The Internet of Things(IoT) is one of the key technologies in the Fourth Industrial Revolution. The IoT is a system that acquires information from various sensors and provides meaningful information to users. The method of obtaining information from sensor is using WIFI, Bluetooth and Server. is not accessible to external users because of different type of networks or local area communication. For this reason, there is a problem that external user cannot receive notification in regard to sensor information. In this paper, we want to establish a cloud message environment using Google's FCM(Firebase Cloud Messaging) and find out through experiments how users can receive notifications even if they are outside.

Internet of things (IoT) has been a focus of research and widespread. Security and privacy are the key issues for IoT applications, and still faced with some enormous challenges. In order to facilitate this emerging domain, we analyzed the research progress of IoT, and pay attention to the security. By means of deeply analyzing the security architecture and features, the security requirements are required. And, we surveyed the demands and requirements.

최근 다양한 산업 분야에서 사물인터넷(Internet of Things; IoT)에 관련된 연구가 활발히 진행되고 있다. 기존 네트워크 환경에서와 같이 IoT 또한 다양한 보안 공격으로부터 노출 되어 있으며, 여러 가지 보안 이슈가 존재한다. IoT 환경에서는 디바이스, 플랫폼, 통신프로토콜의 이종성 문제로 인하여 공통의 보안 서비스 제공이 힘들게 되고 이를 해결하기 위하여 상호운용성 제공이 가능한 표준이 필요하게 된다. 본고에서는 다양한 보안 이슈들로부터 안전한 IoT 환경 구축을 위하여, IoT 보안 관련 국내외 표준화 기관를 분석하고, 각 기관에서 제시하고 있는 IoT 보안 관련 표준 및 표준화 동향을 분석하고자 한다.

Many services have been developed that are based on smart devices, and security between devices is emphasized. A beacon on the current IoT(Internet of Things) services has been utilized in the commercial field and is being applied to the services of the home IoT. On the other hand, the beacon is weak to security using Bluetooth-based services. Therefore, it is important to strengthen the security of the beacon. This paper proposes a dual security technique that can enhance the security of beacon-based services. The dual security architecture and security process is proposed based on beacon and authentication service. In addition, mobile application was developed and validated based on the beacon for proving the suitability of the proposed technique. The experimental method for verification are the authentication failure case, such as 1st authentication fail, and authentication success case, such as 1st authentication success and 2nd authentication success. The components of the verification experiments consists of two beacons (matched with Beacon ID, mismatched with Beacon ID), one mobile device and authentication application. This was tested to verify the compatibility of the dual security architecture and 1st/2nd authentication process.

In recent years, the maker culture has realized the concept of 'making' itself through the latest technology of high technology. It is rapidly spreading as a maker's movement by sharing the production methods and information of individuals through the Internet. Countries that are leading the makers' movement expect the maker's movement to be the driving force for new value creation and economic growth from the point of view of things and the Internet. We are developing various types of open IoT platforms that can register various Internet devices and services manufactured and developed through DIY and realize interoperable services. Typical open IoT platforms require specialized API analysis capabilities and difficult access to general users due to difficult platform registration conditions and procedures. In this paper, we try to construct an open IoT platform that can be operated as a real service by creating a simple Internet application device and service application from a general manufacturer's point of view.

최근 다양한 주변의 정보들을 측정할 수 있는 센서, 수집된 정보에 기반하여 특정 디바이스나 시스템들을 움직이거나 제어할 수 있는 엑츄에이터 등 다양한 우리 주변의 기기들을 서로 연결하여 보다 스마트한 서비스들을 사용자들에게 제공해 주는 사물인터넷(Internet of Things, IoT)에 대한 기대와 관심이 증가하고 있으며, 관련 산업 및 시장의 규모가 급성장할 것으로 기대되어진다. 다양한 기기들이 인터넷에 연결되어 서로 연동되기 위해서는 국제 표준에 따른 개발이 필수적이며, 이를 위해 그동안 지역별로 별도로 진행되어오던 IoT 기술을 통합하여 하나의 글로벌 IoT 표준을 만들기 위해 oneM2M(원엠투엠) Partnership Project가 시작되었다. Release 1 oneM2M 표준이 개발되어 공표되고, 표준의 완성도가 높아짐에 따라, oneM2M 표준을 구현한 기기들의 호환성을 확인하고 표준 적합성을 확인하기 위한 테스팅 표준이 개발되어 지고 있다. 또한, 표준에 따라 개발된 사물인터넷 기기들을 인증하는 방법과 절차에 대한 논의가 시작되었다. 본 고에서는 다양한 ICT 관련 국제 시험 인증과 관련된 동향에 대해 살펴보고, oneM2M에서 개발 및 논의되고 있는 테스팅 관련 표준 및 시험인증 관련 내용을 소개한다.

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.
