This research investigates the objectives, concepts, and technical aspects of existing Smart Cities in theoretical terms in order to resolve any ambiguities the definition of Smart City currently has. Through this, theoretical recommendations for Smart City that targets elderly citizen are made. The elderly citizens in question are people currently in their mid-50s to early 60s, in order to adequately employ futuristic technologies into four major sectors: healthcare, post-retirement employment, community-based governance, and environment-friendly infrastructure. The research concludes that while the technical application of welfare to the elderlies through constructing a purposeful Smart City is desirable, environmental consideration should come in prior concern as a sustainable foundation of livelihood is needed for citizen accommodation.

Recently, Korea has been attracting the attention of smart city as a solution to urban problems along with the era of Forth Industrial Revolution. However, tourism, industry, and specific high-class residential complexes are being formed, and the disabled with information such as the elderly and disabled who can actually get help are not experienced. This study establishes the concept of smart city suitable for domestic and derives the priority of physical and non-physical elements of smart city considering information weakness. Smart City considering disabled with information has concluded that not only physical elements but also non-physical components are important, and derive the differences between the experts and the priorities of actual information weak people. We will propose a smart city development direction that takes into account information weak people that can be developed and advanced in response to the needs of information weak people.

Recently, research on solving problems that have introduced the concept of smart city in countries and companies around the world is in progress due to various urban problems. A smart city converges the city's ICT, connects all the city's components with a network, collects and delivers data, and consists of a supply chain composed of various IoT products and services. The increase in various cyber security threats and supply chain threats in smart cities is inevitable, in addition to establishing a framework such as supply chain security policy, authentication of each data provider and service according to data linkage and appropriate access control are required in a Zero-Trust point of view. To this end, a smart city security model has been developed for smart city security threats in Korea, but security requirements related to supply chain security and zero trust are insufficient. This paper examines overseas smart city security trends, presents international standard security requirements related to ISMS-P and supply chain security, as well as security requirements for applying zero trust related technologies to domestic smart city security models.

Smart cities are attracting attention as a new economic growth engine based on new technologies and means to solve side effects of urbanization such as a surge in energy consumption, deepening environmental pollution, and an increase in crime rates. In particular, as demand for non-face-to-face services increases due to COVID-19, the role of smart cities that can provide various online and offline non-face-to-face services is becoming more important. Therefore, this study defined smart city non-face-to-face services based on literature research on the concept and underlying technology of smart city, and analyzed consumer utility for each service using Conjoint analysis. In particular, differences in user preferences between Sejong City and Busan City, which are currently designated as national smart city pilot cities in Korea, were compared and analyzed, and based on the derived results, measures to improve the competitiveness of smart city services were suggested.

랜섬웨어는 더욱 지능화되고 표적화된 공격이 예상되고 클라우드와 사물인터넷 기기의 확산으로 공격의 범위 또한 지속적으로 확대될 것으로 보인다. 특히, 이러한 사물인터넷 기기들은 스마트 시티를 위한 기본 구성요소로 인식되므로 다양한 보안을 위한 연구가 진행되어야 한다. 본 논문에서는 데이터 중심의 스마트 시티를 위한 보안 요구사항 분석을 통해 다양한 스마트 시티 관련 공격을 살펴본다. 또한, 이러한 공격을 보안 서비스에 초점을 맞춰 분류한다. 이렇게 제시된 분류는 다양한 데이터 중심의 스마트 시티를 위한 보안 시스템 구축에 도움이 될 수 있을 것으로 기대한다.

This study proposes a smart city service revitalization policy based on communication facility infrastructure in 5G CPS - the core of the 4th industrial revolution, R&D, and related legislations. The 5G CPS is a converged form of ICT technologies, communications facilities, and physical systems. In this study, we propose methods of creating new services for the smart city domain based on communication facilities and the cloud platform in 5G CPS - first, by improving the communication methods classification system based on the facility scale; second, by establishing the national telecommunication facility infrastructure and making long-term investment; third, by reorganizing the Smart City Act aimed at activating new services; and lastly, by expanding the national data analytics R&D and policy support.

Smart cities are the product of modern urban planning that seeks to innovate information and communication technology and improve the quality of urban life. For the efficient operation of smart cities, data collected, stored, and processed in real time is a key resource. Therefore, data from smart cities collected in various fields must be managed safely, and personal information protection is paramount. In this study, a smart city data security model using blockchain technology was proposed to safely manage smart city data. The proposed model integrates IPFS into the blockchain network to distribute and store data to ensure data confidentiality and integrity, and encrypts data using CP-ABE to efficiently control access to data from users. In addition, privacy was guaranteed while enhancing the usability of data by using Homomorphic Encryption with data access control policies.
