인류를 구할 8가지 기술 중 한가지로 스마트 그리드(Smart Grid)가 소개된 바 있다. 즉 에너지 사용의 효율성을 높여 전력량과 비용을 줄이고 전력 공급자와 소비자 간의 실시간 정보교환이 가능한 지능형 전력망이라 할 수 있다. 그러나 스마트 그리드의 취약점들로 인하여, Smart Meter가 해킹을 당해 정전으로 인한 대규모 피해가 예상 될 수 있다. 본 논문에서는 Smart Meter에 대한 취약점 분석을 실시하고, Smart Meter의 Gateway 보안을 위해서 접근제어와 인증을 통해, 사용자의 접근과 개폐에 대한 보안을 실시한다. 범죄가 발생했을 포렌식 자료를 통한 법적 책임에 관한 내용을 연구한다.

A stable protein source is required to support the rapidly increasing global population, and fishery products are a particularly important part of the required protein supply. However, due to continued overfishing, fishery resources are depleted, and the number of fish caught by fishing boats has stagnated. Consequently, the aquaculture industry is becoming increasingly important. Internationally, smart aquaculture technology that minimizes labor and environmental pollution has been established through technological developments supported by large investments in automation and water treatment technology over the last several decades. In the case of Korea, the aquaculture industry has not yet emerged as a labor-intensive primary industry. However, in recent years various attempts have been made to apply ICT technology to aquaculture to overcome these problems. In this study, domestic and foreign technologies and patent trends for smart aquaculture are analyzed. In addition, the current status of the smart aquaculture cluster business that the Ministry of Oceans and Fisheries has been promoting since 2019 to utilize ICT technology in aquaculture is introduced.

스마트그리드는 기존의 전력망에 IT기술을 접목하여 기존 전력망의 노후화, 안정적인 전력 공급 등의 문제를 해결할 수 있도록 개발되었고 안정적인 전력 공급, 신재생에너지의 효율적 활용, 각 가정의 전력 구매/판매 가능 등의 장점을 갖고 있다. 하지만 폐쇄 망으로 운영되는 환경을 공개망으로 전환하기 때문에 소비자의 정보, 전력 사용량 등을 전송하는 통신과정에서 악성코드 유포, 해킹 등의 보안 위협에 노출될 수 있다. 따라서 본 논문에서는 스마트미터와 AMI 서버간의 안전한 통신을 할 수 있는 안전한 키 분배 기법을 제안한다.

최근 그린 IT 에 대한 관심이 점차 고조되면서, 이 사업의 일환으로 저탄소, 녹색 성장을 위한 지능형 전력망인 스마트 그리드의 도입이 발 빠르게 진행되고 있다. 스마트 그리드를 통해 전력 공급자와 소비자의 양방향 통신으로 에너지 효율의 최적화가 가능하지만, 동시에 사이버 공격에 의한 개인정보의 노출위험에 대한 우려도 제기되고 있는 상황이다. 데이터의 안전한 전송을 위해 다양한 암호화 방식이 제안되고 있으며, 본 논문에서는 기밀성에만 초점을 맞춘 Homomorphic 암호화의 허점을 보완하기 위하여 additive Homomorphic 방식을 기반으로 하여 데이터 무결성을 보장 할 수 있는 새로운 방식을 제안하였다. 이 메커니즘을 통해 데이터는 최종 목적지까지 안전하게 도달했으며, 위조 및 변조 되지 않았다는 것을 보장받을 수 있다.

This study aims at providing basic data for product planning to design smart clothing and to develop applications, focusing on consumers by satisfying their emotions through analyzing emotional factors on smart clothing, comparing emotional differences between conventional clothing and it, reviewing changes of consumers' emotion by integrating the product and clothing and researching differences of preference and purchase intention between smart clothing and traditional one. As the results of the study, emotional factors for smart clothing were analyzed with total 6 including 'technical', 'comfort', 'aesthetic', 'modern', 'fun' and 'multiple' factors. Among them, except for 'comport', five emotional factors showed emotional factors between conventional sport-casual clothing and smart clothing. That is, emotional factors of 'technical', 'aesthetic', 'modern', 'fun' and 'multiple' were emphasized more in smart clothing than conventional ones, indicating that they should be considered in planning products of smart clothing. Though there was no significant difference of preference between smart clothing and conventional clothing, in case of comparison of averages, that of smart clothing was a little higher. For purchase intention, smart clothing was lower than the conventional clothing. So preference seems to be not directly related to consumers' immediate purchase. To make consumers' interests and preference to result in purchase, it is necessary to develop smart clothing with more various applications and to prepare commercializing strategies. As the results of the analysis on free-descriptive questionnaire survey, consumers were interested in development of smart clothing to help diet with functions including energy harvesting from body motion, calorification and perspiration, measurement of motion and calory consumption as well as health-care type smart clothing to measure heartbeat and ECG. Reflecting these requirements from the consumers, they should be utilized as guidance to develop smart clothing in the future.

Due to changes in the energy environment, it's very popular to introduce the solar energy at home. More effective energy management is achieved together with an energy storage system(ESS). The electricity generated by solar can be used effectively to achieve the peak cut and price reduction. In this paper, we developed Smart Energy Profile(SEP) to make an ESS as a component of home energy management system(HEMS) cooperating with home network. First, we defined the functions equipped on the ESS and then developed a standard-based protocol to achieve compatibility between products. Our main contribution is to establish the foundation to introduce the HEMS at home.
