Owing to various restrictions in-field application, the low-speed, low-power-based industrial Internet-of-Things (IoT) network built in extremely harsh industrial environment sites requires multi-hop, channel hopping, and low-latency transmission characteristics. In the past, wired networks were used in industrial facilities; however, network technologies based on the Industrial IoT Network standard standardized for industrial applications, such as WirelessIO link, WirelessHART, SmartMesh, and eStar Link satisfy industrial requirements. Recently, the use of industrial IoT networks in industrial facilities has rapidly expanded. This paper covers the developments in industrial IoT network technologies and summarizes the major industrial IoT standard technologies that meets the requirements of industrial sites.

사물인터넷(IoT, Internet of Things)의 발전과 스마트 기기의 보급으로 개인정보 등과 같은 중요한 정보를 빠르고 안전하게 암호화 및 전송할 필요가 생겼다. 사물인터넷과 같이 제한된 환경에서 암호화를 할 수 있도록 설계된 암호기술을 경량 암호기술이라 한다. 본 논문에서는 국제표준화기구/국제전기표준화위원회 합동기술위원회 1 연구그룹 27 작업그룹 2(ISO/IEC JTC 1/SC 27 WG2)에서 진행되고 있는 경량 암호기술의 표준화 동향을 중심으로 우리나라의 경량 암호기술과 함께 고찰하고자 한다.

In recent years, the importance of IoT (Internet of Things) is emphasized by information communication technologies and the performance of various smart devices are rapidly developed and applied in the real world. In this paper, we propose a process-driven IoT-object collaboration model to specify and execute a IoT service based on processes. That is, the purpose of this paper is to suggest a formal method in order to describe a IoT service into a group of tasks having execution order and collaboration between IoT-objects in charge of the enactment of a task. Conclusively, through the proposed model, we expect that IoT services will be automatically executed, analyzed, monitored and reused in the process-driven IoT computing environment.

정보통신 기술의 발전으로 우리가 사용하는 모든 사물들이 네트워크를 통해서 사람과 상호 연결을 할 수 있는 시대로 접근하는 추세이다. 또한 ICT분야의 융합이 빠르게 발전하고 있으며, 이를 통해서 유비쿼터스 환경으로 도약하고 있다. 스마트 폰 이후에 센서 대중화, 비용 절약, 기기 보급 확산, 네트워크의 확대 등의 이유로 사물 통신 M2M(Machine to Machine)/사물 인터넷 IoT(Internet of Things) 기술이 점차 활용되고 있으며, 관련 분야의 많은 연구가 진행 중에 있다. 본 논문에서는 이러한 IoT/M2M의 기술 및 표준화 동향을 살펴보고 발전 방향을 예상해 보고자 한다.

사물인터넷(Internet of Things: IoT)이란 모든 사물이 인터넷에 연결되어 상호 간에 직접 통신하는, 향후 정보통신의 미래 인프라 및 서비스이다. 이것이 필요한 이유는 초연결 사회에 기반을 둔 삶의 질 향상과 생산성 향상에 있으며, 최종적으로는 국가 자체의 인프라, 더 나아가서는 인류를 위한 중추 신경계를 이루기 때문에 무엇보다 중요하다. IoT는 셀룰러 이동통신 기반의 IoT와 비셀룰러기반의 IoT로 대분되어 오다가 두 분야의 융합이 이루어지고 있다. 그러나 IoT는 현재 거품 최고조기에 있으며, 아직까지 주목할 만한 큰 수익모델이 없는 상태이다. 그 이유는 사물인터넷 서비스 활성화에 가장 걸림돌이 되어온 보안문제, 배터리수명, 통신거리, IoT 디바이스를 포함한 솔루션 가격 그리고 월정료 문제가 여전히 존재하기 때문이다. 최근 이들 문제 해결을 목적으로, 대량의 IoT 디바이스를 필요로 하는 새로운 사물인터넷 커넥티비티에 대한 재정의, 표준화 및 솔루션 개발이 핫이슈이다. 본고에서는 셀룰라 및 비셀룰라 IoT기반의 Low Power Wide Area(LPWA), 즉 저전력 광역 IoT에 대한 시장, 기술 및 솔루션 비교 그리고 표준화 동향을 다룬다. 또한, 비셀룰라기반 즉 비면허대역과 프리밴드 활용을 통한 기술적 및 정책적 대응전략을 살펴본다.

Recently, IoT has been supported by ICT technology with a variety of ICT powers. In May 2014, Information and Communication Strategy Committee announced the 'Basic plan for Internet of Things'. Also on Febuary 24 this SAME year, KISA(Korea Internet&Security Agency) provides many projects related to IoT, such as announcement of 'K-Global Project' for start-up and venture support related to IoT and ICT companies. In contrast to the various services of Internet of Things, when a connection is made between object-to-object or person-to-object wired and wireless networks, security threats have occurred in the process of communication. We analyzed these kinds of security threats related to Internet of things, and gave a consideration for requirement.

Based on the Internet of Things technology, one of the core technologies of the fourth industrial revolution, our Ministry of Defense is also pushing to establish M-IoT in defense area to improve management efficiency, innovate military culture and strengthen military power. However, devices connected to the Military Internet of Things can be easily exposed to various of cyber threats as most of them are developed and with a focus on improving sensing and communication skills that collect and transmit data. And it is not easy to uniquely identify the numerous heterogeneous devices, and to establish a secure communication channel between devices or between devices and management servers. In this paper, based on PUF technology, we propose a novel key management scheme that can uniquely identify the various devices, and generate the secret keys needed for the establishment of a secure communication channel using non-replicable information generated by the PUF. We also analyze the efficiency of our proposed scheme through comparison with existing key management scheme and verify the logic and security using BAN Logic.

Internet of Things(IoT) using a variety of technologies in combination provides a convenient, elevated range of services to users. IoT has been noted in combining the fields of medical service in particular. However, with the advent and growing of IoT, the more medical services are evolving, security problems caused by leakage of personal health information will become more serious. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. Therefore, the introduction of the IoT in the healthcare industry requires the medical information security as a prerequisite. This study analyzes security status and trend of IoT, personal medical information leakage cases, the health information protection measures in accordance with the life cycle of medical information, and the standardized protection technologies.

This paper tries to find the implications applied to art institutions of Korea by analyzing what the content and consequences of services of the Cleveland Museum of Art provided after the Internet of Things adoption in the theoretical perspectives strengthening service marketing through the Internet of Things increases visits and participation in the museum. For analysis, journal articles, statistics, and government press releases, news articles, web pages, web page articles are collected. The results are first, the application of digital and social media is positive in visit to the museum and monetization. Second, the introduction of the Internet of Things will enhance the museum's 'Education', 'Accessibility', 'Communications' services, as well as significantly increase on and offline participation by activating experience. Third, technical support from related companies with the support of local government funds is essential to build the system. Consequently, in order to enable the participation of the spectators in the galleries it is proposed aggressive adoption of such digital technology in domestic barren market of Internet of Things.
