IoT, Cloud, Bigdata, Mobile, AI, and 3D print, which are called as the main axis of the 4th Industrial Revolution, can be predicted to be changed when the technology is applied to the military. Especially, when I think about the purpose of battle, I think that IoT, Cloud, Bigdata, Mobile, and AI will play many role. Therefore, in this paper, Smart Military is defined as the future military that incorporates these five technologies, and the architecture is established and the appropriate information security model is studied. For this purpose, we studied the existing literature related to IoT, Cloud, Bigdata, Mobile, and AI and found common elements and presented the architecture accordingly. The proposed architecture is divided into strategic information security and tactical information security in the Smart Military environment. In the case of vulnerability, the information security is divided into strategic information security and tactical information security. If a protection system is established, it is expected that the optimum information protection can be constructed within an effective budget range.

최근 아파트의 월패드 해킹 사건과 같이 사물인터넷의 보안이 매우 심각한 상황이다. 사물인터넷은 자동화된 데이터 수집, 분석, 의사결정으로 효율성과 생산성 향상하고, 실시간으로 모니터링이 가능하면서 저비용으로 개발이 가능하다. 그리고 현재 인공 지능, 빅 데이터 및 클라우드 컴퓨팅 등 다양한 기술과 융합이 가능해 더욱 발전할 전망을 가지고 있다. 그러나 활용 범위가 갈수록 방대해지지만 현재 기술력으론 완벽한 보안을 실현하기가 어려운 것이 현실이다. 그리고 해킹의 대부분 직접적인 피해 당사자인 소비자들은 스마트홈이 주는 편의에 대해서만 알 뿐 보안 위협요소에는 잘 알지 못한다. 스마트홈의 보급이 빨라지고 있지만 정부 및 제조사에서 아직 스마트홈 보안에 관련한 홍보 및 교육이 따라가지 못하기 때문이다. 이러한 점을 보완하기 위해 본 논문에선 스마트홈의 보안 실태와 보안 요구사항에 대해서 다양한 방안을 살펴보고자 한다.

Smart home services are growing rapidly as the development of the Internet of Things (IoT) opens the era of the so-called "Connected Living." Although personal information leaks through smart home cameras are increasing, however, users-while concerned-tend to take passive measures to protect their personal information. This study theoretically explained and verified how to design effective software update notification messages for smart home cameras to ensure that users comply with the recommended security behavior (i.e., update installation). In a survey experiment participated in by 120 actual users, the effectiveness of both emotional appeals (i.e., security breach warning images for fear appeals) and rational appeals (i.e., loss-framed messages emphasizing the negative consequences of not installing the updates) were confirmed. The results of this study provide theoretical interpretations and practical guidelines on the message design features that are effective for threat appraisals (i.e., severity, vulnerability) of smart home camera users and their protection motivation.

Internet of Things(IoT) technologies should be able to communication with various embedded platforms. We will need to select an appropriate cryptographic algorithm in various embedded environments because we should consider security elements in IoT communications. Therefore the lightweight block cryptographic algorithm is essential for secure communication between these kinds of embedded platforms. However, the lightweight block cryptographic algorithm has a vulnerability which can be leaked in side channel analysis. Thus we also have to consider side channel countermeasure. In this paper, we will propose the scenario of side channel analysis and confirm the vulnerability for HIGHT algorithm which is composed of ARX structure. Additionally, we will suggest countermeasure for HIGHT against side channel analysis. Finally, we will explain how much the effectiveness can be provided through comparison between countermeasure for AES and HIGHT.

Recently interest in Internet of Things(IoT) is increasing, and a variety of the security technologies that are suitable for Internet of Things has being studied. Especially sensor network area of the device is an increased using and diversified for a low specification devices because of characteristic of the Internet of Things. However, there is difficulty in directly applying the security technologies such as the current authentication technologies to a low specification device, so also increased security threats. Therefore, authentication protocol between entities on the sensor network communication in Internet of Things has being studied. In 2014, Porambage et al. suggested elliptic curve cryptography algorithm based on a sensor network authentication protocol for advance security of Internet of Things environment, but it is vulnerability exists. Accordingly, in this paper, we analyze the vulnerability in elliptic curve cryptography algorithm based on authentication protocol proposed by Porambage et al. and propose an improved authentication protocol for sensor networks in Internet of Things environment.

Recently, smart home technology has been developed with a great response due to the convenience of home automation. Smart home technology provides various services by connecting various Internet of Things (IoT) and sensors to a home network through wired/wireless networks. In addition, the smart home service easily and conveniently controls lighting, energy, environment, and door cameras through a wall pad. However, while it has become a social issue due to the recent hacking accident of wall pads, personal information leakage and privacy infringement are expected. Accordingly, it is necessary to prepare preventive and countermeasures against security vulnerability factors of wall pads. Therefore, this study expects that it can be used as basic data for future smart home application and response technology development by examining the weak causes and countermeasures related to wall pads.

IT(Information Technology) 기술이 고도화됨에 따라 금융 분야에서는 스마트 컨트랙트에 기반하여 자산을 거래할 수 있는 DeFi(Decentralized Finance)가 발전하고 있다. 또한, 다양한 IoT(Internet of Things) 기기들로 구성된 융합환경이 상호 연결되며 IoBE(Internet of Blended Environment)가 조성되고 있다. IoBE의 구성요소 중 의료융합환경인 디지털 헬스케어는 스마트 의료 기기를 통해 진료서비스를 제공한다. 최근에는 디지털 헬스케어 내 자산 거래 수단으로 DeFi를 활용하기 위한 연구가 진행되고 있다. 그러나, 디지털 헬스케어 서비스에 DeFi가 활용될 수 있음에 따라 DeFi 내 보안 위협이 전파될 수 있다. 전파된 보안 위협은 DeFi에서의 디지털 화폐 탈취뿐만 아니라, 디지털 헬스케어 내민감 정보 탈취, 서비스 거부 공격 등 복합 위협으로 이어질 수 있다. 따라서, 본 논문에서는 DeFi의 취약점을 분석하고 이를 기반으로 디지털 헬스케어에서 발생 가능한 공격 시나리오를 도출한다.

Lately smartphone uasage is increasing and many Internet of Things (IoT) devices support wireless communications. Accordingly, small base stations which called femtocells are supplied to prevent saturation of existing base stations. However, unlike the original purpose of the femtocell with the advanced hacking technologies, Vulnerability such as gaining the administrator authority was discovered and this can cause serious problems such as the leakage of personal information of femtocell user. Therefore, identify security threats that may occur in the femtocell and it is necessary to ways for systematic vulnerability analysis. In this paper, We analyzed the security threats that can be generated in the femtocell and constructed a checklist for vulnerability analysis using the Threat Modeling method. Then, using the constructed checklist provides a scheme that can improve the safety of the femto cell through the actual analysis and taken the results of the femtocell vulnerabilities analysis.

Due to miniaturization of electronic devices and development of IoT(Internet of Things), embedded system have been used in various field. Meanwhile, there is a potential vulnerability by the insufficient of system's security. In this paper, we implement secure boot using TPM to protect the integrity of embedded system environment. The Suggestion considers the required availability in the embedded system and detects the system's tampering at secure boot process via TPM. In addition, we have reinforced the confidentiality through AES encryption of the kernel at secure boot.
