anti-jamming waveform.

In this study, I analyzed the increased threat of cyber warfare and the threat of reality about what is happening around the currently. And to prepare for it, I proposed the fact how main developed countries deal with cyber warfare. Also, I presented North Korea's cyber warfare threat which is equipped with world's top 3 cyber warfare performance and the way how their strategy influence to South Korea's national security. Moreever, I studied the existing North Korea's cyber warfare threat and the way how, how South Korea deal with it and prepare to against expected threat of cyber warfare in future.

The Network-Centric warfare over weapon data link networks has been developed for the recent decade. Since the US navy had begun to develop tactical digital information chain, it has gradually transformed into weapon data link technology. As data link network system and its protocol have been advanced into high-technology, focusing and targeting on moving targets become possible in net-enabled environments. However, it is difficult to identify the primary information from numerous battlefields and understanding approaches to damage a target in a timely manner. In this paper, to better understand the targeting assessment, we suggest a specific solution: Bomb Hit Indication(BHI) using information in weapon data link messages. In order to prove our suggestion, we implement the BHI solution and apply it into the weapon data link integrating system.

This paper focuses on analyzing the modern warfare and weapon systems supported by improved GPS informations. The GPS capability was investigated through the real experimental test for verifying the most recent GPS features under its modernization processing. And then it was verified that such capabilities, accuracy and availability, of a typical L1, C/A code GPS receiver are equivalent to the military receiver's ones. It was also sure that the influence of GPS improved informations on NCW(Network-Centric Warfare), PGM(Precision Guided Munition) and C4SIR(Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) should be increased and the modern warfare may be strongly dependent on GNSS informations.

The future battlefield environment has changed platform centric warfare into a network centric warfare. The NCO is a operational concept to improve combat power through information sharing, shared situational awareness, decision making and synchronized action based on powerful network grid. In addition, these operational environment is composed of physical, information, cognitive and social domains. The platform environment system is associated with the OSI 7 layer. However, OSI 7 layer is limited to express NCW environment including cognitive and social domains. Therefore, we requires a new model for expressing cognitive and social domains. After we developed a new model, this model applied to the NCW architecture taxonomy.

The Network Centric Warfare(NCW) is based on the linkage of forces by network to employ them as they are centralized, even though they are scattered. Also it can be used to overcome spatiotemporal obstacles. Under the concept of NCW, cognitive and social areas are getting more weight than information technology and physical ones. In this study we tried to investigate the affecting factors to execute NCW effectively by user's point of view to place the focus on cognitive and social aspects. We obtained some affirmative results that affect to conduct NCW in Korea. The advanced western NCW can be applicable in theoretically in Korea, however to employ NCW more effectively we need Korean style NCW which portrays the Korean realities and circumstances.
