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.

In industrial IoT environments, sensors generate data for their detection targets and deliver the data to IoT gateways. Therefore, managing large amounts of real-time sensor data is an essential feature for IoT gateways, and key-value storage engines are widely used to manage these sensor data. However, key-value storage engines used in IoT gateways do not take into account the characteristics of sensor data generated in industrial IoT environments, and this limits the performance of key-value storage engines. In this paper, we optimize the key-value storage engine by utilizing the features of sensor data in industrial IoT environments. The proposed optimization technique is to analyze the key, which is the input of a key-value storage engine, for further indexing. This reduces excessive write amplification and improves performance. We implement our optimization scheme in LevelDB and use the workload of the TPCx-IoT benchmark to evaluate our proposed scheme. From experimental results we show that our proposed technique achieves up to 21 times better than the existing scheme, and this shows that the proposed technique can perform high-speed data ingestion in industrial IoT environments.

산업사물인터넷(IIoT)은 사물인터넷(IoT)과 같이 기존의 여러 ICT 기술들과 무선센서네트워크 및 다양한 통신 기술들이 산업제어시스템에 적용된 것을 의미한다. IIoT는 일반적인 상용 IoT와 많은 부분 공통점과 그 기반 기술에 있어서의 동일한 성격을 가지지만 적용 대상 환경에 있어 차이를 가지고 있기 때문에 산업제어영역에서 IoT기술을 도입하기 위해서는 추가적으로 고려해야할 사항들이 존재한다. 본 논문에서는 IoT와 IIoT에 대하여 간단히 설명하고 IIoT 환경의 특수성에 대해서 다룬다. 그 후 상용 IoT에서 발생한 보안 사고관련 사례들을 살펴보고 산업제어영역에서 사이버보안 사고 발생시 그 피해 규모를 살펴본다. 그리고 IIoT를 도입하면서 보안관점에서 필요한 사항들에 대해 서술하였다.

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.

Recently IoT(Internet of Things) service industry has grown very rapidly. In this paper, we investigated the changes in IoT service industry as well as new direction of human life in future global society. Under these changing market conditions, competition has been also changed into global and ecological competition. But compared to the platform initiatives and ecological strategies of global companies, Korean companies' vision of building ecosystems is still unclear. In addition, there is a need of internetworking between mobile and IoT services. IoT security Protocol has weakness of leaking out information from Gateway which connected wire and wireless communication. As such, we investigate the structure of IoT and AI service ecosystem in order to gain strategic implications and insights for the security industry in this paper.

IoT(Internet of Things) has become a major issue as new type of convergence technology, expending existing of USNs(Ubiquitous Sensor Networks), NFC(Near Field Communication), and M2M(Machine to Machine). The IoT technology defines as a networking for things, which can establish intelligent links collaboratively for sensing networking and processing between each other without human intervention. The purpose of this study is to investigate to forecast the future distribution changes and orientation of contribution of distribution industry on IoT and to provide the implication of distribution changes. To become a global market leader, IoT requires much more development of core technology of IoT for distribution industry, new service creation and try to use a market-based demand side strategy to create markets. So, to become a global leader in distribution industry, this study results show that first of all establishment of standardization of IoT, privacy safeguards, security issues, stability and value were more important than others. The research findings suggest that the development goals of IoT should strive to boost the creation of a global leader in distribution industry and convenience to consider consumers' demands as the most important thing.

Recently, users' interest in IoT related products is increasing as the 4th industrial revolution has become social. The types and functions of sensors used in IoT devices are becoming increasingly diverse, and mutual authentication technology of IoT devices is required. In this paper, we propose an efficient double signature authentication scheme using Pascal's triangle theory so that different types of IoT devices can operate smoothly with each other. The proposed scheme divides the authentication path between IoT devices into two (main path and auxiliary path) to guarantee authentication and integrity of the IoT device. In addition, the proposed scheme is suitable for IoT devices that require a small capacity because they generate keys so that additional encryption algorithms are unnecessary when authenticating IoT devices. As a result of the performance evaluation, the delay time of the IoT device is improved by 6.9% and the overhead is 11.1% lower than that of the existing technique. The throughput of IoT devices was improved by an average of 12.5% over the existing techniques.
