현대의 모든 기기나 사물들은 인터넷과 연결이 되어 있어서 직접 조작을 하지 않아도 원격으로 쉽게 사물들을 조작할 수 있고, 사물들이 스스로 필요한 것들을 확인하여 사용자에게 알려주는 시대가 되었다. 사용자 생활면에서는 편리한 시대가 되었다고 볼 수 있다 하지만 보안면 에서는 나쁜 의도를 가진 사용자들에게는 좋은 먹잇감이 되었다. 이 논문에서는 해킹을 시도하거나 다른 사람에게 손해를 끼치려는 사람들을 방지하기 위해 블록체인의 보안 기술을 이용하여 IOT의 보안 기능을 향상하는 논문을 작성하려고 한다.

As the IOT technology has developed, it becomes more big issues about IOT device security. An account management is a nerve-in-the-box routine job for the system administrator and users who manage the several hundreds IOT devices(IP camera, Home IOT, the various measuring equipment). This study is to propose the account management system by the hierarchical design and it is efficient for the user to manipulate the account management. The designed system supports 6 functions for the account management and apply the advanced technologies for the existed system. After the performance of the designed system is validated successfully by the authoritative test, the designed system is applied for the relative fields. And it is on going for the development of the smart account management system by applying the AI technique.

IOT middleware is required to play a pivotal role in interpreting, managing, and controlling data information of Internet devices (sensors, etc.). In particular, the root industry has different process flows for different industries, and there are various data processing requirements for each company. Therefore, a general purpose IOT middleware is needed to accommodate this. The IOT middleware structure proposed by this paper is a plug-in that can be used as an engine part for middleware basic processes such as communication, data collection, processing and service linkage, We propose a flexible and effective smart process for root industry. In addition, we propose a method to strengthen prevention and security against tampering, deodorization, etc. through encryption of network data between middleware plug - in and related service layer. We propose a system that will be developed as an IOT middleware platform that is specialized in the root industry so that it can be extended in various network protocols such as MQTT, COAP, XAMP.

The Internet of things is the infrastructure that can communicate with each other by exchanging information by installing antennas that can communicate with all things in the world. The reason why the Internet of Things is the core of the Fourth Industrial Revolution is that data is collected through the Internet to be. Technology of things Internet and Trend of Things Internet IoT (Internet of Things) is a concept that enables internet connection and communication between devices equipped with various sensors. It is the core IT trend of lot, technology such as big data, mobile, cloud And to provide information for the development of the industrial environment through research on the importance of the Internet of things, the core of the Fourth Industrial Revolution and the processing and analysis techniques of Big Data. By providing various security measures and future technologies, This study was conducted to contribute to management.

Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata or control individual target through wireless waves. Connecting RFID reader to the terminal of Internet, the readers can identify, track and monitor the objects attached with tags globally, automatically, and in real time, if needed. This is the so-called Internet of Things (IOT). RFID is often seen as a prerequisite for the IOT. This paper surveys the technologies of RFID and IOT, discusses the applications and challenges of RFID technology used in IoT.

While the legislation on the protection of personal information in public institutions was enacted and amended, the guidelines and laws on information security were focused, contracted and realized with focus on specific institutions. Mutual laws and guidelines have been applied and realized for the dual purpose of securing both the asset of macroscopic information and the asset of personally identification information, which are mutually different media information. However, in a bid to present the definition and direction of the fourth industrial revolution in 2017, a variety of products and solutions for security designed to ensure the best safety line of the 21st century, and the third technology with the comprehensive coverage for all these fields, a number of solutions and technologies, including IOT(: Internet of Things), ICT Internet of Things(: ICT), ICT Cloud, and AI (: Artificial Intelligence) are pouring into the security market as if plastic doll toys were manufactured in massive scale into the market. With the rising need for guaranteeing the interrelation for securities with dualistic physical, administrative, logical and psychological differences, that is, information security and personal information security that are classified into two main categories and for the enhanced security for integrated management and technical application, the study aims to acquire the optimal security by analyzing the interrelationship between the two cases and applying it to the study results.

우편함이 멀리 떨어져 있으면 우편이 도착해도 실시간으로 확인이 불가능하다. 또한 잠금 여부에 따라 누구나 쉽게 우편을 수령할 수 있으므로 도난의 위험이 있다. 따라서 사물 인터넷을 사용하여 스마트폰으로 실시간 알림이 뜨는 자동화 시스템을 도입해 편의성과 보안 가능성을 높인 우편함 시스템이 필요하다. 본 논문에서는 사물인터넷 기술을 이용한 우편함 개발 경험을 바탕으로 자동화 시스템의 부재로 인해 발생하는 문제점을 알아보고 이를 해결하기 위한 방법을 제시한다.

본 논문은 4차산업이 발달함에 따라 일반인들도 쉽게 인공지능과 결합한 CCTV를 구축할 수 있는 것을 목표로 하며, 더 나아가 1급보안시설인 항만에서 자주 발생하는 입국자 월담, 행방불명들을 인공지능 CCTV로 감시하여 보다 쉽게 잡고 인력감소로 경제적 이익을 도모할 수 있다.
