초록
스마트시티의 교통인프라 및 관제 체계가 디지털화되어감에 따라 통신상의 데이터 유출 및 원격해킹으로인한 자동차 제어, 교통시스템 마비 등의 다수의 보안위협이 발생될 수 있다. 특히 보안위협으로 인해 인명사고부터 크게는 교통인프라 마비 등과 같은 대형사고가 발생할 수 있다. 이는 사용자의 안전과 밀접한 관계이기 때문에 보안에 대한 이슈는 더욱 중요해졌다. 따라서, 차세대 교통시스템(C-ITS; Cooperative Intelligent Transport Systems)의 특성을 파악하는게 우선이다. C-ITS에서 발생할 수 있는 사이버 공격과 침해사고를분석하고, 이에 대한 해결책 및 보안 관련 기술들에 대한 연구가 필요하다. 본 논문에서는 C-ITS 환경에서발생할 수 있는 보안 이슈 및 요구사항 등에 대해 분석한다. 또한 각 주요국의 C-ITS 관련 보안 기술들과표준화 기술 내용을 분석하여 정리하고, 이를 기반으로 국내에서 안전한 C-ITS 환경을 위해 연구해야할 방향을 제언한다.
Abstract
As the smart city's traffic infrastructure and control system become digitized, several security threats, such as data leakage in communication and vehicle control due to remote hacking and traffic system paralysis may occur. In particular, due to security threats, major accidents such as human casualties and paralysis, of transportation infrastructure can occur. Since these are closely related to user safety, security issues have become more important. Therefore, it is a priority to understand the characteristics of the C-ITS(Cooperative Intelligent Transport Systems). It is necessary to analyze cyber attacks and intrusions that may occur in C-ITS, and to study solutions and security-related technologies. In this paper, we analyze security issues and requirements that may occur in the C-ITS environment. It analyzes and organizes each major country's C-ITS-related security technologies and standardization technologies. Based on this, we suggest the research direction for a safe C-ITS environment in Korea.
