In this paper, we propose schemes of blockchain utilization in tactical communication environment. The military tactical communication environment has similar characteristics with blockchain network such as distributed architecture, decentralization, and the need for data integrity. A communication node constituting a tactical communication network is constituted by a system capable of configuring and connecting a network for each node. When a communication node, having such capabilities, is configured as a node of blockchain network, various functions could be performed. In this paper, we propose utilization schemes of authentication, integrity, record management, and privilege control based blockchain technology. Functions for authentication, integrity verification, and record management need to ensure the stored data and could track history. The requirement of function’s characteristics are matched to blockchain which is storing data sequentially and difficult to hack data, so that it could perform functionally and sufficiently well. Functions for authority control should be able to assign different privileges according to the state of the requestor. Smart contract will function when certain conditions are satisfied and it will be able to perform its functions by using it. In this paper, we will look over functions and utilization schemes of blockchain technology which could reliably share and synchronize data in a tactical communication environment composed of distributed network environment.

다중 무인기 조종통제를 위한 데이터 처리 구조에 관한 연구
유인덕(In-Deok Yoo),황찬호(Chan-Ho Hwang),이우신(Woo-Sin Lee),진소연(So-Yeon Jin),김영돈(Young-Don Kim) 대한전자공학회 2017 전자공학회논문지 Vol.54 No.11
네트워크 중심전(Network Centric Warfare)으로 변해가는 현대전에서 무인 항공기 시스템은 감시 정찰 임무를 수행 할 수 있는 체계로서 주목 받고 있다. 무인기(Unmanned Aerial Vehicle)와 지상통제 시스템(Ground Control System)으로 구성되는 무인 항공기 시스템에서 디지털 통신 기반의 통신로 역할을 수행하는 데이터링크 기술은 대용량 데이터 전송뿐만 아니라 좁은 대역폭에서 다수의 무인기와 소용량 데이터 송신이 가능하도록 발전해나가고 있다. 여러 대의 다중 무인기를 조종통제하기 위해서는 단독 운용구조의 통신과는 다른 방식의 데이터 처리 구조를 필요로 한다. 본 논문에서는 다중 무인기 조종통제를 위한 1:N 통신 구조의 특징을 분석하고 효율적으로 데이터를 처리 할 수 있는 구조를 제안한다. 제안하는 데이터 처리 구조를 통해서 무인기 제어를 위한 데이터가 트래픽 데이터량과 무관하게 일정한 전달 시간을 보장함을 확인한다. In modern warfare which is transforming into Network Centric Warfare(NCW), the Unmanned Aircraft System(UAS) is attracting attention as a system capable of performing surveillance and reconnaissance missions. The UAS consists of UAV(Unmanned Aerial Vehicle) and ground control system, the data link plays a role of communication. Data link technology based on digital communication is being developed to enable large number of UAV and small capacity data transmission in narrow bandwidth as well as large capacity data transmission. Controlling multiple UAVs requires a data processing structure that is different from that of a single operation. In this paper, we analyze the characteristics of 1:N communication structure for multi-UAVs control and propose a structure that can process data efficiently. Through the proposed data processing structure, it is confirmed that data for UAV control guarantees constant transmission time regardless of traffic data amount.

군용 무인기 체계 연동 상호 운용성 최신화를 위한 STANAG-4586 기반 무인기 표준화 적용 방안
김학준(Hack-Joon Kim),윤창배(Chang-Bae Yoon),홍수운(Su-Woon Hong),이우신(Woo-Sin Lee),유인덕(In-Deok Yoo),조세현(Se-Hyeon Jo) 한국컴퓨터정보학회 2019 韓國컴퓨터情報學會論文誌 Vol.24 No.6
With the development of various types of military Unmanned Aircraft(UA)s, the need for interworking and integration between different platforms gradually increased. In order to ensure interoperability at each military UA System(UAS) level, North Atlantic Treaty Organization(NATO) has established STANAG-4586 "Standard Interfaces of Unmanned Aircraft(UA) Control Systems(UCS) for NATO UA Interoperability-Interface Control Document". This paper looks at the basic design structure of STANAG-4586 and the changes on Edition 4 to enhance joint operational capability through reflecting and updating the interoperability design of the military UAS. In particular, we analyze the enhanced Datalink Transition/Handover Procedure and Autonomous functions, one of the biggest features added to the edition. Through this, we propose a modification of UA data link exclusive control using UA Bypass structure, which was impossible in the one-to-one communication structure between existing UA and Core UCS(CUCS). We also suggest ways to improve UA operational reliability by applying Autonomous Functions that directly decides how to deal with emergency situations, rather than by a remote operator over CUCS.
