Abstract

A concept of the "e-Navigation" was introduced in 2005 and implementation strategies are under way by IMO/IALA in the maritime safety area. Specially VTS is an important maritime traffic monitoring and aids to navigation system which is aims to improve safety, navigation efficiency and protect the marine environment. The demand of the inter-VTS networking has been increased and standardization is underway for realization of shore side collaboration for maritime safety in IALA. But there may be security problems in the inter-VTS networks if they have not proper security mechanism. The hacking of realtime ship position and sensitive maritime surveillance information caused a critical accident of vessel, human life and environment by terrorist. This paper aims to design of a secure inter-VTS network structure and related security protocol for secure sharing of sensitive maritime data.

해양 분야에서 "e-Navigation"의 개념이 2005년 처음 소개된 이후, 최근 2~3년 전부터 국제해사기구(IMO)와 항로표지협회(IALA)에서 이행전략과 기술 표준화가 급속히 추진되고 있다. 특히 해상교통관제시스템(VTS : Vessel Traffic Service)은 항행지원정보교류가 가능한 육상국으로서 선박 통항의 안전과 효율성을 증진시키고 환경을 보호하는 e-Navigation의 핵심적 시스템으로 인식되고 있다. 최근 IALA VTS Committee에서는 출항에서 도착항까지 항행지원을 위하여 VTS 시스템간 정보 교류(IVEF:Inter-VTS Data Exchange Format)에 대한 요청으로 표준화가 진행되고 있다. 그러나 이러한 해상의 실시간 선박 교통흐름 정보는 국가적으로도 보안에 민감한 정보로서, 테러 등 역기능에 대한 우려가 있어, 안전한 정보교환은 필수적인 요소이다. 따라서 본 논문에서는 상호연동을 위한 보안 프로토콜을 설계하고 안전한 데이터 전송을 위한 보안 구조를 제시하고자 한다.
