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.

The Internet of Things (IoT) provides data convergence and sharing functions, and IoT technology is the most fundamental core technology in creating new services by convergence of various cutting-edge technologies. However, there are different classification systems for the Internet of Things, and when it is limited to the domestic public sector, it is difficult to properly grasp the current status of which devices are installed and operated with what share, and systematic data or research The results are very difficult to find. Therefore, in this study, the relevance of the classification system for IoT devices was analyzed according to reality based on sales, shipments, and growth rate, and based on this, the actual share of IoT devices among domestic public institutions was analyzed in detail. The derived detailed analysis results are expected to be efficiently utilized in the process of selecting IoT devices for research and analysis to advance information protection technology such as responding to malicious code attacks on IoT devices, analyzing incidents, and strengthening security vulnerabilities.

최근 무선 통신 기술과 센서 디바이스들의 발달로 인터넷을 기반으로 모든 사물을 연결하여 사람과 사물, 사물과 사물 간의 정보를 상호 소통 가능한 센서 기반 IoT 환경이 다양한 분야에 활용되고 있다. 이러한 사물인터넷 환경은 지능형 서비스를 위해 다양하고 방대한 양의 디바이스 정보를 수집하며, 사용자 정보를 기반으로 서비스를 제공받고 디바이스를 제어해야 하며, 이기종 간의 디바이스를 활용함으로 올바른 표준을 기반으로 통신이 이루어져야 한다. 하지만, 사물인터넷 환경에서의 기존 연구나 표준 정의를 살펴보면, 현재 IoT 서비스에서는 이미 취약점이 들어난 커버로스 및 센서 노드의 수를 고려하지 않은 PKI 기반 보안 기술이 활용되고 있다. 따라서, 본 논문에서는 안전한 디바이스 인증을 위한 무인증서 기반 상호 인증 기법을 제안한다.

Internet of Things (IoT) is being globally spotlighted as a fundamental technology to realize hyper-connected society, and as new growth engines of nation and enterprises. Although the technical aspect of IoT receives a great deal of attention as a new business opportunity, the business aspect of IoT is suffering insufficient scholarly research and objective insight. Thus, the business aspect of IoT requires a thorough research on its service market and business opportunities. In order to stimulate the IoT service market and facilitate objective statistic data aggregation, this paper aims to suggest an IoT service categorization model. This model is comprised of three perspectives which are IoT purpose, IoT Player, and IoT Domain; they function as tools to comprehensively analyze the IoT industry. Efficacy of this model has been confirmed by simulating 117 IoT services on the model, in which the results successfully offered the market trend of the IoT service based on Case. This study is able to apply for basic research of IoT-Service Development Plan, and provide practical implications.

최근 사물 인터넷(Internet of Things)에 대한 관심은 가히 폭발적이라 할 수 있으며 주변의 모든 사물들이 연결되어 다양한 서비스를 제공하는 초연결 사회(Hyper Connected Society)에 대한 기대감이 어느 때보다 커지고 있다. 이러한 사물 인터넷을 활성화하기 위해서는 다양한 사물의 개발이 선행되어야 하는데 오픈소스 하드웨어를 이용하여 손쉽게 아이디어를 실현화할 수 있는 ICT DIY(Do It Yourself)는 중요한 역할을 할 것으로 판단된다. 그러나 ICT DIY로 개발된 디바이스가 인터넷이나 모바일 서비스와 연결되지 못하면 취미 이상으로 발전하기 어려우며, 이러한 상황을 극복하기 위해서는 다양한 IoT 플랫폼과의 연동이 필수적이다. 본 고에서는 현재까지 제안된 대표적인 IoT 플랫폼을 전용(proprietary) 플랫폼과 개방형(open) 플랫폼으로 구분하여 각각의 사례와 특장점을 분석하였다. 이를 통해 ICT DIY 개발이 단지 취미에 머물지 않고, 사물 인터넷의 중요한 접근 방안으로 인정받기 위해 IoT 플랫폼 기술을 어떻게 활용해야 하는지 살피고 향후 국내의 사물 인터넷 산업을 발전시켜 나갈 방안을 모색하고자 한다.

Korea has been showing a high interest in convergence centered on information and communication technologies for the past 10 years. However, with successful convergence of broadcasting and telecommunication sectors, successful convergence cases such as IPTV have been excluded. In some fields, The performance that citizens can experience is limited. In addition, the combination of the Internet of things and the big data shows that infinite data in the natural and social environment surrounding service users can be created and utilized to create better services. However, the division between departments and departments, And the limitations of policies and systems that can promote convergence of information and communication technologies. Therefore, in order to create new industries through the fusion of the Internet of things and big data, it is necessary to investigate what kind of inhibitory enzymes are present, to investigate the problems, to solve the problems, to develop technologies for activating the Internet and big data, And suggests ways to utilize the policy to promote convergence of related technologies.

Wireless Medium Access Control (MAC) and routing technologies are the basic building blocks making it possible the Internet of Things (IoT). These technologies have been the focus of substantial research in the last decade. Nevertheless, as new networking standards for IoT are being proposed and different solutions are patched together, evaluating the performance of the network becomes unclear. In this paper, a new overview of MAC and routing protocols for IoT and new interactions are given. The IEEE 802.15.4 MAC and Routing Protocol for Low-power Lossy Network (RPL) routing protocols are taken as reference to exemplify and illustrate the discussion. Experimental results show that contention-based access MACs may hurt the routing, unless these two are carefully designed together.
