  • IoT technology is currently being applied at various industrial sites and is developing as a core technology in the fourth industrial revolution. Along with IoT developments, awareness and importance of IoT security is increasing, and research on IoT security is underway to counter these threats. However, research trends in the context of IoT security awareness are insufficient. This paper is a research that analyzes the progress of R&D and IoT security in both domestic and international IoT and thus leads to improvements. The research covered the 229 papers and articles of domestic and foreign journals covering security fields as a main theme. Among them, detailed analyses of 96 papers related to IoT security were performed. Research has shown that many studies are being conducted on trends in IoT security, key management and privacy. A detailed study on the characteristics of services to apply IoT technologies and access control and authentication between IoT devices is needed, and a study that addressed the issues of privacy in IoT environments in Korea.

  • IoT (Internet of Things) is a collective term referring to application services that provide information through sensors/devices connected to the internet. The real world application of IoT is expanding fast along with growing number of sensors/devices. However, since IoT application relies on vertical combination of sensors/devices networks, information sharing within IoT services remains unresolved challenge. Consequently, IoT sensors/devices demand high construction and maintenance costs, rendering the creation of new IoT services potentially expensive. One solution is to launch an IoT open market for information sharing similar to that of App Store for smart-phones. Doing so will efficiently allow novel IoT services to emerge across various industries, because developers can purchase licenses to access IoT resources directly via an open market. Sharing IoT resource information through an open market will create an echo-system conducive for easy utilization of resources and communication between IoT service providers, resource owners, and developers. This paper proposes the new business model of IoT open market for information sharing, and the requirements for ensuring security and standardization of open markets.

  • 최근 IoT 기술이 홈케어, 헬스케어, 자동차, 교통, 농업, 제조업 등 다양한 분야에 적용되면서 신성장 동력의 핵심으로 IoT 서비스를 제공하거나 IoT 환경을 자체적으로 구축하여 산업현장에 도입하려는 기업이나 기관이 증가하고 있다. 그러나 IoT 환경은 인터넷을 통해 현실세계와 IoT 디바이스가 직접 연결되는 특성으로 인해서 IoT 보안의 중요성이 더욱 강조되고 있으며 IoT를 이용한 보안 사고 사례 및 취약점이 지속적으로 발표되면서 IoT 보안 위험 또한 계속 증가되고 있다. 이렇게 IoT 환경에는 많은 취약점과 보안 위협이 존재하기에 IoT 제품의 최초 설계/개발 단계부터 배포/설치/구성 단계, 운영/관리/폐기 단계까지 IoT 제품 및 서비스의 각 단계별로 보안 요구사항과 가이드라인을 적용하여 보안을 내재화하고 IoT 제품 및 서비스를 도입하는 사용자 입장에서 IoT 보안에 대해서 관심을 가지고 스스로 확인 할 수 있도록 보안 점검 기준이 필요하다. 본고에서는 IoT 디바이스의 특성과 보안 요구사항에 따른 보안 원칙 및 보안 가이드를 살펴보고 IoT 기술을 산업현장에 적용하고자 하는 기관/기업에 적용 가능한 IoT 디바이스의 보안 점검 기준을 제시한다.

  • 본 논문에서는 IoT 환경에서 IoT 게이트웨이를 통해 제공되고 있는 서비스 탐색 프로토콜에 대한 문제점을 분석하고 이를 해결하기 위한 해결방법에 대한 방향을 제시한다. 현재 다양한 IoT 서비스 탐색 프로토콜이 제안되어 있으며 제안된 서비스 탐색 프로토콜은 IP 기반 프로토콜과 non-IP 기반 프로토콜로 구분된다. 최근 IoT 기반 홈 네트워크 서비스 제공을 위해 스마트 IoT 게이트웨이가 개발되었다. 제안된 IoT 게이트웨이는 이종 네트워크 인터페이스에 대한 프로토콜 컨버팅 기능은 제공하고 있으나 서비스 탐색에 대한 홍보기능을 제공하고 있지 않다. 따라서 상이한 인터페이스로 구성된 IoT 디바이스에 대한 서비스 탐색 기능을 제공하지 못한다. 본 논문에서는 이런 문제점을 정의하고 이를 해결하기 위한 IoT 게이트웨이 내부 기능을 정의하고 추가적으로 공통 IoT 서비스 탐색 프로토콜 개발에 대한 방향을 제시한다.

  • IoT devices are used in many areas to perform various roles and functions in a cloud environment. However, a method of access control that can stably control the IoT device has not been proposed yet. In this paper, we propose a hierarchical multi-level property access control scheme that can perform stable access of IoT devices used in a cluster environment. In order to facilitate the access of the IoT device, the proposed method not only provides the ID key (security token) unique to the IoT device by providing the IoT Hub, but also allows the IoT Hub to authenticate the X.509 certificate and the private key, So that the private key of the IoT device can not be seen outside the IoT device. As a result of the performance evaluation, the proposed method improved the authentication accuracy by 10.5% on average and the processing time by 14.3%. The overhead of IoT Hub according to the number of IoT attributes was 9.1% lower than the conventional method.

  • Recently, IoT products with various functions are being developed. Through the combination of objects and information technology, convenient services that have not been imagined before are emerging. For a secure IoT environment, product security must be considered. However, the existing IoT products have various problems such as security vulnerability. In order to secure the security of IoT products, technical countermeasures as well as policy responses are needed. However, the legislation related to current IoT products has a limit to guarantee safety in IoT environment. In this paper, we analyze the limitations of the current legal system of IoT, and suggests ways to improve it.

  • IoT means things space networks that form the intelligent relationship such as sensing, networking, information processing about human being, things and service without explicit mutual cooperation of human being. Lately many IoT groups such as AllSeen Alliance, OIC launched a platform for IoT. Self-adaptive is aimed at implementation without the need for decisions of human being during the operation, so that the machine can respond to changes in its own determination. There is a need to apply the concept of self-adaptive to existing IoT and IoT platform. So In this paper, We look for trends of existing IoT, IoT platform and comparisons by applying a self-adaptive concept to IoT, IoT platform. In addition as an example of this paper, we suggest lacking self-adaptive elements to OIC.

  • With the rapid development of IoT(Internet of Things) technology, various convenient services such as smart home and smart city have been realized. However, IoT devices in unmanned environments are exposed to various security threats including eavesdropping and data forgery, information leakage due to unauthorized access. To build a secure IoT environment, it is necessary to use proper cryptographic technologies to IoT devices. But, it is impossible to apply the technologies applied in the existing IT environment, due to the limited resources of the IoT devices. In this paper, we survey the classification of IoT devices according to the performance and analyze the security requirements for IoT devices. Also we survey and analyze the use of cryptographic technologies in the current status of IoT open standard platform such as AllJoyn, oneM2M, IoTivity. Based on the research of cryptographic usage, we examine whether each platform satisfies security requirements. Each IoT open platform provides cryptographic technology for supporting security services such as confidentiality, integrity, authentication an authorization. However, resource constrained IoT devices such as blood pressure monitoring sensors are difficult to apply existing cryptographic techniques. Thus, it is necessary to study cryptographic technologies for power-limited and resource constrained IoT devices in unattended environments.

  • This paper presents an IoT platform of common interfaces that are flexible IoT applications and Connect the smart devices. The IoT platform includes automatic collaboration discovery the smart Device. It is different things case with connection each device through IoT Platforms are each device and application service. Due to these heterogeneities, it is quite advantages to develop applications working with derived IoT services. This circumstance needs the generic interface and results in a range of IoT architectures by not only the environments settings and discovery resource but also varied uniqe to implementation services working with IoT applications. Therefore, this suggestion of solve the problems and make it possible independent platforms always alive to connection with each devices based on the generic interface. The generic interface is heterogeneity-driven solve the problems and effectively contributions a platform that could be operated in diverse IoT Platforms.
