드론은 군용에서부터, 공공 관제 및 모니터링, 촬영 및 취미, 배송 서비스에 이르기까지 다양하게 활용되고 있다. 그러나 드론에 내장된 센서 값 조작이나 수집 데이터 누출, 통신 내용 도감청 및 GPS 신호 조작 등의 보안 취약점을 이용한 공격은 드론을 포획하거나 추락시키고 중요한 데이터를 탈취하는 등 심각한 문제를 야기할 수 있다. 이러한 보안 취약점을 해결하기 위해 드론 전용 난수 생성기와 통신보호를 위한 암호프로토콜, 화이트박스 암호를 통한 정보보호 및 신호 인증을 통한 GPS 스푸핑 탑지 기법 등 안전한 드론 보안 메커니즘이 활발히 연구되고 있다. 이에 본 논문에서는 드론 시스템의 구성 요소별 보안 위협 요소를 살펴보고, 보안 위협 사례를 공격 유형별로 분석한다. 또한 이러한 보안 위협들에 대응하기 위해 드론에 적용된 암호 기술 현황에 대해 살펴본다.

Recently, as the technology of drones develops, a malicious attack using a drones becomes a problem, and an anti-drone technology for detecting an attack dron for a malicious attack is required. However, currently used drone detection systems are expensive and require a lot of manpower. Therefore, in this paper, we propose an anti - drone method using the analysis and algorithms of the anti - drone that can monitor the attack drones. In this paper, we identify and detect attack drones using sniffing, and propose capture and deception algorithm through spoofing using current GPS based detection system.

North Korea's rapidly advancing drone development and operational capabilities have become a significant threat to South Korea's security. The drone incursions by North Korea in 2014, 2017, and 2022 demonstrate the technological advancement and provocative potential of North Korean drones. This study aims to closely analyze the military threats posed by North Korean drones and seek effective countermeasures. The research examines the development level of North Korean drone technology, its military applications, the characteristics and patterns of recent drone incursions, the adequacy and limitations of South Korea's current response systems, and future countermeasures. For this purpose, domestic and international research literature and media reports were reviewed, and specific North Korean drone incursion cases were analyzed. The results indicate that North Korea's small drones possess technological features such as small size, low altitude, low-speed flight, long-duration flight, and reconnaissance equipment. These drones pose threats that can be utilized for reconnaissance, surveillance, surprise attacks, and terrorism. Additionally, South Korea's current response systems reveal limitations such as inadequate detection and identification capabilities, low interception success rates, lack of an integrated response system, and insufficient specialized personnel and equipment. Therefore, this study suggests various technical, policy, and international cooperative countermeasures, including the development of drone detection and identification technologies, the utilization of diverse drone neutralization technologies, the establishment of legal and institutional foundations, the construction of a cooperative framework among relevant agencies, and the strengthening of international cooperation. The study particularly emphasizes the importance of raising awareness of the North Korean drone threat across South Korean society and unifying national efforts to respond to these threats.

본 논문에서는 OpenCV의 Marker Detection 기술을 이용하여 특정지점의 마커를 영상처리기술로 인식하여 드론의 자동 이착륙 및 주변 위기상황, 미션수행 등을 마커를 통해서 드론에게 전달하여 비행 제어할 수 있는 체계를 개발한다. 드론은 OpenCV Aruco모듈을 이용하여 Marker ID별로 특정 명령어를 데이터 베이스와 비교하여 비행제어 명령을 수행한다. 지상에서는 마커의 변경을 통해서 실시간으로 미션변경을 할 수 있다. 이를 통해 드론은 제어용 송수신 채널을 통해서 통신을 하고는 있으나, 주파수 채널수가 제한이 되어 있으므로 구체적인 비행 제어 명령을 마커를 통해 이착륙시 추가적이며, 자동적인 진행이 가능하다.

드론은 초기에 주로 군사적 목적으로 사용되었으나, ICT 기술이 발전함에 따라 다양한 산업 서비스에 활용되고 있다. 그러나 드론이 네트워크에 연결됨으로써 많은 보안위협과 취약점에 노출되었으며, 이는 드론 탈취, 정보유출, 서비스 장애 등의 심각한 피해를 야기할 수 있다. 따라서, 본 논문에서는 기존 드론의 보안위협 뿐만 아니라 다가올 양자시대의 보안위협에 대비하여 안전한 드론 서비스를 제공할 수 있는 PQC 기반 보안채널 통신기술을 제안하고 구현한다.

This study examined the factors affecting the behavioral intention for agricultural drone service. The survey results of 324 agricultural-related workers were analyzed using SPSS v22.0 and PROCESS macro v3.4. The effects of technology acceptance factors by UTAUT on the behavioral intention for agricultural drone service and the mediating effects of perceived benefits were analyzed. The results are as follows: First, the technology acceptance factors had positive (+) effects on perceived benefits and behavioral intention for agricultural drone service. Second, economics mediated between factors excluding performance expectancy and intention, convenience also mediated between factors excluding social influence and intention, and there was no significant mediating effect of practicality benefits. In the future, a further research is required for people trained in agriculture or drone or had a drone license.

Research on mapping levees is an important task for assessing levee stability. The drone imagery acquired in river basins is useful for generating real-time levee maps. This research proposes a robust methodology for mapping levees in river basins using the drone imagery. In the first step, the multiple imagery taken in the test bed was acquired by the drone. Then, the orthorectified image and DEM (Digital Elevation Model) were generated by the photogrammetry and image processing process. Finally, the significant features on levee surfaces such as levee tops, levee lines, levee slopes, eroded areas were detected from the generated DEM and orthorectified image by manual labors and automatic methods. In future research, the automatic procedure for identifying the significant levee features from the drone imagery would be proposed.
